Genyodectes711 Posted September 23, 2022 Share Posted September 23, 2022 Found this really weird fossil the other day while hunting for brachiopods. It comes from Permian limestone marine/coastal deposits in Dona Ana County, NM near Hatch. The area is a brecciated limestone field. I've collected coral, brachiopods, crinoids, gastropods, and echinoderm fossils from here before, but they aren't always the best preserved. This rock contains fusulinids, she'll fragments, crinoid bits, and echinoderm spines but I have no idea what the large... interesting looking.... fossil is. It appears to have some enamel left on bits of it, so I think it is a shelled organism of some variety. Any help appreciated! Link to comment Share on other sites More sharing options...
DPS Ammonite Posted September 23, 2022 Share Posted September 23, 2022 (edited) Welcome to the Forum. It might be Wilkingia terminale, a common Pennsylvanian and Permian bivalve. Find the name of the Permian formation and see if that species is present. https://fossil.15656.com/2020/04/20/wilkingia-terminale-collection/ Edited September 23, 2022 by DPS Ammonite 2 My goal is to leave no stone or fossil unturned.
