Hello, we found this bone fragment last month. It comes from Coahuila, Mexico, from the Cerro del Pueblo Formation, which is late Campanian in age (~72 million years old). All sort of dinosaur fossils are found at the formation, including ceratopsians, hadrosaurs, and tyrannosaurs. To me it looks like an ungual (toe bone). But the end of the piece is more blunt and rounded than most other ornithischian unguals I’ve seen online. Can any of y’all ID this piece, or is it just a regular unidentifiable chunk of bone?

Last Spring Break I took a fossil hunting trip to the Late Cretaceous Cerro del Pueblo formation of Coahuila, Mexico. Found a lot of cool stuff, including partial tyrannosaurid teeth, a partial hadrosaur tooth, a bunch of turtle carapace pieces, a croc vert, a lot of Ankylosaurian osteoderms, tons of freshwater and marine gastropods, and much more. This piece stands out, because I have been unable to ID it. My best guess would be a Pedal Ungual from some dinosaur, but it is unlike I’ve seen online. I’m hoping some dinosaur experts can help me out.

Hello, I found this fossil last spring break, in Coahuila, Mexico. It comes from the late Campanian (73-71 Myrs) Cerro del Pueblo formation. I found several fossils at the same location where I found this fossil. Some of the fossils I found include Cerithium snails, several species of Physidae freshwater snails, Inoceramus sp., petrified wood with teredolites, ammonite fragments, a caudal vertebra from a Hadrosaurid, and plenty of dinosaur bone fragments. The formation is a mess, it’s composed of layers that were deposited in marine, and terrestrial environments, as well as rivers and possibly swamps. Even though I’m very knowledgeable of the formation, and the fossils that have been found there I still have no idea as to what this specimen is. My best guess at the moment is that it’s some type of plant material maybe a fruit or a seed. There have been numerous plant fossils found at the formation, including fruits. I also think this could be embedded in a coprolite, with the rounded object being embedded in it. Let me know what you guys think about it.
