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.

This is an old Idea (tm) that I was holding on to for a while. Might as well release it.

I'm guessing we all know how Science Marches On, and how many, many pieces of older paleoart are completely out of date. I don't mean featherless ceratopsids, I mean quadrupedal megalosaurs, tail-standing tripods, sprawling sauropods, bat like pterosaurs, and tree-climbing hypsilophodonts.

In short, the aim of this project is life imitating art.

So what kind of scenario is this? Alternate? Future?

In the end, the best advice I could give you would be to do your project in a way that feels natural to you, rather than trying to imitate some geek with a laptop in Colorado.

I guess it's alternate, but I'm not sure. It's not meant to focus on how these creatures evolved, but, if they had been what dinosaurs were like, what their world would have been like, what species would have existed, how niches would have been filled...

The pterobats are very easily dismissed as flying marsupials, as the people who found their fossils discovered, or as volaticotheres; indeed, one of my contributions to Spec were volaticotheres akin to those things.

The rest are just weirdass sauropsids. I guess you can turn them all into squamates in a Squamozoic project, but that is uncreative and stupid, so:

- The retro iguanodonts that look like dragons and retro megalosaurs could be sister taxa; one became carnivorous, another became herbivorous. They could be monitor lizards, but something like derived sphenodonts is without doubt much better.

- The retro hypsilophodonts and retro iguanodonts that resemble reptilian kangaroos could be a linage that evolved from Effigia like ancestors, one taxa becoming ground sloth analogues and the other tree kangaroo analogues

- The swimming sauropods could be aquatic members of some basal herbivorous linage of sauropsids I forgot the name, while the retro sea reptiles could either be champsosaurs or thalattosaurs

I played around for a while with the notion of a n Ultragalapagos. Essentially, a Galapagos island complex about ten or fifteen times the size or the current version, remaining a dry marginal landscape, where Iguanas and Tortoises continue to diversify. These creatures could pass beautifully as the ultralizards of the ultragalapagos.

Love making retrosaurs. Today I explained to my dad how dinosaurs did not use their tails to stand and how say, velociraptor, is a genus not a species.
I do art sometimes.

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.

Maybe the retrosaurs are all derived iguanas, monitor lizards or sphenos.... Weird flying mammals for the retro-pterosaurs.
