What does Tetrapodomorpha mean?

The fact that the bot equals pterosaur to "lizard with wings and a Tyrannosaurus-esque head because it´s prehistoric" is nothing short of hilarious imo. Wish actual paleoart were used more often, despite the comission costs.

Thanks for the guide, it's hard to think of dromaeosaur arms without the JP pronated wrists coming to mind. Is there any place where I could find leg drawing guides? The lower foot anatomy is tough to picture.
