minnbuckeye posted a topic in Fossil IDI had the opportunity to collect plant fossils in Western Pennsylvania a few weeks ago. Success was had IDing the fern leaves. But I am having difficulty identifying the woody pieces found that are not Calamites. These came from the Glenshaw Formation, Mahoning Shale which is Pennsylvanian. I realize that a decaying swamp is full of twigs that likely are unidentifiable, but there seems to be structure in at least some of these which could lead to some sort of identification. I am hoping those knowledgeable with the Pennsylvanian flora can chime in. 1. Here are some larger pieces
Last month I made my last trip for the year into Pennsylvania. I was hoping to stop at Swope Quarry in Mapleton, but the site is now posted. With a quick change of plans, I decided to travel even further west and visit some Late Pennsylvanian marine sites that I had planning on visiting on a different trip. The two sites I visited expose the Brush Creek Marine Zone, Glenshaw Formation, Conemaugh Group. They date to the Late Pennsylvanian (Missourian). Fossil collecting at these sites was a lot of fun as the fossils just pop right out of the surrounding shale and can be picked up by hand. But t
I found this rock alone under a tree, so I'm pretty skeptical of it, but I'm also pretty curious. I looked up trace fossils that might look like this, and I thought it was pretty similar to Rusophycus. The rocks around it are from the Glenshaw and Cassleman Formations of late carboniferous Pittsburgh. The "print" is about 10 cm long in its entirety, and maybe a quarter cm deep or so. Could this be a print of sorts or is it just some funky weathering? Thanks!
cameronsfossilcollection posted a topic in Fossil IDFound this in some Pennsylvanian aged shale in Ambridge, PA at the well known mahoning exposure. It doesn’t have visible pinnae like the ferns I’ve found in the area, but it could just be a strange preservation. Any ideas - is this just a fern? Thanks!
