Without a doubt, the genus Metacoceras is one of the two most common cephalopod genera found locally. This particular specimen preserves inner chambers. It did split in half while I was recovering it, but to my surprise, everything remained intact. Individual septal wall/suture lines can be seen on close inspection.Read More →
I still have only found two examples of the genus Neospirifer locally. I spent three or more hours on this one, carefully removing excess parts of the limestone matrix. I’ve been getting more patient with the air scribe, turning it down to work on more delicate areas. There are wellRead More →
In continuing new specimen photography, I have completed the photography for all Wilkingia terminale in the catalog. I have described some specimens in the text below. CG-0012, Wilkingia terminale The specimen is nearly 7 cm in length, from posterior to anterior, and 2 cm between margins. Growth lines are visibleRead More →
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 →
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 →
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. Unfortunately, they are hard to recover from the hard limestone and don’t come out in one piece. The Pine Creek limestone locality, however, isRead More →
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 →
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 →
Crinoid Calyx specimens are well known in the world of paleontology. I personally have not found one that I could identify as such. Crinoid columns are very common in local rocks. However, Crinoid Calyx pieces seem to be rare locally. I found several columns just yesterday, when collecting limestone thatRead More →
