Every fossil hunter dreams of finding a megalodon tooth but until then they can sport one of our wire-wrapped fossil shark tooth necklaces. The tooth size varies from 3/4" to 1 1/4" and hangs on a beaded necklace. Please allow us to choose one for you. The Calvert Marine Museum does not sell fossils collected from Calvert Cliffs. Our goal is to preserve scientifically important fossils for the greater good.
