Megalodons are among the most sought after teeth in the Calvert cliffs and other nearby Miocene exposures.

most of the meg teeth are in the 1 - 3" class in these Miocene exposures.

megalodons can sometimes have cusps on their teeth. Therefore, some subauriculatus identified below could be juvenile megalodons.

The fossil bearing Calvert Cliffs of Maryland is part of a large collection of fossiliferous exposures, called the Chesapeake Group. The Chesapeake Group encompasses exposures around the Chesapeake bay, D.C., Maryland, and Virginia. These exposures were created by sediment accumulation in the Salisbury Embayment, an area encompassing the Delaware, Maryland, and Virginia coastal plains which is often covered by the ocean (Kent, 1994, p.111).

The Calvert Cliffs run for roughly 24 miles from near Chesapeake Beach to Drum Point on the western shore of the Chesapeake Bay in Maryland in Calvert County. These cliffs contain an amazing Miocene fauna. More than 600 species of fossil plants and animals have been found here (Glaser, 1979, p.56). Among these countless species, are a wide variety of marine animals such as porpoises, whales, seals, sea turtles, sea cows, and crocodiles. Also, parts of land mammals are occasionally found, the most common being the peccary; a pig like animal. However, more interesting creatures have been found, such as mastodons, wooly rhinos, and camels. Also, the cliffs boast an extremely diverse sea life, from countless genera of sharks and rays (including C. megalodon), to many kinds of fish. Most of these fossils are found as bone fragments, and isolated teeth.

Around this time in the early to middle Miocene, the Salisbury Embayment was a shallow sea. It is thought to have been used as a calving ground for many species of early dolphins and whales. Since there were so many marine mammals here, the largest of prehistoric sharks, the Megatooth sharks (including C. megalodon), spent a lot of time feeding here. The climate was warmer than it is now, so on the shore, a diversity of plants grew here, from Cyprus trees to Oak trees.
