| 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.

What if all non-avian dinosaurs didn't die out? After Dougal Dixon's famous book The New Dinosaurs: An Alternate Evolution many different people have asked that question. I will try to answer it. Anybody who wants to is welcome to join. I'm a pretty crappy artist so I will probably need the assistance of 1 or 2 artists. Timelines will be available if you guys request. |

Alright, here's what i found. And i've been spelling cretaceous wrong, sorry.
For mid cretaceous turbulences,
Sorry if that's a bit long, it's just the last few sentences neede. He's saying there were long term changes in the nutrients of the mid-cretaceous seas.
But we all knew about volcanism in the cretaceous anyway. It has been proposed as a contributing factor to the extinction. |

Where did you got this exactly? Because some of the information is either outdated or misinterpreted; in Solnhofen there were only 1 bird and several pterosaur species (neither group was very numerous, but pterosaurs outnumber birds a lot). Second, there are actually more pterosaurs occupying seabird niches than birds themselves, most associated with diving, something pterosaurs were incapable off. Thus, we have Itchyornis+Gansus+some other random bird vs many genera of Ornithocheirids, Pteranodontians and some Ctenochasmatoids, thus outside of diving niches birds did not control niches now occupied by seabirds back then.

They found a compsognathus at solnhofen, but the place was underwater, wasn't it? Well, i got it from a sciencey website, but i wouldn't be surprised it they had misinterpreted something. Edited by Holben, Nov 11 2009, 03:24 PM.

Compsognathus isn't a bird |

I know, it's a small theropod dinosaur. I was wondering how it got there. Maybe it was washed out by a flood. |

Back then, Solnhofen was an archipelago in a shallow lagoon. Said lagoon was so shallow that it had a lot of evaporation taking place, and since little to no rain was there end up up have very salty waters, in which animals could easily die in and being very well fossialised, since no animal was that stupid to try to eat a poisonous fish corpse. Sadly, Compsognathus was, and thats why we know they existed, because they went to eat fish poisoned by the salt and died as well. The kind of environment that Solnhofen was probably benefited pterosaurs as lot more than dinosaurs. For one side, we have pelagic rhamphorhynchids that probably layed there eggs there like modern sea turtles and petrels do on isolated islands. Then we have various species of coastoal pterodactyloids like Pterodactylus, Cynorhamphus and Germanodactylus feeding on invertebrates and small vertebrates that the islands were rich on, with filter feeding Ctenochasma feeding on brine shrimp and Anurognathus flying in search of insects. By contrast, the only dinosaurs were a small coelurosaur and a midget bird |

Well I am glad the people here don't hate Bats and I do understand alternate groups being fun, the point I was trying to make was that those new groups always turn into Bats when they should be unique. And the only thing I will say about the Pterosaur discussion is that it sound like Pterosaurs could have recovered with out the K-T event. |

Like or not John, pterosaurs were in decline at the end of the Cretaceous. Only a hand full of species are known from that time. And as for anuragnathids surviving to late Cretaceous, who's idea was that, I mean what proof is there to support that? |

Look, I've been explaining millions of times why pterosaurs haven't been in decline since the late Cretaceous. There's even papers about that. And the Maastrichian has a very poor fossil record in general. So, please do some research on this forum. I'm fucking tired of pointing out the same things over and over again, so don't be stupid and look at older posts and everything |

Oh, and by the way, I did this post a long time ago: http://s1.zetaboards.com/Conceptual_Evolution/topic/1399565/ It was to end with this pterosaur decline nonsense. Appearently it didn't work. I honestly don't know if it is because of the media, because of the development of the brain of the people here who are claiming pterosaur decline or because everyone is loves dinosaurs so much to the point of bestiality that they ignore any news on other prehistoric sauropsids |

Alright, we're past that now. How would these bats manage to evolve? Birds and pterosaurs would compete with them... but maybe less for nocturnal slots, freeing them up time. Well, most mesozoic mammals were probably nocturnal. |
