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
Two examples of local fossil plant fauna, both specimens were found in Guffy Run. Calamites Calamites is common in the shale below the Brush Creek Limestone. Typically a wide, long and flat fossil, it’s difficult to find large specimens locally in-tact. This one was face up in the stream bed
Macroneuropteris is a much more rare genus than Pecopteris. However, these can be found locally in the shale below the primary limestone layer. The detail within the leaf of this specimen is stunning in my opinion. The Middle Pennsylvanian Sydney Mines Formation, found in Nova Scotia, Canada, have revealed a
Closely related to modern horsetails, Calamites is an extinct genus that existed from the Carboniferous until the early Permian. Horsetails are one of several genera considered to be living fossils. They reproduce using spores, which were similar to Lepidodendron. Both Lepidodendron and Calamites produced cone arrangements of spores. This genus
My daughter found this Lepidodendron specimen during a quick expedition to explore exposed shale along a steep roadside hill. It was lying alongside the road on a raised dirt pile on top of the soil. Logically, I believe this piece was unearthed while PennDot was making road repairs. This piece
