Well, I have read that they found some dicynodont skin impressions and they
looked "reptillian" which means that they probably were Mammal-like reptiles,
while cynodonts probably looked like mammals.
of whether these animals may have looked like mammals
was raised on the list almost two years ago ...
keyword "Morganucodon" will be a tremendous help,
since the threads focused on it. >>
thanks, I'll look it up.
