Yes, the Cotylorynchus romeri dinosaur, a synapsid (the ancestor of mammals) that lived in the Early Permian period about 300 million years ago, did look kind of like a pinhead. Plus, it's kind of chonky.
But don't laugh at all that girth - that's actually how the herbivore stayed alive: it was simply much, much larger than any predator of the era.
