The prize that everyone seeks at Calvert Cliffs is a fossil megalodon tooth – the hand-sized weapon of a 60 foot shark that cruised this area in the Miocene (roughly 20 to 5.3 million years ago).  But other, more ordinary shark tooth fossils can be found (upper right), as well as mollusk shells (whelk, scallops – not shown), pieces of whale bone (middle left), dental plates from rays (middle right), and the teeth of an ancient super-sized crocodile (bottom).
