Paleoneilo

The genus Edmondia was first described by de Koninck in 1841. The book is Description des animaux fossiles qui se trouvent dans le terrain carbonifĂ©re 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.Read More →

Amphiscapha

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 restRead More →

Bornite

Bornite, also known as Peacock ore, is a mineral that tarnishes to different colors, ranging from blue, yellow and purple. This is the first sample of it I have found locally, right in my local shale pile. I have a feeling that I will be finding more of it nowRead More →

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 →

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 genusRead More →

Crinoid Columnal Lumen

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 theRead More →

Macroneuropteris

Macroneuropteris is a seed plant that has a temporal range only in the Carboniferous. I found this specimen in the talus near the lab. Most specimens I find are of small leaves, or large pieces of bark. This was more certainly a large leaf. I wanted to show the leafRead More →

Wilkingia

This specimen is probably Wilkingia. But it could also be Phestia. I compared photos from a quick web search of each and I found examples of Wilkingia to be far more comparable. Wilkingia lived from the Carboniferous until the Permian periods of time. This particular specimen is from eroded matrix,Read More →

Punctospirifer was first described by North in 1920. In existed from 376 until 252.3 million years ago. It went extinct during the Permian Extinction. I believe my identification of this species is likely correct, but I’m not good with this type of Brachiopod. Upon seeing the large double grove andRead More →
