This specimen of Solenochilus was an interesting find in softened Brush Creek limestone material. The limestone can often be bisected as discovered in the ground. This is likely from stress fracturing. In between the fractures, I have mostly found clay. But the margins on each boulder can be softened and
If I find a large convolute cephalopod in local Brush Creek Limestone, it’s usually the genus Metacoceras. Each find is a unique opportunity to study the genus as a whole. It’s the luck of the draw that determines how each will present itself, once a rock hammer breaks open a
This tiny late Paleozoic gastropod is most likely identified as Strobeus brevis. Measuring somewhere between four and five millimeters, this snail would be difficult to spot if you were not looking for it. This makes identifying it slightly more difficult, with small morphology to compare. Its spire does have a
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
This starts a series of posts on Fossils NOT of Parks Township. I traded some brachiopods to a collector in France for an exchange of Ammonoids from France. The first specimen I focused on is a Jurassic species with a temporal range of 180.1 to 175.6 million-years-ago. I know little
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.
I still have only found two examples of the genus Neospirifer locally. I spent three or more hours on this one, carefully removing excess parts of the limestone matrix. I’ve been getting more patient with the air scribe, turning it down to work on more delicate areas. There are well
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
