Spines in Brachiopods rarely survive in the local rocks. While I believe I have found a few already separated, I rarely see one actually embedded on the shell. I found the 1mm long spine on this Brachiopod specimen I brought back this evening after freeing it from float limestone withinRead More →

Euphemites, maybe

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 theyRead More →

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 andRead More →

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.Read More →

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. ThisRead More →

Not sure what this is. I feel like it is common. What was interesting is the original shell material and the fact that is was two shells stacked. The first assumption I’ve heard is that is it Linoproductus.Read More →
