Central Pennsylvania (USA); Pottsville Formation, grey shale.... in situ boulder removed and split at home For starters, it does split but it also kinda breaks into hunks and crumbles a bit. Is that correctly described as "nodular shale"? There are a lot of slender black long things without a great deal of definition, and one piece has these round shapes. I think I'm looking at Stigmaria rootlets and where the rootlets attach to the main root. I'll try to add photos of presumed rootlets later. Would welcome any further enlightment. Thanks!

I am a quarry geologist in PA and rarely need to identify fossils. However, I found this cool one that I just can't ID from publications if google searches. It was found in a quarry near Pottsville and St. Clair, PA. It is from the base of the Llewellyn Formation. I found some photos of fossils that look similar but usually each "scale" (not sure of the proper term) is more like an inch, but as you can see by the penny in the picture these are much smaller. Help!
