The Hell Creek Formation in Makoshika State Park is located in Glendive, MT. The formation, deposited during the Cretaceous, is composed mostly of sandstone, mudstones, and freshwater clays. The formation includes a plethora of dinosaurs and marine reptiles. It's a scientist's dream formation--including areas of study for archaeologist, paleontologists, & geologists.
This exposed hillside is part of the Hell Creek Formation. Our class was given permission to go on city land to look for fossils. In this formation we found a stygimoloch which will be cleaned up at MSU and then returned to be displayed by the city.
Graduate student Dan, who taught the course, studies turtles. Whenever we found turtle fossils he'd get really excited. I love seeing people passionate about their work!
Around the concretion where we found a Stygimoloch we were looking for all the float bone. This video shows the process.
