Calvert Cliffs
Miocene Period 23 - 8 Million Years Old
Maryland's Calvert Cliffs extend approximately 24 miles along the western shoreline of the Chesapeake Bay, from Chesapeake Beach and south to Drum Point. Famous for their Miocene fossils, they feature over 600 identified species of plants and animals, such as sharks, rays, porpoises, whales, and even land mammals like peccaries and mastodons. With most fossils being various shell types, bone fragments or teeth, each trip to the cliffs offers a chance for an amazing discovery! Nearly all of our chartered visits to the cliffs will yield shark teeth, ray plate fragments, shells and other fossil treasures to take home!

Megalodon
The Megalodon shark (Otodus Megalodon/Carcharocles Megalodon). Otodus Megalodon in Greek means - Otodus "Ear-Shaped Tooth" and Megalodon "Big Tooth". Megalodon teeth can be as large as 7"+ in length, with more common finds being in the 2"–5" range. Although still rare (not every hunt will yield a "MEG"), they are considered the holy grail for many shark tooth hunting enthusiasts and can still be found along the Calvert Cliffs today. Meg's have been extinct for approximately 3.5 million years.
