Going by the fossil example shown on the Pennsylvanian Atlas of Ancient Life, I am calling this find a Pseudorthoceras. The rock was split into two pieces, and the photo is of them joined back up. The white markings are from an air scribe. Pseudorthoceras belongs to the class Cephalopoda.
This brachiopod is beautifully centered in what is likely a concretion circle. The specimen was found in the high-hill shale. This layer contains a shale that I call mud stone. It comes out in larger pieces than thinner shale. The rock still splits rather easily, and it contains many concretions.
Listed below are specimens that I don’t have a solid identification for. I will continue to update this page as I add new pieces. As I am not an expert in fossil identification by any means, I prefer to get identification as opposed to just guessing. Pieces that need final
Antiquatonia portlockiana was first described by Norwood and Pratten in 1855. The genus Antiquatonia includes eight distinct species. It has a surprisingly short age range of about 20 million years. The species has yet to be found outside of the Carboniferous Period. When I first found this brachiopod, I wasn’t
After finding a great Sea Pen example, I also found this one that had set aside. The specimen passes through the rock, therefore showing itself on the other side as well. A Crinoid stem impression can be seen on the opposite side. The first one I found was Pteronites.
Composita was a genus of brachiopod from the Late Devonian up until the Late Permian. There are a few pieces of the original shell attached to the fossilized inside. This form of fossil is also known as a Steinkern. This species is very common in the local marine zones. This
By far the largest Crinoid Stem I’ve found so far. This was in a thin triangle of Limestone and was easy to get out. I count six columns stuck together here. Crinoids are very common locally, however larger ones are more rare. I still would like to find a Crown
A sea pen from the genus Pteronites. I am still looking for more information about Pteronites in general. There is also a second example available. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: Pennatulacea More about Pteronites Fossilworks – listing on Pteronites
Pseudorthoceras was first described by G. H. Girty in 1912. It was part of a paper describing new species of Pennsylvanian fossils from the Wewoka Formation of Oklahoma. The species appeared 376 million years ago and disappeared during the Permian–Triassic extinction event, 252 million years ago. This extinction, known as
