Fossil Turtle Shell? by: Doug It does look like a turtle shell. Did you find it near Colorado Springs? Get a stratigraphy map of the area in which you found this fossil. If you can pinpoint the place you found the fossil the map will tell you the age of the rocks found on the surface. With that info you can find out if that area was covered with water or dry land. You can also find out if turtles had evolved yet and what other animals were common at that time. This can help you narrow down the search. Turtles have been around for a long time. The first proto-turtles are believed to have existed in the late Triassic Period of the Mesozoic era, about 220 million years ago.
