Re: Triassic mammal-like reptiles?

[Roberto Takata <rmtakata@gmail.com>]

So how about: synapsides?

(I don't know if "mammal-like reptile" is so misleading - they are, in
some senses, mammal-like. In some sense, they are reptile. Or we could
say: amniotes pertaing to the lineage that gave rise to mammals.)
