Professor Cheryl Wilga holds a 3-D model of an actual fossilized shark's tooth. This is a single tooth; the many sharp edges are cusps of the same tooth. A new book by Susan Ewing documents how scientists, including Wilga, helped figure out that this single tooth was embedded in the shark's lower lip and used to tear soft flesh.
