UPDATE: This is not Strobeus, but Leptoptygma. Cleaning out the aperture makes this clear. April 2023. This tiny late Paleozoic gastropod is most likely identified as Strobeus brevis. Measuring somewhere between four and five millimeters, this snail would be challenging to spot if you were not looking for it. This
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.
