Turtles

Turtles have changed little since they first evolved more than 200 million years ago. Turtle shell pieces are another common fossil at Dinosaur Park, probably due to their durability. At least 3 prehistoric turtles are known from Cretaceous Maryland: 1 large land tortoise and 2 smaller pond turtles. The turtle Arundelemys dardeni is known from a nearly complete skull.
