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 →
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 →
A quick post as this specimen has much more work needed done before I can do a full write up. In the local stream there is a junction where two streams meet and turn into one. A piece of loose limestone, laying in the stream bed, was easily split. ItRead More →
Until yesterday, I was very singular in my knowledge of Pennsylvanian fossil shark teeth. Petalodus is the only genus of tooth I have found that I was aware of. I pulled an exciting piece from the rocks yesterday. This slab has a similar coloring to the Petalodus teeth I’ve seen.Read More →
The shark tooth, Petalodus ohioensis, is the most common vertebrate fossil found locally. I have collected twelve specimens from the Brush Creek Limestone and one from the Pine Creek Limestone. I have a comprehensive live research article in general on the entire genus, Petalodus, available on this website. Click toRead More →
This Solenochilus, an extinct genus of paleozoic cephalopod, was found today (Late August 2020) after splitting a piece of float limestone half-buried in the mud at creek level upstream in Guffy Run. The rock was three inches thick and had a long rectangular shape. A heavy blow to the centerRead More →
There are plenty of shale plants to be found, in particular layers locally. Some have an abundance of ferns, stems, leaves, etc, and often you’ll fine a nice isolated piece. This is a two part post about two particularly interesting finds. One is very easy to identify, the other IRead More →
