I have found very little fossilized woody material in the Late Carboniferous strata locally. It most certainly exists, I just haven’t been lucky enough to recover any. That changed yesterday with the recovery of a fossilized taproot. The specimen was found in-situ in shale immediately above the Pine Creek limestone.
Plant fossils are very common in the Glenshaw Formation. The shale preserves a multitude of plant fossil specimens, waiting to be found. Preservation can be an impression or a carbon film. These carbon films are leftover carbon from when the original organism was alive. The oxygen, nitrogen, and hydrogen disappear
Without a doubt, the genus Metacoceras is one of the two most common cephalopod genera found locally. This particular specimen preserves inner chambers. It did split in half while I was recovering it, but to my surprise, everything remained intact. Individual septal wall/suture lines can be seen on close inspection.
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
Yet again, I need to reverse the identification of the specimens below. I will be altering the article, but the specimen referenced found in the Brush Creek limestone is not E. longispinus, but Kozlowskia splendens. L. longispinus is found in the late Mississippian of European and U.K. rocks. Eomarginifera longispinus
Kozlowskia splendens is a species of brachiopod described in the Brachiopods of Ohio book. The species is reported from the Brush Creek limestone. I originally wrote this post about specimen CG-0008, but it turned out to be Eomarginifera longispinus. The difference? The so-called ears of the shell. This is the
Lophophyllidium and Stereostylus are the two known genera of Rugose Corals in the Glenshaw Formation. Locally in the Brush Creek limestone, they are common to find. They are hard to recover from the hard limestone and don’t come out in one piece. The Pine Creek limestone locality, however, is quite
