Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

I just realized this has some crurotarsians in it, like in TA. Whoops. Soz JF

Aetosauria - Elephant/Pig like forms
Phytosauria - Crocodiles
Prolacertiformes - Small scavengers, except for Shavopteryx descendants, and isolated large creatures
Rauisuchia - Big carnivores, and some gallimimid like forms
Rhynchosauria - Hippo like creatures
Trilophosauria - Ungulate like life forms
Younginiformes - Lizards
Avicephala - Bird like, chameleon like in some forms
Thalattosauria - Sea-lizards
Sphenosuchia - Most non volant arboreal carnivores

I'll get some work started on this soon. If anyoone would like to help, just ask.

I wasn't really gonna give em trunks. Just make em big and stompy. A few might have trunks though.

I'm working on a design for Wyverns, the Shavopteryx descendants. Would the be able to walk on their back legs still?

I think so; will avicephalians be literally bird-like (that is, with feathers and such), or will they have leathery wings?

Rauisuchia family outcomes
Prestosuchidae-extinct, Rauisuchidae took outcompeted them.
Rauisuchidae-top predators in most places except on some islands where phytosaurs/thalattosaurs/prolacertiformes got there first. Family includes
Diamond Dogs-Adamosuchids-(land based)mustelid/canid/felid/etc... forms.
Sobeks-Petsuchidae-Ursid/larger felid forms
Dreadnaughts-Ubersuchidae-creatures comparable to the dinosaurian carnosaurs.
Poposauridae-ostrich-crocs only
Ostrich-crocs-Cursosuchidae-Ostrich/ornithomimid like crocodiles.
Ctenosauriscidae-Extinct

In this, the only extinction event that didn't happen was the Triassic Jurassic. K-T happened, the ice ages came, and the Haughton comet did collide. There are two major places where Raiusuchids never got a hold. Greece and the British Isles. Both are ruled by Avicephalids and some tanystrophen-esque predaators

EDIT
All geographical based entries shall be posted here.

A little synopsis on the island of Majorca

Whilst many of the islands can boast truly a magnificent display of fauna, few in Europe can best that of Majorca. Britain is similar to mainland Europe's despite the Ctenosauriscidae predators, Sciliy shares much with Italy, and even the bizarre fauna of Greece and nearby islands are rather uniform to that area. Majorca, and many other Balearic Islands can show truly magnificent examples of evolution. Minorca for instance has main predators displaying similarities to African griffons, alongside small apelike bat-likes in the trees, and strange aquatic Pseudornids who act like rabid swans.

Majorca however, has the most amazing of all of these.
Present on the island are example of Raiusuchids, Sphenosuchids, Rhyncosaurs, Dinosaurs, Drepanosaurs, Mammaliformes, and Phytosaurs.

The Raiusuchids are represented by only one member: The Dwarf Mallorcan Ornlu. Despite being a midget compared to its many close cousins, it is the largest and most powerful truly terrestrial predator on the island, capable of bringing down the large Rhyncosaurs and herbivorous Drepanosaurs and Mammaliformes of the island. Compared to their worldwide cousings, Ornlus are very lightly built, and are desgined for speed and manouevrability, sacrificing some of the stamina and durability of their relatives. Nevertheless, in amongst the thick forests and open maquis that make up the most part of the Mallorcan landscape, these are incredibly important abilities to have. They have been found on the lower parts of the mountains, but these are normally the realms of the Tramuntanan Dragon, other avicephalids and several little sphenosuchids. Beach-combing is not unnatural either. Normally reaching about 1.2 metres at the shoulder, and about 2.6 metres long, they are typical of Ornlus in their intelligence and hunting-pairs, and have been seen setting up ambushes; one driving smaller Rhyncosaurs back to their burrows whilst the other lies in wait before leaping out and killing it. The only real danger to them, besides angry Mediterranean Scaleswine, are the Insular River Beasts that plague most of the Med.

I know, nobody posts in either of my projects.
Well, most of the neotanystropheids are venomous (makes Hydras and Questing Beasts more likely)
Ostrich-crocs include some therizinosaurid-esque beasts

EDIT
All entries on carnivorous non-avian reptiles will be posted here.

Ornlus

Kingdom: Animalia
Phylum: Chordata
Class: Sauropsida
Subclass: Diapsida
Infraclass: Archosauromorpha
(unranked): Crurotarsi
Order: Rauisuchia
Family: Rauisuchidae
Subfamily: Adamosuchidae
Genus: Ornlu

The Ornlus are one of the genii of modern Rauisuchids. They are the largest (on average) genus of the 'Diamond Dog' Subfamily, and are the most single widespread genus of Adamosuchids in the world, with species present in Japan, Britain, Greece and even the New World. Like all Adamosuchids, they are warm-blooded and lay eggs, the number depending on the species. In many cases, they are an Apex predator.

The genus includes, in order of descending size
Mongolian or Khannic Ornlu
Teutonic Ornlu
Hunnic Ornlu
Aztec Ornlu
Mayan Ornlu
Persian Ornlu or Mahoudile
Gothic Ornlu
Turkish Ornlu
Arabian Ornlu or Saladin's Ornlu
Chinese Ornlu
Korean Ornlu
Scandinavian or Viking Ornlu
Frankish Ornlu
Spanish Ornlu
Byzantine Ornlu
British Ornlu
Japanese Ornlu
Celtic Ornlu
Various sub species of Mediterranean Ornlu.

Khannic Ornlus generally grow to a maximum 8.7 metres. The smallest species of Mediterranean Ornlu, the Dwarf Mallorcan Ornlu grows to maximum 3.1 metres

Ornlus are exclusively carnivorous and are long distance runners, normally hunting in small packs or pairs. A common strategy is to flank their prey and prevent it running off to the sides. They will happily run prey into the ground, before ripping it to shreds with their teeth. The Persian Ornlu is the fastest whilst the Gothic is the slowest. Most Ornlus are rarely scavengers, and do not eat food older than four days, though the Hunnic and Scandinavian Ornlus are much less fussy, happily driving off Skoffins and Urdakotturs, in the latter's case, or Quartzhounds and Armourbears in the case of the former. Prey differs depending on country and habitat, but mostly it is made up of Trilophosaurs and Ostrich-crocs, but some will attack Rhynchosaurs or smaller Aetosaurs. On occasion, one may be lucky enough to catch a herbivorous Avicephalid.

I just realised that in this world there are no birds, and no feathers! Now I just need to get rid of mammals, than I have a perfect world.

All herbivorous reptilian non-avian entries shall be posted here.

True, a sauropsid only world. You might need to think very well in order to kill mammals and leave the sauropsids though...better to just say they died for no appearent reason XD

Nah, I'm gonna keep mammals. Mainly they will just be bats and squirrels.

EDIT
All mammalians and dinosaurs (avians) will be posted here.
