Eudromaeosaurs in GURPS

A group of bipedal carnivores, famed for the scythe-like talons on the second toe of each foot. Their short S-shaped necks were flexible to allow precision bites, while their long, stiff tails provided balance. Evidence suggests that they were fully feathered, including long feathers on the arms. While not capable of true flight, they may have used their wing-like arms for stabilisation while subduing prey or to control jumps. Although they had hands, their fingers were not well suited to manipulating objects.

Dromaeosaurinae

This group had broad, powerful jaws and reached the largest body sizes among the family. There is some evidence that they hunted in packs.

Deinonychus and Utahraptor lived in Laramidia, now western North America, during the early Cretaceous. Dakotaraptor and Dromaeosaurus occupied the same landmass in the late Cretaceous, while Achillobator was found in East Asia.

Hadrosaurine Dinosaurs in GURPS

The ‘duck-billed’ dinosaurs had wide, flat beaks, and numerous small teeth. Their bodies were narrow and deep, and their tails straight and tapered, giving them a ‘teardrop’ outline. They usually walked on four legs, but could rise to a bipedal stance.

They seem to have lived in herds and engaged in extensive parental care. All date to the late Cretaceous.

Brachylophosaurini

This tribe inhabited the forests of Laramidia, now the west of North America. They ate a wide variety of vegetation including tough material like rotting wood. They were highly social, with herds of thousands of individuals of all ages.

The history of the genus shows a trend towards increasing size and development of a small horizontal crest across the upper skull. Acristavus had no crest, Probrachylophosaurus had a very modest one, and Brachylophosaurus had the most developed form, extending past the back of the skull. Maiasaura appears to have been an off-shoot and had small spikes above each eye. These crests may have been for display or used in pushing contests.

Saurolophini

Saurolophus had a long bony spike projecting backwards from the top of its head and a spoon-shaped bill. S. osborni lived on the east coast of Laramidia, while S. angustirostris was found in East Asia. Augustynolophus looked very similar and lived on the west coast of Laramidia. Prosaurolophus also lived in Laramidia and had a small, flat crest instead of a spike.

Augustynolophus uses the same profile as S. osborni.

Iguanadontid Dinosaurs in GURPS

These bulky herbivores had blunt beaks as well as chewing teeth in tall and narrow skulls. Their thick necks led to deep bodies and sharply tapering tails. They could walk on two legs or four. The ‘hands’ had hoof-like claws on most of the digits, but the thumb was a sharp spike and the last digit was flexible and possibly able to grasp objects. The rear feet had three blunt claws. They were low-level browsers and seem to have gathered in mixed-age herds.

All known iguanadontids lived in the early Cretaceous. Iguanadon itself lived in Europe, as did Barilium, Brightstoneus, Darwinsaurus, Dollodon, Hypselospinus, and Proa. Dakotadon and Iguanacollosus inhabited North America, while Lurdusaurus and Ouranosaurus lived in Africa. East Asia had Altirhinus, Equijubus, Fukuisaurus, Jinzhousaurus, Lanzhousaurus, Probactrosaurus, and Xuwulong.

Diplodocoid Dinosaurs in GURPS

Diplodocoids followed the general body-plan of sauropod dinosaurs: a big oval torso, supported on four pillar-like legs, a long neck with a small head, and a long tail. Their snouts were long, had nostrils on top, and peg-like teeth for stripping vegetation. The rear legs were a bit longer than the front ones, and strong enough to support a rearing posture while standing. Each of the front feet had a single sharp claw projecting inwards.

There is evidence that many species of diplodocoid gathered in herds, usually with animals of similar age.

Whip Tails

The long, whip-like tips of diplodocoid tails have prompted speculation that they might have been used to strike other dinosaurs, or produce a loud noise by moving fast enough to break the sound barrier.

Used as a weapon, the tail can strike into side and rear hexes, with a reach determined by the creature’s SM (Size Modifier and Reach, GURPS Basic Set, p. 402). It does the same damage as trampling.

When used as a noise-maker, the tail produces about 200 dB, which is enough to rupture eardrums at close range. At 1 yard, roll HT−5 to avoid Deafness for 1d Months. If successful, roll HT−7 to avoid Hard of Hearing for 1 day. Each doubling of distance gives +1 to resist. The sound can be heard on an unmodified hearing roll up to 32 miles away. See GURPS Powers: Enhanced Senses, p. 21 for further details.

