| 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 first thought I could do this project, but I'm actally concentrated in my Lost Island one, so if anybody wants to take it, that's fine. In this world, the Aptian extinction never happened. For the ones that don't know this extinction, it's not as big as the P-T or the K-T, but this was what basically screwed pterosaurs. Fossil records show that after the Aptian most pterosaur families dissapeared, leaving only pteranodons and azhdarchids. So, if this extinction never occured, probably birds would never diversify, and probably pterosaurs would be able to survive K-T, but what do you think? |

I'm a little shaky on the Aptian extinction, all I know is that it occured in the Cretaceous and mainly affected marine life. Are people sure this contributed to a decline in pterosaurs? |

Well, yes, as on land groups like spinosaurs and non-titanosaur sauropods were already on the march to extinction. However, this single event did not reduced the pterosaurs so much; forms like lonchodectids and ornithocheirids still lived well into the Cretaceous, and anurognathids are theorised to have survived into the late Cretaceous as well. |

This sounds interesting. Though I have never heard of the extinction so what it changes I have little clue? |

Dodo is right. This extinction affected mainly marine life, and pterosaurs were also affected, and some scientists theroize that this might have contributed to the later extinction of all the pterosaurs, but this is mainly a theory. |

Basically that the extinction didn't occured only on marine environments, and in any case most pterosaurs weren't even aquatic prey eaters anyway. |

Once again, my naivity shows, but I was under the impression that the majority of them ate fish or cephalopods. Please, JohnFaa, enlighten me. |

Mind that it was before the discovery of Darwinopterus, ence my then ignorance towards aerial predators. Even though Pterorhynchus had already been found... |

Thanks. I really need to bone up on my prehistoric life (there's a pun in there, somewhere...) So, if this extinction never happened, birds never became successful, and the pterosaurs have taken their place up until the Homocene, how might this affect mammalian evolution? |

Most likely mammals would have had more serious competitors, as pterosaurs are quadrupedal too and unlike birds their egg shells are quite thin, meaning ovovipary could be achieved |
