#mammaloids

[a-dinosaur-a-day]

I personally call Dimetrodon and early synapsids like that "mammaloids" to differentiate them from the diapsid lineage (which I call reptiles for the sake of convenience). This linguistically makes sense to me because if humans are humanoid, then mammals are mammaloid.

Ooh I like that. I usually go with stem-mammals in most situations, but mammaloid is a great word
