| 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.

In this project everything goes along the same as HE until KT (I know its a popular one). It all goes along the same as it does on Earth, except that there are different victims and survivors. I will do the sea creatures in a few days. Here are the extinct creatures: All anapsids (it includes Testudines). Squamates. Sphenodonts. Choristoderans. Crocodylmorpha. Neognath birds (Modern birds). Non-avian theropods. Sauropods. Ornthipods. Ankylosaurs. Monotremes. Eutherian (Placental) Mammals. Gymnophions (Caecilians (Amphibians)). The surviving animals (To the right is where they are found after KT, but spreading does occur later on): Azhdarchids (NORTH AMERICA, ASIA, EUROPE, AFRICA), Ceratopsians (NORTH AMERICA, ASIA), Pachycephalosaurs (They pwn, wonder why nobody knows of them) (NORTH AMERICA), Ornithocheirods (Used to live nearly everywhere, but by KT restricted to EUROPE), Pterodantids (NORTH AMERICA), Opossums (SOUTH AMERICA), Late Cretaceous Antarctic Marsupials (ANTARCTICA), Stagodontid Marsupials (if you don't know what it is, watch this and pause at 0:40) (NORTH AMERICA), Asiadelphere Metatheres (ASIA), Deltatheroid Metatheres (NORTH AMERICA, ASIA), Enantiornithes (NORTH AMERICA, SOUTH AMERICA, EUROPE, ASIA), Hesperornithes (NORTH AMERICA, EUROPE, ASIA), Paleognaths (SOUTH AMERICA, AUSTRALIA), Cimolodont Multituberculates (NORTH AMERICA, ASIA, EUROPE), Gonwandatheres (Semi-aquatic burrowing beaver-like allotheres) (SOUTH AMERICA, AUSTRALIA), Salamanders (NEAR-WORLDWIDE), and Frogs (NEAR-WORLDWIDE). **NOTE** I'm not counting paleognaths and gondwanatheres in Antarctica because they will die off in Antarctica with no survivors by present day. With the marsupials they will enter Australia like present day after KT happens. KT world: ![]() This project is OPEN, so anyone can contribute. I would like to focus on Present day and 50 million years future. Species format: Name Ancestor: x Time: Present day or 50 MYF. Size: x Behavior: Solitary or group behavior. Area: The area of the continent that they live in. Then go on with the description, and if you have one at the bottom post a picture of it. Present day map (just in case you need it): 50 million years future (note, it is actually a link, not a picture. Just click on it to see the map, but don't take any animals on that website seriously). 50MYF Again, this project is open, so I would really like contributions.

Who said ovivipary was better than eggs? And in enantiornithes most had teeth and 3 fingers (outside the wing). Like Enantiornis. And bipedals are more agile in a case of trying to dodge the horns of a ceratopsian while trying to get its back or young. And theres also the case that the fauna is way different from North and South America in alternate KT. In North America there are ceratopsians, pachycephalosaurs, and maybe giant metatherians and possibly herbivorous pterosaurs. In South America it is birds and opposums. The pterosaurs are adapted to North America, Enantiornithes adapted to South America. |

This is an error so common it almost makes me cry. Enantiornithes, like Euornithes, had two of their fingers fused; at most there'd by two wing claws, as in modern birds. Also while some enantiornithes had teeth the most derived Cretaceous group might had been toothless; the only member with a complete rostrum, Gobipteryx, was toothless |

They could have wing claws, though I would imagine they wouldn't be used for more than perhaps a stabbing motion. |

Wow. I'm going to start working for a South American ceratopsian, and maybe a pachycephalosaur and/or a flightles azdharkid. |

Okay, Someone needs to vote mosasaurs or plesiosaurs, they're tied. I've got 2 species. Nulluptero: A 13 foot long flightless pterosaur, it lives in Asia. I can't draw a picture of it, but I found one that is similar to it. ![]() Headbutter: A 15 foot long Asian pachycephalosaur, it is shaped like an ornthopod, no longer bipedal. It came to Asia from when Asia and North America were connected in the Oligocene. I think I can draw it, but I don't have any image right now. |

Nice pictures. I've already voted, so can't break the tie. What niche does the pterosaur fill? |

Yeah, the flightless azdharkids took the role of large carnivore because any mammal could do so (besides South America and Australia). |

But they were already small. Same thing happened on HE in the paleocene and in some places the eocene (birds took the niches). |

i agree with that,but from small marsupials in south america evolved many species of relative big carnivores(but main predator was terror birds,but many species of them came extinct after invasion of north american mammals) (see sprassodonta)

The terror birds didn't fill all the niches like carnivora does today. That allowed the Sparssaradonts to live. But when carnivora came they competed for ALL the niches, which brought the extinction of both the Sparssaradonts and the terror birds. |

Actually, phosphuracids lived for quite a while after the migration. They found a scavenger niche mainly. |

And when humans came they took that niche, and killed the terror birds. But no humans in alternative KT. |
