This week’s Fossil Friday features the skull of an animal that is a little scary to me—let’s just say I wouldn’t want to come face to face with this fellow. According to my sources, this species was one of the lucky few to survive the K-T extinction.
Though you may hear the ticking of a clock as you try to answer this question, never fear: you have until Monday to comment below. It’s only in a theater that the sound of a ticking clock would warn of a representative of this species, however, not in the real world...
So who was this dangerous looking fellow?
