In writing the most recent research article, Aviculopinna, I set up an area to photograph specimens. While having this setup available, I went ahead and re-photographed the first seven specimens in the fossil catalog. Specimen CG-0001 John Harper identified this specimen as possibly being Orthotetes, a brachiopod. The preservation is
The genus Edmondia was first described by de Koninck in 1841. The book is Description des animaux fossiles qui se trouvent dans le terrain carbonifére de Belgique, written in the French language. The genus occurs from 252.3 to 457.5 million years ago. It died out during the Permian–Triassic extinction event.
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 utilized the sharp metal ends and a microscope to slowly reveal the rest
Amphiscapha is a commonly recovered genus of gastropod fossil in Parks Township. It appears often as a flat spiral within the 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
Closely related to modern horsetails, Calamites is an extinct genus that existed from the Carboniferous until the early Permian. Horsetails are one of several genera considered to be living fossils. They reproduce using spores, which were similar to Lepidodendron. Both Lepidodendron and Calamites produced cone arrangements of spores. This genus
Crinoid columnal fossils are very common in my digging locale. After finding a mollusc in the shale/limestone boundary above the limestone layer within the mid level shale pit, I noticed a tiny deep slot in the rock matrix. For whatever reason, the original crinoid had eroded away and only the
