Sharks don’t have bones, but they still can fossilize. As most sharks age, they deposit calcium salts in their skeletal cartilage to strengthen it. The dried jaws of a shark appear and feel heavy and solid; much like bone. Shark skin feels exactly like sandpaper because it is made up of tiny teeth-like structures. They can go into a trance when they are flipped upside down. Aging a shark is similar to aging a tree - scientists age sharks by counting the rings on their vertebrae. A whale shark’s spot pattern is like a unique fingerprint.
