The Gryphaea Fossil is from the Cretaceous period, the ground is mostly covered with small shell fossils - about 90% of the ground is covered with them. The Gryphaea is also known as the 'Devils Toenail' because of its curved structure. It's outer shell part is layered in lines, cracks, and smaller minerals that are cemented into the fossil. All the Gryphaea is in the ground on the surface of the main location along the HAB ridge. The Longitude for the area is W 110 degrees to 47' 43''.8 and the Latitude for the area is N 38'24'16''.71 It shows that at one time there was life Billions of years ago under the Ocean in shallow areas, and these Gryphaea were alive at one time. Although some people only notice the Gryphaea there may be other fossils in the HAB ridge deeper maybe a few miles deep. Or maybe there are some farther away.
