well, technically...

there's no such thing as a reptile anymore, modern phylogenetics got rid of the word.
and no,
anything that sweats isn't a reptile.
so by the time sweat glands appeared the animals having them were essentially already mammals.

sweat glands are like nipples though- they don't fucking fossilize.

Mary Higby Schweitzer is the current expert on the subject, having spent the last decade looking for biomolecules in dinosaur bones. She's found hem, collagen, various other proteins.

she hasn't found a single fragment of DNA, and she doesn't expect to. Her expert opinion is that it is impossible.

I've never heard of anyone that seriously disagrees with her on that.

I was telling the other anon to fuck off.
the zoology hate on /sci/ is funny, I'm thinking of poasting dinosaur threads here daily to watch the autists have seizures.
