| 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.

Land crocodylomorphs like Protosuchia and Notosuchia were the main competitors of mammals during the Cretaceous. At the KT extinction the mammals survived and the Protosuchians and Notosuchians died off. But what if it was the other way around? I might be interested into turning this into a project if enough of you are interested. --EDIT-- Birds are also extinct to allow the crocodylomorphs to take over the world in the Paleocene.

Yeah, they only existed for about 100,000 years into the Cenozoic. But I can imagine duck billed hadrosaur crocodylomorph mimics, after all there were some duck-billed crocodylomorphs. |

As for herbivores here's some things that could work. Quadrapedal herbivores with teeth adapted for eating plants or a mouth with a beak at the front and teeth in the sides of the jaw. Teeth could be flat and grinding, scissor-like, or chisel-like.

Yeah. How long do you think the Protosuchians would survive until they are outcompeted by Notosuchians? |

there is fossil of hadrosaurs that maybe survives into early cenozoic,like pterosaurs about i write..but maybe it is only fossils that were moved by water etc. |

They were fossils moved by water from earlier deposits |

And I never heard of pterosaurs past KT. Only hadrosaurs. Is anyone going to abandon this and answer my question? |

No, about how long the Protosuchians would last against the Notosuchians. |

Because they made the mammalian rise difficult. Without them the world is basically handed over to the crocodylomorphs. |

So the birds just disappeared? Or were they outcompeted by their bigger, slower, flightless cousins? |

but HOW? They never went extinct when the mammals were the dominant form. How would crocodilians rising to power make things different? The only thing it would prevent (most likely) are any flightless or terrestrial birds for a while. |