Apatosaurs

Apatosaurus and Brontosaurus had especially short torsos and extra-long tails. A fleshy ridge ran down their spines, tallest above their hips and may have been topped with short spikes. Their necks were thick, studded with keratinous knobs, and well suited to smashing into each other.

They lived in western Laurasia (now the Western United States) during the late Jurassic. They are believed to have been grazers, eating mostly ferns and other low vegetation.

Dicraeosaurids

Dicraeosaurus hansemanni and D. sattleri lived in eastern Gondwana, now East Africa, during the late Jurassic. They had relatively short necks and some kind of hump or short sail above their hips. Amargasaurus lived in south-western Gondwana, now South America, during the early Cretaceous. It had similar anatomy, with the addition of dramatic spikes on the back of its neck.

Treat the neck spikes as Long Spines which do 1d impaling damage, only for the neck location (free attack at skill 6 for anyone in close combat with the neck hexes, automatic hit against those who grapple the neck, see GURPS Basic Set, p. 88).

Diplodocines

Diplodocus and its relatives were all very long and slender. Supersaurus was the largest and also most heavily built. Like the apatosaurs they lived in western Laurasia during the late Jurassic.

Rebbachisaurines

This was the last surviving branch of the diplodocoids. Their ‘primitive’ anatomy indicates they branched off from the others early on, but they are only known from the early Cretaceous. Rebbachisaurus garasbae, Nigersaurus, and Tatouinea were from northern Gondwana, now North Africa. R. agrioensis and Zapalasaurus were from south-western Gondwana, now South America. Demandasaurus was from an island between Gondwana and Laurasia, now Spain.

Extinct rhinos in GURPS

The extinct relatives of rhinoceroses were similar to those we know today; heavyweight, thick-skinned herbivores. Many of them had ‘horns’ made of compressed hair, or tusk-like incisors on their lower jaw. Most were probably solitary animals which relied on a combination of size and aggression to fend off predators.

Aceratherium

A hornless rhino, with chisel-like lower incisors, which lived throughout Eurasia from the early to late Miocene.

Aceratherium by Heinrich Harder (1920).

Its relatives include Plesiaceratherium which lived also lived in Eurasia at the same time, and Aphelops from North America during the middle Miocene to early Pliocene. Chilotherium lived in Africa and Eurasia from the middle Miocene to late Pliocene and had long, sharp tusks.

For the smaller species of Chilotherium (2,000 lbs.), exchange ‘bite’ with ‘gore’ (damage 2d+4 cutting). Larger ones (5,000 lbs.) increase ST and HP to 34 (damage 3d+5 with gore or trample) and SM to +3 (4 hexes).

Coleodonta

The ‘woolly rhino’, Coleodonta antiquitatis, lived in the ‘mammoth steppe’ of Eurasia from the middle Pliocene to the late Pleistocene. Its legs were short, and its body long, with a large fatty hump above the shoulder. It was insulated not just with a thick pelt of hair, but also a substantial layer of fat, making it very bulky. Frozen remains show their fur was pale brown in youth but darkened with age, and cave paintings seem to show a darker band around the belly. Like many cold-adapted animals, it had small ears and a short tail. The head sported two horns, one behind the other, the front one being larger and flattened into a blade-like shape.

Stephanorhinus was a close relative of the woolly rhino which was better adapted to temperate conditions. The ‘Etruscan rhino’, S. etruscus, inhabited Europe from the early to middle Pleistocene. The ‘forest rhino’, S. kirchbergensis, lived throughout Eurasia from the early to late Pleistocene, while the smaller ‘steppe rhino’, S. hemitoechus, lived in Europe and the Middle east from the middle to late Pleistocene.

Teleoceras

A short-legged hippo-like rhino from North America. They lived from the early Miocene to the middle Pliocene. Like hippos, they grazed on grasses but may have spent a lot of time in water. They were highly sexually dimorphic and lived in herds, apparently led by a dominant male. Younger males may have lived alone or in separate bachelor herds. Some species had very small horns, while others had none at all.

