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 →

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

I went back to where I found the first Petalodus tooth, and the first rock I split open held another Pennsylvanian Petalodus tooth. This specimen is longer than the first one. It measures 1.5mm more narrow, however this is due to a chipped left corner. The limestone is a bitRead More →

Finding a possible Petalodus tooth is one of the gateway fossils that lead to my love of fossil hunting. My first find was a bust, but finally I have found the real thing. This piece came from the huge shelf rocks that outcropped inches from the creek bed locally. WeRead More →

Shansiella, a Gastropod

Shansiella was first described by Yin in 1932. It can be identified as such by viewing it’s bands and a distinctive selenizone on the aperture opening. There are large numbers of Gastropod samples to be found in Limestone and shale, but I rarely do I find ones that are asRead More →

Wilkingia

Catalog Number: CG-0012 My first Wilkingia find was in soft eroded matrix. I found this specimen while exploring a new locale. A 6 foot by 2 1/2 foot by 7 inch thick slab of limestone that was only 6 inches from the stream bed. With help, I slowly removed soilRead More →

Fenestella

While I have many sources of limestone locally, this specimen of Fenestella was one of my first finds in a new source. Just across the valley floor to the other side, a ridge of limestone cropped out just above the stream. While I’ve likely encountered many bryozoans in limestone, thisRead More →

Cephalopod found in Pennsylvanian Limestone

This specimen is a Sea Pen. Originally, I was classifying local Sea Pen fossils as Pteronites, however over the past 50 years, the naming has started to change. The type species Pteronites was originally named for species found in England (McCoy 1842). In 1978, a new branch named Meekopinna (YanceyRead More →
