Catalog Number: CG-0008 Update: This has been identified as Eomarginifera longispinus. This specimen came out with more detail than I’ve ever seen in a Brachiopod locally. I was knocking off eroded edges from a large piece of limestone when this showed up. Surprisingly, I was able to wiggle the specimen
Update: This may be Euphemites. Examples from the Pennsylvanian Atlas of Life. Euphemites is a genus of the Bellerophontidae family. It is firmly within the Mollusca phylum, but exact taxonomy is not universally agreed upon. I will likely have a lot of unidentified pieces. This includes many brachiopods, as they
Punctospirifer was first described by North in 1920. In existed from 376 until 252.3 million years ago. It went extinct during the Permian Extinction. I believe my identification of this species is likely correct, but I’m not good with this type of Brachiopod. Upon seeing the large double grove and
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.
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
