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 →

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 →

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, however nothing with detailed ornamentation like this example. Next I will haveRead More →

I was not quite sure about the genus of this small Brachiopod that was found today. It came from the soft punky layer on the top of the limestone. This layer is soft and typically wet. Through water interaction, it has made the typically hard limestone into a soft matrixRead 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 larger range, 326.4 to 247.2, or 79.2 million years of time.Read More →

Top view of Neospirifer

I have seen a few specimens of Neospirifer locally, however none this large and in as good as shape. I have settled on this being the genus Neospirifer (Fredricks 1919), or at least something from the Spiriferidae family. The prominent groove down the middle of the shell with two raisedRead More →
