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.

I found this specimen along with some other fossils during a fossil hunt. This vertebra is very peculiar and unique, due to its small size, and it’s composition. It is completely permineralized by hematite, making it feel much heavier than the average rock. It almost feels like a chunk of metal. Probably belongs to one of the endemic hadrosaur species of the Cerro del Pueblo Formation, such as Velafrons coahuilensis, or Latirhinus uitstlani.

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

Hello, this spring break I found this vertebra in late Campanian sediments from southern Coahuila, Mexico. It comes from the Late Campanian, Cerró del Pueblo Formation, around 73-71 million years. This was found along with marine and terrestrial fossils. It is about 1 cm long (3/8) of an inch, 1 cm in width, and 1.1 cm in height. I want to know what type of dinosaur this vertebra belonged to and whether it’s a caudal vertebra or not. My thoughts on this specimen at the moment, is that it’s probably a caudal (tail) vertebra from a small theropod dinosaur, something like a dromeosaur or a troodo

A book on Mesozoic reptiles of Mexico will be out in 2014...... http://www.iupress.indiana.edu/product_info.php?cPath=1037_3130_3175&products_id=807153 While Mexico's biggest claim to fame in Mesozoic history is that it boasts the asteroid impact site at Chicxulub on the Yucatan Peninsula, what very few people know is that Mexico during the Mesozoic was once inhabited by marine reptiles and boasted the southernmost occurrences of North American ankylosaurs, ceratopsians, tyrannosaurs, hadrosaurs, and dromaeosaurs. While "Plesiosaurus"mexicanus and Amphekepubis were the first Mesozoic rep
