| 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. While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself!

**NOTE** I am not going to update this very often, only when I have a creature. It's been bugging me for a while and I want to get this out. Also, I am borrowing a lot from my old Alternative KT Extinctions project. In this project KT was not an asteroid but instead volcanic eruptions that weren't as devastating as the real KT. After the KT extinction the world was dry and hot and had lower oxygen levels, a mammals hell. Mammals were one of the hardest hit organisms, with only a few metatherians surviving in North America and Gonwanatheres surviving in South America, which were the least hit continents. Amphibians got totally wiped out. Neornith birds got a devastating hit as well. The extinction also killed off all aquatic and semi-aquatic tetrapods, leaving the seas empty for millions of years. Fish took hold, only allowing a few spots for new incoming tetrapods. Sauropods were eliminated in the extinction, being the largest animals on Earth. Pterosaurs also went extinct. Enantiornith birds are the dominant flyers, looking like feathered pterosaurs. They take dominance like the birds of today and the Neornith birds take a dominance level of bats. Hadrosaurs were the only surviving group of ornthipods. Theropods were hard hit by the extinction too and were reduced to only dromaeosaurids, troodonts, and therizinosaurs surviving. They never regained their dominance except in Africa, and during the Oligocene Cooling the feather insulation of the therizinosaurs allowed them to dominate over their naked cousins. In Laurasia hadrosaurs became the dominant herbivores except in North America, in which Pachycephalosaurs became dominant. Eventually the hadrosaurs and pachycephalosaurs became more fit for being the fast and fast reproducing prey animal, while ankylosaurs and ceratopsians became the bulky prey. The Laurasian predators started out to be the theropods again, but some pachycephalosaurs became predators (they were already omnivores). They first became dominant in North America, but 30 million years ago when the landbridge first appeared between North America and Eurasia they crossed over to the Old World and pushed out the carnivorous theropods. Gondwanaland became dominated by notosuchians and secondarily by birds. The notosuchians grew a variety of forms, from giant sauropod-like forms to aquatic forms to giant carnivore forms and a whole lot of other forms. They were originally just in the southern continents until some Indian notosuchians crossed into the Old World. Close to present day more advanced ones came from South America and Australia, and really began their world dominance. Ceratopsians were really the only Laurasian life to gain a hold in South America. Pachycephalosaurs and theropods tried to gain dominance but didn't make it and are on the brink of extinction in the southern continent. On a smaller side, Gondwanatheres remain restricted to South America and Australia. Metatherians start moving into Asia, and have competition from squamates. Okay, I'm done now. Took an hour or so to write that up. 4 species coming tomorrow! |

This looks really interesting, looking forward to the four species you will be posting. The descriptions of some types of animals, are those in a modern-day perspective, for example you say ceratopsians are dominant in South America, and other animals are on the brink of extinction - is that modern day times? |

Yeah, most of the descriptions are from modern day. Sorry if I didn't make it clear, it seemed clear when I was writing it up, but now that I look at it I can see how the description will be confusing. The species are going to come in a few hours. Unfortunately they will just be lineart since I don't know what to paint them in GIMP. |

Got the 4 species ready. I'm using Google Translate for the Greek.
Wow, long post. Took me a lot to write this up. Hope you enjoy it

As I said I won't be updating this often, but more will come soon. Probably a ceratopsian. |
