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! Registration is free and instantaneous.

By Mark Witton. I had similar thoughts, but I must say the idea of a jaçana like azhdarchoid never occured to me, presumably because I think ctenochasmatoids could more easily produce something like that.

Sharks in the linage of the modern great white were already around in the late Cretaceous, so they were obviously present in the Eocene. Also note there were dyrosaurs around, and yet that didn't stop whales from evolving

Um... I'm not an expert here, but I'm fairly positive there was enough time between KT and the evolution of proper cetaceans for the large shark population to recover.

And why couldn't whale pterosaurs start out in rivers and lakes?
Welll- yeah, i suppose so. But my second point still stands. ^_^

These pterosaurs would have flippers to start with, yes? The depth of a river really doesn't work with fins. Webbed limbs, yes, but not fins.
Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea.

The lank is an impossible pterosaur. It is a GIRAFFE! It is not a giraffe-like reptile, it IS a giraffe.

So someone covered a giraffe in scales and gave it a beak? That's bad.

A hadrosaur-beak.

That´s even worse.

It's a reptilian giraffe with a hadrosaur bill! It even has HOOVES!

Hooves are really easy to evolve. Why on earth shouldn't a cursorial flightless pterosaur have hooves? They should be on the hands, not the end of the wingfingers, but that falls under "People thought pterosaurs were bipedal in 1980."

The hadrosaur beak is rather dubious (although beaked pterosaur lineages have been known to atavistically regrow teeth, so it's not totally implausible.)

But apart from that, it strikes me as a perfectly legitimate use of convergent evolution. Probably shouldn't be the exact same colour as a giraffe, but why are you all going NOOOOO?

My speculative dinosaur project. With lots of fluff, parental care and mammalian-level intelligence, and the odd sophont.
