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.

Dinosaurs eat man, woman inherits the Earth.

Dimetrodon was a synapsid in the Permian with a giant frill on its back. It was not a pterosaur.

None of those are species and there is little time overlap.

Your Tapejara is a Tupandactylus.

Sorry spellcheck. Dimorphodon.

@FW-Ok, so then i will change the thing to tupandactylus. I know they are not species, but i have a real life and didn't want to look up all the species within the genera so i put the genera for all species within the genera. There is no time overlap, true, a hypothetical alien time traveller did it. I don't realy care how they ended up on the oter planet just what happens.

BTW, this is a terraforming project on a world like late cretaceous earth

Whoa, ouch jasonguppy. Of course, i have a life too, you know. Thats why i was off all this time.
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..

They all starve for lack of food, you can't bring just one group that only eats meat.

Its thare. 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.

If only those pictures weren't horribly out-dated...

More seriously, though, Dimorphodon's supposed bipedalness turned out to be ficticious. However, an aquatic pterosaur could become a biped, as pterosaurs appearently swam using the hindlimbs, so a specialised aquatic form could develop stronger hindlegs.

OK. Yeah, sorry about the horribly outdated pictures, i realized that too, i just needed to show the basic bauplan.

I´d say Tupandactylus could evolve into a herbivore. Its short robust beak doesn´t seem to be adapted for eating fish, but it would crack open nuts and fruits without many problems.

Hatzegopteryx could become one of the apex predators, like a giant four-legged Terror Bird. The Dsungaripterus could evolve into something similar, too, but more robust and with stronger jaws and teeth.

Nyctosaurus could become a flightless swimmer (swimming with its hindlegs like Hesperornithids as opposed to penguins "flying underwater").

Anurognathus could fill the niches of insect-eating birds and bats, and the biggest species might even become owl-like.

That is actually the start I had in mind. As JohnFaa said, maybe some of the aquatic nyctosaurs become bipedal. I'm thinking of looking at the world 90 million years after the relocation.

Well, in regards to bipedal aquatic pterosaurs, what we know about swimming pterosaurs mostly comes from ctenochasmatoids, which were the pterosaurs mostly doing the swimming (being aquatic heron and flamingo analogues).

Since nyctosaurs had weak hindlimbs and strong wings, maybe actual pterosaur penguins could evolve from them, although to do so they need to have no competitors, as fixing the problems caused by heat loss via wing membranes takes time.

Would the Pterodaustros become like Baleen Whales perhaps?
