Ostracod fossils are of the class Ostracoda, belonging to the subphylum Crustacea. As far as I understand it, they are typically a microfossil in my area. Ostracods have been found as far back as 450 million years ago and are still an extant class today. They are also known asRead More →

Amphiscapha is a common fossil in Parks Township. It appears often as a flat spiral within shale. This particular specimen was accompanied by two Meekospira. I used a pair of engineering tweezers to remove some matrix from the sides of the larger of the two Meekospira. First described in 1942Read More →

This tiny gastropod is likely from the genus Glabrocingulum. First described by Thomas in 1940, Glabrocingulum has a geologic range of 353 to 205 million years ago. Being so small, it was difficult to identify via fossil plates alone. It has the raised edge with a bump pattern, but itRead 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 →

This small gastropod was found embedded within limestone in what I now call my limestone pile. As I collect limestone from the surrounding hillsides, The pieces I can carry end up here. There are over 62,000 species of gastropods, and they first appear during the early Cambrian period of time.Read More →

Spines in Brachiopods rarely survive in the local rocks. While I believe I have found a few already separated, I rarely see one actually embedded on the shell. I found the 1mm long spine on this Brachiopod specimen I brought back this evening after freeing it from float limestone withinRead 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 →

Ever since I’ve figured out what they were, local Pinna fossil specimens are a personal favorite to find. In examining the remaining shell material in these fossils, I have been able to see the prismatic layer represented on the shell hinge in at least two specimens. The specimens below showRead More →
