In writing the most recent research article, Aviculopinna, I set up an area to photograph specimens. While having this setup available, I went ahead and re-photographed the first seven specimens in the fossil catalog. Specimen CG-0001 John Harper identified this specimen as possibly being Orthotetes, a brachiopod. The preservation isRead More →

Eomarginifera longispinus brachial valve underside

Yet again, I need to reverse the identification of the specimens below. I will be altering the article, but the specimen referenced found in the Brush Creek limestone is not E. longispinus, but Kozlowskia splendens. L. longispinus is found in the late Mississippian of European and U.K. rocks. Eomarginifera longispinusRead More →

Kozlowskia splendens is a species of brachiopod described in the Brachiopods of Ohio book. The species is reported from the Brush Creek limestone. I originally wrote this post about specimen CG-0008, but it turned out to be Eomarginifera longispinus. The difference? The so-called ears of the shell. This is theRead More →

Rugose Coral Specimen

Lophophyllidium and Stereostylus are the two known genera of Rugose Corals in the Glenshaw Formation. Locally in the Brush Creek limestone, they are common to find. They are hard to recover from the hard limestone and don’t come out in one piece. The Pine Creek limestone locality, however, is quiteRead More →

Worthenia tabulata specimen CG-0110

The gastropod Worthenia tabulata is a more popular species than some that I have written about. A quick search online reveals more pages than average compared to others. This genus of gastropod existed for 216 million years in the fossil record, surviving the Permian-Triassic extinction that many local genera diedRead More →

Tolypammina sp

Tolypannina and encrusting forams in general are a new subject for me. I have long wondered what the tiny growths were in many specimens I have collected. I recently attempted to identify the Crinoid Calyx Plate specimen. @Missourian, a member of the Fossil Forum, noticed that it was likely coveredRead More →
