In finding marine fossils locally in the Glenshaw Formation, I have noticed three distinct preservation types within limestone. This does not indicate that there are only three, but these are the most common I have identified. All of these involve the preservation of marine creature’s remains in limestone. Limestone is
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
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
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
