Re: 190 million year old mammal footprints found

Yeah, I realized that, but it was kind of obvious, so I decided not to say it. I believe it was alot more primitive as well. I think that the critter from 190 million years ago was a full fledged mammal.

Well, it pays to have a full timeline of mammalian evolution.

Wikipedia says that the critter from the end of the Permian was probably already warm blooded and covered with fur.

<<Diictodon, a dicynodon. Not a reptile in the cladistic sense.>>

Apologies if anybody beat me to it, but that critter's 60 million years plus older; Upper Permian.
