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 re-investigation;Read More →

The genus Odontopteris is one of many seed fern varieties that existed during the Carboniferous. I have high confidence that I have the genus correct, yet, I am awaiting more research before I can confirm. The visible leaf of the glued specimen is 100mm in length.Read More →

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 →

The fossil Amphiscapha appears readily within shale locally. Buried at an angle different from the plane the shale sheared from, this specimen is a bit unique. Only the raised rim was visible initially. Using precision tweezers, I slowly used the sharp metal ends and a microscope to reveal the restRead 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 →

A fourth Petalodus Tooth has been found in the same general area I found the first three teeth. This tooth looks deep, like the 2nd tooth. The two sides are missing and fractured, likely from splitting the rock. The tooth was dark in color when I found it and turnedRead More →

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 →

Update! This specimen turned out to be a Schistoceras, my first found Ammonoid. Ammonoids are a type of Cephalopod with intricate septal chambers, having intricate patterns throughout. The outside of the creature was covered with the lines seen below. They also have the same basic shell shape as the BellerophonRead More →
