Jaws agape, a 6-foot-longHyboduspursues a swarm of squid-like belemnites 180 million years ago. One of the most common sharks during the "Age of Dinosaurs",Hyboduslived in the sea alongside the ichthyosaurs and plesiosaurs, but it had smaller relatives (some as little as 6 inches long) that lived in streams and rivers.

To the lower left isPalaeospinaxwhich belonged to the lineage that gave rise to all modern sharks and rays. Typically less than 3 feet long, it was one of the first sharks to have solid vertebrae instead of a cartilaginous backbone found in more primitive species of sharks with which it lived.
