Sharks first appeared about 370 million years ago. Sharks belong to a group of fish that have a skeleton made of cartilage instead of bone. Most of the time the only fossilized remains of ancient sharks we find are their teeth, but in a few cases we have come across shark vertebra and gills. Some ancient sharks grew as long as 64 feet.
