Carboniferous Pennsylvanian seed fern specimens (pteridosperms)
ntloux posted a topic in Member Collections
I am attaching images of Pennsylvanian seed ferns that were identified by the collectors. The fossils from Kentucky were generally found in the shale around closed down coal mines on family farms. Hopefully these images may assist others in identifying their specimens. Comments/suggestions/corrections are welcome and I also would appreciate specimen identification beyond the genus level for many of the specimens. The first image is of a Pennsylvanian alethopteris specimen from eastern Kentucky: Pennsylvanian alethopteris from eastern Kentucky. Pennsylvanian cyclopteris (upper right) and macroneuropteris specimens from eastern Kentucky. Pennsylvanian eusphenopteris specimen from eastern Kentucky. Pennsylvanian mariopteris specimen from eastern Kentucky. Pennsylvanian Pecopteris plumosa specimen from Upper Silesia in Poland. Pennsylvanian pecopteris specimen from eastern Kentucky. Pennsylvanian sphenopteris specimen from eastern Kentucky. Pennsylvanian crenulopteris specimen from Mazon Creek, Illinois. A helpful Forum member suggested this could be crenulopteris acadica. This last Pennsylvanian specimen is from Mazon Creek, Illinois identified by one individual as Lobatopteris lamuriana and in addition a helpful Forum member suggested that it is possibly a diplazites unita.

Hello! I received these two pieces as a nice gift! I WANT to say Mariopteris - I think definitely in photo #1 - but photo #2, while I WANT to say Mariopteris, I am leaning a bit toward Eusphenopteris!

Can anyone say what the carboniferous plant in the lower left corner is? The vein preservation is poor, but is this maybe Mariopteris? Found at Cory's Lane, Rhode Island
