Seed/Nut? from the latest Campanian of Coahuila, Mexico

Recommended Posts

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.

I think nut or seed is a good guess.  We get similar things in the Lance Fm

 Do you think this could be embedded in a coprolite? I see fragments of other things embedded in the matrix.

That's a tougher call.
