@InvaderXan okay but if it’s that old, how do we know what any fleshy features looked like?
@troodon @InvaderXan that’s what I mean, I’d assume inner ischia or pubis showing muscle attachments but wouldn’t that mostly show the crus penis? And you’d need a really unflattened pelvis or fleshy impressions so if we have those that’s a seriously awesome fossil!
@Leucrotta @InvaderXan traces of muscle connections on bones, and traces of soft tissues on the other surrounding rocks--like the imprints of feathers or skin, detailed enough to glean color information from the molecular structure. as far as the descended testicles... like the OP said, "thought to have been present," but until/unless we get fossil confirmation, it's really just a scientific guess. ;)
