Trilophosauria
Trilophosauria, in our timeline, is an order of medium sized Triassic diapsid reptiles specialised for eating plant matter. Like many other families they died out with the T-J extinction.
In the DW timeline, they survived, and flourished. From sprawling lizard like animals, they have evolved into swift, erect stance animals more closely reminiscent of the lighter ungulates, especially cervids, antelopes, bovids and equids.
No one is entirely sure how this happened. Certainly, some showed signs of being capable of semi-erect stances, but there is an infuriating lack of discovered Trilophosaur fossils between mid-Jurassic and early Pliocene. Further excavations needed.
Nevertheless, they have gone from strength to strength, taking myriad small-medium agile herbivore niches across Afro-Eurasia and the Americas. Australia, being weird and different as normal, has no species of Trilophosaur, relying on tortoises and ostrich-crocs instead.
Copper Deer (Aeneosauridua)
The most widespread group, found in Eurasia and America, mostly as small-medium browsers and grazers in forests and plains, though with some large specimens in other areas, such as the Scandinavian Selamodir and the British Ireler
Saurozelles (Dorcasauridae)The majority group of small herbivores found in Africa, India and China. Generally smaller than Copper Deer. Mostly relatively small and herbivorous
Hupdalopes and Bossaglers (Bovisauridae)
A mostly African and Indian group comprising large grazers, the only Trilophosaurs to come close to rivalling any of the Aetosaurs. Includes the various 'vocal' Trilophosaurs as well, not to mention the Sauraffe.
Giant Hupdalope (Hupdosaurus Giganticus)
The largest of the Hupdalopes, reaching up to around 12 metres in length, and the first one to be formally named, Giant Hupdalopes are found across sub-Saharan East Africa. Males and females both sport a small domed crest with a pair of horns that sweep back across the dorsal ridge. As in all Hupdalopes, female horns are smaller. The crest is used for communications within the herd, but their sounds are not nearly as complex as in other Hupdalopes. They are heavily built, with a rather unique drab brown colouring, with their undersides patterned with dark stripes. They are not fussy herbivores, eating whatever plant matter they can digest, which includes the softer grasses and most browsing fare. Their herds are small, containing one dominant bull and several cows, plus young. Dominant bulls ward off potential challengers with displays of aggression such as stamping and furious head-shaking. The females of a herd work together in nest building and caring for their young, who normally leave the herd at around five weeks old.
Pruxes (Proxiceridae)
A rare and undiverse group containing only five species spread across the Balkans, the Dardanelles and the Bosphorus, mostly smallish, lightly-built herbivores with large and elaborate animals
