turtlefoot posted a topic in Fossil IDHey All, I don't know if there is even enough of a fossil here to identify. I am nowhere near good enough to give a real good guess. First thought was either a small piece of a cephlapod or chiton. If it is a gastropod, it is a type that I have never found before. It was found on the side of a dry creek bed near Willow Springs, Missouri, USA in an Ordovician Formation. The remnant that remains measures 13mm wide by 15mm long. The bed the fossil remnant is laying is measures 24mm long. There is an indented type of division going horizontally across the fossil. It does not go all the way through to make the remnant two separates segments though (just an indentation type of division line). Other fossils in the same rock include gastropods, a brachiopod and what looks like a very worn rugose coral. If anyone can give me a probably identification, I would appreciate it.
I have found this coiled cephlapod in Pennsylvanian age limestone in Missouri. I believe it to either be a temnocheilus or cooperoceras. I was wondering if there is anyway to tell if this fossil was silica. And if it was could it be prepped by using acetic acid. TIA!
