@mackenzie-white whoa! I just googled the Chinle formation, it looks stunning. Hah, when I read that you all were collecting on the outskirts of a landfill, I was immediately reminded of a field course I took with my class at Montana State University. We were in eastern Montana, close to the town of Glendive, and also found some great fossils from the late Cretaceous (one classmate found part of a Triceratops horn) on the landfill outskirts!
@egardner we need to talk with the Southwest Paleontological Society so we can do a mini conference or go to the section meeting for GSA out there! New ages of fossils, amazing looking landscape.