Extinct elephantimorphs in GURPS

The ancestors and relatives of modern elephants all had a similar body plan: a rotund torso, four pillar-like legs, a relatively small tail, and a large head with a flexible trunk. Most of them were more heavily built than elephants. They varied in size and preferred habitat, but the most obvious difference between them were in their teeth. Although palaeontologists tend to concentrate on the molars, what stands out to the layman is the often bizarre forms of their tusks (enlarged incisors which project forward from the mouth).

Mastodon by Charles R. Knight (1897).

Although it is difficult to be sure about the behaviour of long-extinct animals, most experts believe that they had similar lifestyles to elephants. That means they were intelligent, social animals which gathered in family groups or herds, wandered long distances without claiming territory, and ate a wide variety of plants. Modern elephants herds are generally single-sex, although female herds include young males and may have an 'attached' adult male who travels with them for a time, and bulls are sometimes solitary. Older elephants take leadership roles, with female herds usually led by a matriarch, while male ones have a somewhat looser structure. These details are likely to have been different in at least some extinct species, but it is impossible to tell for sure.

Sexual Dimorphism

Male elephants grow significantly larger than females, and have proportionately bigger tusks. It is assumed that their extinct relatives had similar differences, although it is often hard to confirm this from their remains. The full profiles below represent males, with rules for females presented in the options below.

Mature bull elephants periodically experience a state known as musth, where their levels of testosterone rise dramatically. In GURPS terms, this would result in them occasionally suffering from Bad Temper and Lecherousness. It isn't clear exactly when musth evolved, but hormones preserved in mammoth tusks indicate they had it, and it may have affected the entire proboscidean order.

Gomphotheres

One of the earliest members of its group, Gomphotherium had four tusks, with the lower ones growing close together and the upper ones curving away from each other. It evolved in Africa around the start of the Miocene. From there it spread through Eurasia, reaching North America by the middle Miocene. It went extinct in Europe by the late Miocene, but survived in North America until the start of the Pliocene. The genus includes numerous species, most of them fairly similar, although the Eurasian species G. steinheimense was notably larger than others.

Gomphotherium by Charles R. Knight (1901).

Some later gomphotheres lost their lower tusks while the upper ones got larger. Stegomastodon had strongly curved tusks and lived in North America from the middle Pliocene to the early Pleistocene. Cuvieronius had long tusks and lived in the Americas during the Pleistocene. Notiomastodon had short tusks and lived in South America from the middle Pleistocene to the early Holocene. Anancus had very long, straight tusks and lived in Africa and Eurasia from the late Miocene to the early Pleistocene.

Others evolved flat, shovel-shaped lower tusks, which appear to have been used for digging, scraping, and scooping up water plants. Tetralophodon lived in Africa and Eurasia during the Miocene and may have been the ancestor of Anancus. It had long upper tusks and short lower ones. The Ambelodontid family all had short upper tusks and large, flat lower ones. Amebelodon fricki lived in the Great Plains of North America during the late Miocene. It was preceded by the smaller A. floridanus, which lived along the Gulf Coast. The closely related Konobelodon also lived during the late Miocene, with a range stretching from North America, across Eurasia, and into North Africa. Another shovel-tusker, Platybelodon, lived in Eurasia during the middle Miocene and had a spoon-shaped lower jaw.

Mammoths

The woolly mammoth, Mammuthus primigenius, is among the most famous of ice-age animals. It resembled its living relative, the Asian elephant, in general outline, although it was larger and had proportionately smaller ears, shorter legs and tail, and much larger and more curved tusks. The bulge on top of its head was more pronounced, as was the hump above its shoulders which made the back slope down towards the hindquarters. Of course, the most obvious difference was the one which led to its popular name; the heavy coat of fur.

Mammoths by Charles R. Knight (1916).

M. primigenius roamed the mammoth steppe which stretched across Europe and Northern Asia during the middle Pleistocene. During the late Pleistocene they crossed the Bering land bridge into North America. Their population began to decline at the end of the Pleistocene, disappearing from Europe by the early Holocene and dwindling to a few isolated populations in Alaska and Siberia which eventually disappeared in the middle Holocene. These last mammoths were stunted and inbred due to being trapped on islands too small to maintain a healthy population.

