| 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!

You know the new canadian istiodactylid Gwawinapterus? It seemingly dates about as recently as 75 million years ago. You know where this is going. |

Doesn't surprises me at all that adaptable and advanced creatures such as pterosaurs didn't decline much, the things pretty much took all niches large birds take today, Storks, Ground Hornbills, small seabirds, large seabirds, nocturnal birds , they did even took some niches left by insectivorous bats. Some people saying birds were more efficient and replaced them is just stupid anyway |

Well, you gotta consider that there was an extinction between the Jurassic and Cretaceous that caused a serious decline in the pterosaur population, allowing birds to diversify and take most of the small pterosaur niches. |

It would be good to name an American istiodactylid the 'Jersy Devil' :lol:. Well, but it seems that in late cretaceous pterosaurs pretty much recovered. Liks Austroraptor said, azhdarchids and such pretty much dominated the large bird niches and there were anurognathids in late cretaceous as well. |

This is going into my fantasy project. |

I do art sometimes. "if you want green eat a salad" Projects: Amammalia: A strange place where mammals didn't make it and the land is, once again, dominated by archosaurs. Oceanus: An endless sea dotted with islands, reefs, and black holes. Literally endless, literal black holes. ❤️❤️~I'm not a boy~❤️❤️ | |

Projects and concepts that I have stewing around Extended Pleistocene- An alternate future where man died out, and the megafauna would continue to thrive (may or may not include a bit about certain future sapients) Inverted World- An alternate timeline where an asteroid hit during the Barremian, causing an extinction event before the Maastrichtian. Dinosaurs, pterosaurs, and notosuchians make it to the present, along with a host of other animals. Badania- Alien planet that has life at a devonian stage of development, except it exists in the present day. Ido- Alien world where hoppers (derived flightless ballonts) and mouthpart-legged beasts are prevalent. Leto- Life on a moon orbiting a gas giant with an erratic orbit; experiences extremes of hot and cold. The Park- ??? Deeper Impact- a world where the K-Pg extinction wipes out crocodilians, mammals, and birds; squamates, choristoderes, and turtles inherit the earth. World of Equal Opportunity- alternate history where denisovans come across Beringia and interact with native fauna. Much of the Pleistocene fauna survives, and the modern humans that end up crossing into North America do not overhunt the existing animals. 10,000 years later, civilizations exist that are on par with European and Asian societies. The Ditch- Nothing is what if seems.. | |

Eh, not as much as you think. My paleontologist friend mentioned something to me about this, but I forget what he said and need to get permission to post it. |

So you need permission to include the new istiodactylid in a spec evo project? That's creepy. |

No, just to confirm whether or not azhdarcids and other pterosaurs really did make a come back over birds during the late Cretaceous. |

Oh crap. I'm just keeping azhdarchids in my project no matter what Canis's friend says.

I don't think bird competition would be much of a problem for azhdarchids, though being large animals would make them more prone to extinction. |

That is extremely inconsistent with what we know. Cretaceous pterosaurs were extremely diverse in the early Cretaceous, which is odd if they were supposed to have faced extinctions. In any case, some time ago I mentioned the non-pterodactyloid pterosaur remains found in Argentina, before I found about this istiodactylid. Maybe one day someone will find a Cenozoic pterosaur, who knows. |

Johnfaa's right. If there was a really pterosaur-killing extinction, that doesn't explain the diversity of pterosaurs in Early Cretaceous. There were Tapejarids, Dsungapterids, Istiodactyloids, Ornithocheirids, early Azhdarchids etc. |

This... has been known for ages? I've never heard that pterosaurs were facing extinction during the late mesozoic. |
