Parallelodon carbonarius (Cox 1857) is a bivalve with distribution from the older Pottsville Group to the younger Conemaugh Group in Ohio and Pennsylvania. This is the first specimen of this species that I have found in over three years of searching through the Brush Creek limestone and the Pine Creek
In continuing new specimen photography, I have completed the photography for all Wilkingia terminale in the catalog. I have described some specimens in the text below. CG-0012, Wilkingia terminale The specimen is nearly 7 cm in length, from posterior to anterior, and 2 cm between margins. Growth lines are visible
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 Carboniferous clam species, Astartella concentrica Conrad 1842, has been found in rocks dated from 318.1 million to 298.9 million years ago . This is a range of 20 million years. The genus, Astarella, is found in a much more extensive range, 326.4 to 247.2, or 79.2 million years. Two
Wilsome described the genus Wilkingia in 1959. Hoare named the species W. terminale in 1961. A very common bivalve, I have collected a few dozen specimens of Wilkingia over the past year. I have collected ten different specimens that were complete as far as length goes. Unfortunately, many specimens are
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 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 Lepidophylloides