The first mammoth was M. subplanifrons which emerged in South-East Africa in the late Miocene. These were probably no more hairy than elephants. By the late Pliocene, the only African mammoths were M. africanavus from the North of the continent, which died out in the early Pleistocene. However, mammoths had crossed the Sinai peninsula and the species M. rumanus spread through Europe and Asia during the late Pliocene. They evolved into the Southern mammoth, M. meridionalis. An isolated population of Southern mammoths on the island of Crete evolved into a dwarf species, M. creticus during the early to middle Pleistocene.

The ‘steppe mammoth’ M. trogontherii appeared in East Asia during the early Pleistocene and gradually spread across Eurasia and into North America, replacing the Southern mammoth by the middle Pleistocene. The steppe mammoth was the first mammoth adapted to cold climates and probably the first to be covered in thick fur. It evolved into the woolly mammoth, the late Pleistocene Sardinian dwarf mammoth, M. lamarmorai, and the Columbian mammoth, M. columbi, which inhabited North America from the middle Pleistocene until the end of the Pleistocene. They occupied warmer regions and were probably less hairy than woolly mammoths. An isolated population of Columbian mammoths on the California channel islands evolved into pygmy mammoths, M. exillis, which also went extinct at the end of the Pleistocene.

Mammutids

Mastodons had extremely stout builds, huge tusks on the upper jaw, and flat skulls. Their pelvis was very broad and their leg bones very thick. Although often pictured as hairy, there is little evidence to support this, and they may have had elephant-like skin with sparse hairs. The type species, Mammut americanum, was found throughout North America from the middle Pliocene to the late Pleistocene. During warm interglacial periods it lived as far north as Alaska and Greenland, but otherwise kept to the warmer south. Its ancestor M. raki was somewhat smaller and inhabited a similar area from the late Miocene to the early Pliocene. Several other species of mastodon lived in various regions of the continent until the late Pleistocene, most of them around the same size as M. raki. M. borsoni was a much larger animal which was found throughout Eurasia from the late Miocene to early Pleistocene. It isn’t clear whether it is actually a member of the mastodon genus, or a separate descendant of Zyglophodon. It had very small lower tusks as well as extremely long upper ones.

Mastodon by Heinrich Harder (1920).

Zyglophodon emerged in North Africa in the early Miocene, and spread into Eurasia and North America, before disappearing in the late Miocene. It had long upper tusks, small lower ones, and was probably the direct ancestor of the mastodon.

Palaeoloxodon

Closely related to elephants and mammoths, this genus contains some of the largest and smallest species in the proboscidean order. All of them had two long straight tusks in their upper jaws and resembled bald mammoths or Asian elephants with sloping backs. Their heads were large and had a prominent brow crest which served to anchor the muscles needed to support them.

The first species was Palaeloxodon recki which lived in East Africa during the early pleistocene. From Africa, they spread into Europe and western Asia during the middle Pleistocene as P. antiquus 'the straight-tusked elephant', which lasted until the late Pleistocene on the mainland. Several dwarf species evolved on various mediterranean islands, such as P. xylophagou and P. falconeri on Sicily and Malta, P. cypriotes on Cyprus, and P. tiliensis on the Greek island of Tilos. Some of these survived into the Holocene. P. namadicus grew to immense size in the Indian subcontinent from the middle to late Pleistocene. P. turkmenicus lived in central Asia in the middle Pleistocene, while P. huaihoensis inhabited China from the middle to late Pleistocene. P. naumanni colonised Japan and shrank to fit into the island ecosystem.

One of the earliest elephantimorphs, possibly an ancestor of the gomphotheres, the mammutids, or both. It lived in north-east Africa during the early Oligocene. It had a short trunk, sharp fang-like upper tusks, and scoop-like lower ones. Phiomia was a similar creature which inhabited the same region from the late Eocene to the early Oligocene.

Stegodon had two long tusks projecting from its upper jaw which grew so close together that the trunk could not fit between them. They emerged in Asia during the late Miocene and lasted until the late Pleistocene. Mainland species such as S. zdanskyi, from China, and S. ganesa, from India, were large. Island species, such as S. aurorae, from Japan, S. florensis and S. sondaari, from Indonesia, tended to be smaller.

Stegotetrabelodon

A possible descendant of the gomphophere Tetralophodon and ancestor of elephants and mammoths. It had four extremely long, straight tusks, two closely spaced on the lower jaw, and two diverging on the upper. It emerged in the Arabian Peninsula during the late Miocene, from there it spread into east and north Africa and survived until the early Pliocene.

