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. 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 →

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 →

Crinoid Calyx plate with scale

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 →

This 15th specimen of Petalodus ohioensis was lying right out in the open today. The odd part was its placement. Last Fall I had pulled a piece of limestone to shore and was attempting to split it. I cleaved off a few small pieces. However, it was getting late andRead More →

Update: This specimen was not a Bellerophon. It was a Pennoceras. The genus Bellerophon is chock full of different species. This particular specimen was found in the soft punky later over top of the limestone, right after I found a specimen of Pulchratia. I often find pieces of these, butRead More →

Pulchratia is a genus of brachiopod known from the Late Carboniferous through the end of the Permian. After doing some visual research with local fossil plates, I settled on the genus Pulchratia. I considered Juresania, which is a sister genus within the Echinoconchidae family, but Pulchratia fit better. This isRead More →

The Carboniferous clam species, Astartella concentrica Conrad 1842, has been found in rocks dated from 318.1 million to 298.9 million years ago [1]. This is a range of 20 million years. The genus, Astarella, is found in a much more extensive range, 326.4 to 247.2, or 79.2 million years. TwoRead More →
