Hello! I found these foot bones (called tarsals I believe?) from Wibaux county Mt in the Hell Creek formation. The seller says that there’s a possibility these are theropod bones, specifically saying bone 1 might be a dromeosaur bone, and bone 2 could possibly be from a tyrannosaur. I looked at some photos online and the only real difference I could tell is some of the dromeosaur bones could be proportionally longer. I also don’t know how to tell if these are even from dinosaurs or some other reptile/bird. Any help would be appreciated! Thanks.