Gigantopithecus in GURPS

Although known only from teeth and a few jaw fragments, this giant ape has attracted a great deal of speculation. Some even believed it was a human ancestor, although it is now generally accepted as being closer to orangutans. It lived in East Asia from the early to middle Pleistocene.

It seems to have been ground dwelling, like a gorilla, but had a more varied diet including fruit and bamboo. The exact size has been subject to much debate, but it was certainly larger than a gorilla and seems to have had significant sexual dimorphism, with males potentially being more than twice the weight of females. This suggests that they had a harem social structure where a dominant male established mating rights with several females.

Alternative Interpretations

Reconstructed as a collosal Australopithecine, Gigantopithecus would have stood up to 12' tall. Combined with a brain barely larger than a scaled-up chimpanzee, the result is close to the Ogres from Banestorm or Dungeon Fantasy.

Deinotheres in GURPS

Although deinotheres separated from elephants early in their evolutionary history, the two branches of proboscideans evolved in parallel towards large body size. The 'terrible beasts' looked much like elephants, although their ears and trunks were somewhat smaller, thier legs and necks longer, their heads flatter, and their tusks curved down from their lower jaws rather than forward from the upper.

Chilgatherium lived in North-East Africa during the late Oligocene. By the early Micene it had been replaced by Prodeinotherium, which spread across the newly-formed land-bridge to the Middle East and then Europe. During the middle Miocene it evolved into Deinotherium, the last and largest of the family. D. giganteum survived to the early Pliocene in Europe, D. indicum in India died off by the late Miocene, and in Africa D. bozasi lasted to the middle Pleistocene.

For Chilgatherium (3,400 lbs.) reduce ST and HP to 30 (3d trampling damage, 3d−1 trunk damage), SM to +2 (7 hexes), trunk reach to C, 1, and DR to 3. For Prodeinotherium (8,000 lbs.) reduce ST and HP to 40, SM to +3 (10 hexes), trunk reach to C, 1, and DR to 4.

Paradolichopithecus in GURPS

A large monkey found throughout Eurasia during the Pliocene and early Pleistocene. Related to baboons, it had a similar long snout and fangs, but was fully upright, like a human. Several species of its living relatives use simple tools, and with hands free to hold objects, Paradolichopithecus would have been well suited to using them too. Anything more complex than a crudely-shaped stick would probably be beyond their ability to craft, but they might be able to use more advanced weapons if they can get their hands on them.

Ceratopsians in GURPS

An extremely successful group of dinosaurs. They combined deep beaks with mammal-like chewing teeth, making them very efficient plant-eaters. Their skulls were large and wedge-shaped. At first they were small and bipedal, but later evolved into massive quadrupeds. Although all members of the group were herbivores, their strong, sharp beaks would have made it easy for them to dismember other animals and they may have supplemented their diet with carrion or opportunistic kills.

Agathaumas sphenocerus, by Charles R. Knight (1897).

Auroraceratops

A small biped from early Cretaceous China. It had the same sharp beak and grinding teeth as later ceratopsians, but only a small frill and no horns.

Numerous other small ceratopsians were quite similar. Chaoyangsaurus, Hualianceratops, Xuanhuaceratops, and Yinlong were all from late Jurassic China. Yamaceratops lived in Mongolia during the late Cretaceous.

For Chaoyangsaurus, Hualianceratops, Xuanhuaceratops, and Yinlong (12-20 lbs.) reduce ST and HP to 5, SM to −2, and damage to 1d−5 with the beak or 1d−4 with a claw. For Yamaceratops (4 lbs.) reduce ST and HP to 3, SM to −3, change damage to 1d−6 with the beak or 1d−5 with a claw, and remove DR.

Protoceratops

Combining features of smaller ceratopsians like Auroraceratops with those of the horned giants, Protoceratops was a pig-sized animal with a modest frill and small nasal horn. It spent most of its time on all fours, but could run on two legs if needed. It lived in China and Mongolia during the late Cretaceous.

Nesting Protoceratops, by Charles R. Knight (1927).

Protoceratops shared its habitat with Udanoceratops, a larger, hornless creature with powerful jaws for tearing apart tough plants. It was related to Leptoceratops from late Cretaceous Larimidia (now Western North America), which was about the size of Protoceratops.

