Sure but also there are some fossils that DO have skin, and some even have preserved organs. And some have feathers, which is a pretty good indicator that there wasn’t some large feature we’re missing.

No doubt we are wrong on lots of counts, but I think we have good evidence for a lot of it as well.

Do beavers enjoy..... Uppies??

What a marvellous time for paleobootyology.

Now I want to see some pics of dinosaurs with beaver tails

now think about apple fossils

We do now know that dinosaurs were the forbearers of birds. Those that told us they were reptiles still continue to push that however. They were warm blooded and it is now thought they had some sort of pre feathers.

I believe the same thing applies to archeology, The Experts claim to have an answer to every question and impute things on the ancient cultures that they have no way of knowing.
