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 had this idea in the car of what if some aalien overlordic race took several pterosaur species and relocated them on another planet. These are the species that might work:
Posted Image
Hatzegopteryx
Posted Image
Dimorphodon
Posted Image
Anhangueara
Posted Image
Pterodaustro
Posted Image
Nyctosaurus
Posted Image
Tapejara
Posted Image
Dsungaripterus
Posted Image
Pteranodon
Posted Image
Anurognathus

I have several ideas for creatures. Of course all normal non-tetrapods and amphibians that existed in the late cretaceous were also brought over.

Question: As Dimetrodon hips suggest it may have been the only pterosaur able to walk on it's hind legs (bipedally) could it evolve permanent bipedalism rather than just for short periods of time?

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.

But it would be better for pterosaurs to swim in a more hesperornithe way, they could lose their wing membranes freely and as a result they would be more cold-resistant, better for insulation.

And FW, if you weren't such an ignoramus you would have seen that fish and invertebrates as well as non-archosaur reptiles were brought too.
Care to check your own posts.

Your ad hominem is appreciated.
Well, I have to agree with Jason, you're just being an idea snagger this time FW. The point of a Terraforming project is to have Earth life transplanted in an alien planet, just to speculate on how they would evolve in interaction with each other in an alien environment. And in most cases, the more basal Earth life, such as fish and invertebrates, are already transplanted, unless there is a clear notation that they weren't.

And life evolves, they probably won't just starve to death in a terraformed planet. That's just stupid, to put it in a nice way.

As for Pterodaustro descendents becoming baleen whale like, yes, its possible. Unlike birds, it appears pterosaurs could develop vivipary.

Your misinterpreting what I mean: pterosaurs' role in the food chain means that you need to bring so much that you just get about the same thing as earth or they starve. They eat Everything, but plants.

Why can't they evolve to feed on plants?

So that they can become ratite analogues?

Actually it would be more like ungulate analogues, but they can. FW doesn't know what is going on. Hypercarnivorous pterosaurs could eat other pterosaurs and without much competition, the land would be filled.

Yes, by ratite analogues I also meant tall-browsing ungulate analogues, but smaller deer-sized forms could also arise.

And Hatzegopteryx would probably be apex predators.

Yup. And the dsungaripterids will be like smaller hunters, thanks to Rick's suggestions.

Sense when?

The largest pterosaurs need archosaurs or they will starve in the short term.

Pterosaurs lack the stomach to deal with plants, and by the time they could the role would be filled by one of those non-archosaurs that developed it several times.

we dont have stomach of pteranodons o_o

i agree wtih you on the dirst point.Hatzegopteryx would die shortly after introduction.It would be like introducing tigers to enviroment,where lives only small rodents

They appearently had crops. And their beaks are not really suited to do anything other than a ratite style diet really; they are often too short when compared with the rostrums of similar taxa that were small tetrapod eaters (azhdarchids, chaoyangopterids), and their biting force was significantly weaker, suggesting that they weren't going after prey that was any bigger than small lizards and mammals.

Therefore, it makes more sense that they were cassowary like frugivores, fungivores and folivores, eating small animals as well but not feeding exclusively on animals.
