Hello, I'm interested to know if there's any way to narrow down what kind of animal this fossil is from? My dad tells me it was given to him by my great grandmother, who likely purchased it from a university in Western South Dakota in the 1940s or 50s. Our assumption is that it would have been discovered in that area, around that time. The fossil is about 4" x 1.5". I think it's so cool, but beyond guessing that it's "a bone" from "an animal that had bones," I'm at a loss. Thanks for any help!

Found this on the side slope of an old road cut near the Cheyenne River in western South Dakota this morning...my first thought was turtle but after looking at fossilized turtle pics on line I don't think so. Could it be a dinosaur egg? It is about 18" long by 12" wide. When I grasped it and pulled on it it started separating into chunks as you can see in the second photo, and what looks like it could be the outer shell started separating from the outer portion (some pieces can be seen in the dirt to the right of the fossil(?) in question. Any help with ID would be greatly appreciated. Thanks!
