There are two corals that occur locally. Stereostylus is a common solitary horn coral in Pennsylvania. These two specimens show perhaps the same species. The top piece on polished limestone is a cut cross section. The bottom piece is an eroded end sticking out of stone. The shell material erodedRead More →

Aviculopinna peracuta

I’m not certain on the genus and species. I’ve considered Meekopinna Americana and Aviculopinna peracuta as possibilities. However, upon reading an article from the Journal of Paleontology, the entire family is in need of some clarification. We understand, however, that the Paleozoic Pinnidae are in need of a complete reinvestigation;Read More →

Petalodus Tooth on limestone microscopic view

When I found my 4th Petalodus Tooth, I thought it was the 3rd. However it turns out that I did indeed find another one that I did not document. This one appears to be half a tooth. It sits on a large piece of limestone, that I may eventually cutRead More →

It is a fossil something, but I am not sure what it is. I’ve stumped the few people I have shown so far. It has the familiar look of Calamites, but does not have the nodes. It was also embedded within limestone, which I do not find any plant fossilsRead More →

Pyrite on fossil

This is a simple photo view of some pyrite on a local carboniferous limestone fossil. There is only a little bit of it exposed in this specimen, but it’s flat and you can see the metallic glow quite easily at first glance. I’m not sure what sort of shelled creatureRead More →

While appearing to be a cephalopod, Bellerophon is a snail. It has existed since the Silurian and disappeared shortly after the great Permian Extinction. I’m not positive this is Bellerophon, but the growth lines visible resemble the genus. More about Bellerophon Online Article on WikipedaRead More →

Pseudorthoceras side view embedded in limestone

First described by G. H. Girty in 1912 as found in Oklahoma. This specimen was 3/4 exposed as attached to a rock. I am not positive, but I believe it would break into more than one piece if I attempted to remove it. I am always finding either Pseudorthoceras orRead More →

Impressions are also fossils, such as the shape of a prehistoric fern leaf embedded in shale rock or the impression of a shell in limestone. Somewhat common in Western Pennsylvanian fossilsRead More →
