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 isRead More →

The Carboniferous clam species, Astartella concentrica Conrad 1842 has been found in rocks dated from 318.1 million to 298.9 million years ago [1]. This is a range of 20 million years. The genus, Astarella, is found in a much larger range, 326.4 to 247.2, or 79.2 million years of time.Read More →

Wilkingia

The genus Wilkingia was described by Wilson in 1959. The species W. terminale was described by Hoare in 1961. A very common bivalve, I have collected a few dozen specimens of Wilkingia over the past year. I have collected 10 different specimens that were complete as far as length goes.Read More →

Wilkingia

Described by Hall in 1852, specimens have been found from the Brush Creek Limestone and Ames Limestone of Ohio. I have found a large number of specimens here in Parks Township, and this is one of the best ones to date. Both sides of the specimen are detailed and itRead More →

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 →

The clam Palaeoneilo is easy to spot on this specimen of shale. But, what I assumed was Lepidophylloides under the Microscope really sold me on adding this to my formal collection. Is it a leaf or a spine? However, after some further discussion with more seasoned fossil experts, the LepidophylloidesRead More →
