Crosswise cells or rays are typical but often hidden components of the vascular tissue in plans. Fossil plants occur in the shale layers below the Brush Creek limestone. These sometimes preserve incredible detail, including detailed carbon films from plants living over 300 million years ago. While shale plant fossils are
Cordaites and Calamites are two familiar plants in the Late Pennsylvanian fossil fauna. The two are similar as fossils, presenting as long horizontal grooves in rocks. Cordaites differs from Calamites as the latter has a termination of the groves with occasional perpendicular grooves coming from the presence of nodes. I
Recently I was able to obtain two nice examples of Lepidodendron from the Pottsville Formation in Alabama. This formation is two formations away from the Glenshaw, having the Allegheny Formation between them. Both specimens are different species, however, species for these could very well just mean they come from 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
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