For Udanoceratops (1,500 lbs.) raise ST and HP to 23, SM to +2 (4 hexes), DR to 4, add Striking ST 4 (Beak Only), changing damage to 2d+2 with either beak or claw, and replace Enhanced Move with Semi-Upright. Leptoceratops (400 lbs.) just adds Striking ST 2 (Beak Only), changing damage with the beak to 1d+1.

Psittacosaurus

The various species of this large genus lived all over Asia during the early Cretaceous. Their overall body plan was similar to Auroraceratops, but they had chisel-shaped teeth and short but powerful beaks, ideal for cracking nuts. Lacking chewing teeth, they relied on gizzard stones to grind their food. They lacked frills, but had spikes on their cheeks. Some of the scales on their upper tails were modified into long bristles or quills. Although their ‘hands’ lacked true opposable thumbs, they did have one digit which was offset and could be used to grasp.

This profile suits the larger species of Psittacosaurus, such as P. amitabha, P. major, P. mongoliensis, and P. sibiricus. For smaller ones such as P. gobiensis or P. sinensis (12-20 lbs.) reduce ST and HP to 5 and damage to 1d−3 with the beak or 1d−4 with a claw.

Triceratops

The famous three-horned monster had a huge head with a relatively small and plain frill. The neck and body were short and wide, while the tail turned sharply downward behind the pelvis. Large scales on the body had short spikes and the toes were capped with hooves. Although often portrayed as a herd animal, there is little evidence to suggest that adult triceratops gathered in groups. Juveniles seem to have stayed with their nest-mates (and possibly parents) for protection though. They lived in Larimidia during the late Cretaceous.

Tyrannosaurus and Triceratops, by Charles R. Knight (1928).

Most other large ceratopsians were distinguished only by size, horns, and frill shape. All of them lived during the late Cretaceous and all were found in Larimidia except for the single-horned Sinoceratops from China. Torosaurus had horns very like Triceratops, but a larger frill with two openings in the bone. Some scientists believe that it is the same genus as Triceratops, reflecting how the frill develops in older individuals. Chasmosaurus also had three horns, but the ones above the eyes were very small and the nasal one only moderately sized. Centrosaurus had a similar arrangement, only its nasal horn was long, and its frill had several curved spikes. Large numbers of Centrosaurus fossils found together indicate that they may have gathered in herds. This is also the case for its relative Styracosaurus, which had a single nose horn and many long spikes on its cheeks and the edge of its frill. Diaboloceratops had just the two horns above its eyes and two long spikes on its frill, as did its relative Machairoceratops. Pachyrhinosaurus had blunt slabs instead of pointed of horns and lived in cold Northern regions. Pentaceratops had five horns, with two sprouting from its cheeks.

For Torosaurus (22,000 lbs.) raise ST and HP to 56 and DR to 11. Change damage to 6d+7 with the beak and 6d+13 with the horns or trampling.

Note: the Reach for the horns has been limited to reflect their actual length. Using the actual rules for strikers they would have Reach C-3.

Zuniceratops

A relatively small dinosaur from Southern Larimidia during the late Cretaceous. It resembled the large ceratopsians in everything but size.

Turanoceratops lived in Mongolia around the same time.

This profile works as-is for Turanoceratops.

Sparassodonts in GURPS

Closely related to marsupials, this order of carnivorous metatherians never left South America, dying off before the ‘great American faunal interchange’ that introduced new mammals to the continent. Like marsupials, they gave birth to tiny young which sheltered in a pouch while they developed. Convergent evolution shaped many of them into near copies of placental mammals. Although most of them walked flat on their feet and were poorly suited to running, many could stand upright to grapple prey.

Borhyaena

Borhyaena was a better runner than most of its relatives, although not to the extent seen in some marsupials and placental mammals. It would have still had to rely on ambush and stalking when hunting, and likely supplemented this diet with scavenging. It lived in Argentina and Chile during the middle Miocene.

Australohyaena was a close relative from late Oligocene Argentina which was both bigger and better adapted for crunching bone. Callistoe was about the same size as Borhyaena but even better adapted to running at the expense of losing some range of motion. Dukecynus is known only from fragmentary remains, but appears to have been similar to Australohyaena. It lived in Columbia during the mid Miocene. Lycopis had a wolf-like snout and lived in Argentina and Columbia during the middle Miocene.

