Propatagium (video)
Here you can see the extensive propatagium that it inherited from its pterosaur ancestor.
How could a non-pterosaur descendant develop a propatagium?
ReplyDeleteNot sure I know what you mean.
ReplyDeleteWhat I mean is other creatures have propatagiums who aren't descendants of pterosaurs. How could they get them if they didn't descend from pterosaurs?
DeleteAny dinosaurs have a propatagium?
ReplyDeleteNo but why would that matter? Are dinosaurs purported ancestors of pterosaurs?
ReplyDeleteI will stop wasting time on you.
