There is a pachycephalosaur (A.K.A. domehead, or bone-headed dinosaur) called
Colepiocephale, whose name literally translates to “knuckle head”.

Supposedly it was called this because of the vaguely triangular shape of its skull (resembling a knuckle joint), but I still can’t help but wonder if the person who named it was a fan of the Three Stooges.