This profile can also be used for Lycopis. For Australohyaena or Dukecynus (150 lbs.) increase ST and HP to 11, SM to 0, and add Striking ST 2 (Bite Only). Change damage to 1d for both bite and claw. For Callistoe increase Move to 7 (Ground Speed 14 with Enhanced Move), remove Bad Grip, Flexibility, Ham-Fisted, and Semi-Upright, and add Quadruped. 

Proborhyaena

A massive, bear-like animal. Despite its bulk, it was an active predator with impressive fangs. It lived in Bolivia during the late Oligocene.

The closely related Paraborhyaena, also from late Oligocene Boliva, was almost as large. Arminiheringia wasn't closely related, but rivalled Proborhyaena in size and had similar anatomy. It lived in Argentina during the during the early Eocene.

For Paraborhyaena (250 lbs.) reduce ST and HP to 13. For Arminiheringia change bite damage to cutting.

Thylocosmilus

A saber-toothed predator which took it to an even more extreme level than Smilodon. Its mouth could hinge open wide enough to stab its oversized fangs straight into even the largest prey. These huge teeth were rooted above the eye-sockets and wrapped half-way around the skull. The lower jaw had flanges to protect the tips. In overall body plan it mimicked the dirk-toothed cats, with strong fore-legs for grappling. It is known from Northern Argentina during the late Miocene and early Pleistocene.

Anachlysictis was a smaller relative from middle Miocene Columbia.

Oxyaenids in GURPS

A family of early Paleogene predators, distantly related to hyaenodonts and carnivorans. They resembled mustelids (weasels and badgers) with some cat-like features and long, thick tails.

Machaeroides

One lineage of oxyaenids developed dramatic fangs, much like the saber-tooth cats. These were protected by a bony flange under the chin, and likely sheathed themselves in long lips. The earliest known, Machaeroides, was around the size of a wolverine and lived in North America during the early Eocene. It was succeeded in the middle Eocene by the leopard-sized Apataelurus in East Asia and North America and the fossa-like Diegoaelurus in California.

Oxyaena

A wide-spread genus, known from Asia, Europe, and North America during the early Eocene. Resembling an otter or wolverine, it seems to have been a highly adaptable generalist, consuming carrion, fish, small animals, fruit, and roots. It was preceded in the same territory by the rather similar Palaeonictis, which lived from the late Palaeocene to the early Eocene.

Patriofelis

An early Eocene North American genus consisting of two species. P. ulta was a little larger than a lynx, while P. ferox was intermediate in size between a cougar and a lion. They had stiff spines, which would have made them sturdy but inflexible.

Sarkastodon

The largest known oxyaenid lived in East Asia during the middle Eocene. Known only from its skull, it is usually reconstructed as resembling a bear with short legs and a long tail. Unlike a bear, it was a hypercarnivore, eating only flesh. Its size suggests that it would find running difficult, so would have to rely on ambush and scavenging.

Rauisuchids in GURPS

Unlike their crocodile relatives, these triassic monsters were warm-blooded and hunted on land. They were common throughout the Triassic and lived in all the warm regions of Pangaea. All of them had large heads, slicing teeth, thick necks, straight tails, and four legs which were positioned under the body. Rauisuchus itself was a fairly average member of the group which lived in the arid regions of Western Pangaea (now the Americas), as was Vivaron. Vivaron's close relative Teratosaurus was significantly larger, as were Postosuchus and Polonosuchus, all of them inhabiting the wetter regions in North-Western Pangaea (North America and Europe). Scolotosuchus, on the other hand, was smaller and more agile, and lived in the coastal plains of Northern Pangaea (Russia).

Phytosaurs in GURPS

Although only distantly related to crocodilians, phytosaurs looked almost exactly like them. The most noticeable differences were that the ends of their snouts curved down and their nostrils were positioned near their eyes. All known genera are from the late Triassic, although they are believed to have evolved near the beginning of the period. They lived in the tropical regions of Pangaea.

Angistorhinus

A large phytosaur with narrow jaws and slender teeth, ideal for catching fish. Rutiodon was similar in both size and diet, while Machaeroprosopus was a smaller fish-eater.
