I actually found this several years ago, around the time I started collecting, and always assumed it was a type of Calamites. However, I recently noticed that Cordaites leaves (such as this example) have a very similar appearance. I wouldn't have expected it to have been preserved so... cylindrically though? Roughly 1.5" wide. Thoughts?

Appears to be several clustered together. I was thinking that it could be the base of the plant, where several stems branched off a shared rhizome (as seen in figure a). Thoughts?

I was told in a group that it was an eroded garnet schist, and I did find a couple other examples online that looked similar. However, it looks more sedimentary than metamorphic to me. I also posted it on a mineral forum where they suggested that it could also be iron nodules in sandstone or a bark fossil. What's your take?

Having only found specimens with 1-2 nodes, I was pleasantly surprised to spot this poking out of the ground after a heavy rain yesterday. Just out of curiosity (and so I can properly label it in my gallery), could anyone tell me what species of Calamites it is (if possilble)?

I found my largest fossil yet yesterday. I assumed that it was Lepidodendron and was curious what species it may be, but it occurred to me after looking through images that I may have some other form of Lepidodendrales. Can anyone confirm? It's about 29cm (about 11.5") long with a circumference of 53.6cm (about 1' 9"). Leaf scars are about 3.5cm (about 1.4") tall by 1cm (about 0.4") wide. The scars wrap around the nearly-cylindrical specimen, only absent on roughly a third of the backside (last photo) where it may have broken off or is still hidden under the matrix. It was found in the Hyden Formation (Middle Pennsylvanian) in Johnson County KY. The closest result I've found has been Lepidodendron lanceolatum, but the pits are more centered than those in my specimen and I haven't been able to find any info on whether or not they occur in my area. Rockwood suggested that it may actually be Lepidophloios that has rolled-up at a 90 degree angle rather than being a Lepidodendron cast, which would be consistent with pit placement. What are your thoughts?

Decided to check out the trail next to my house after a heavy rain and found these. I think they're just siderite nodules (hence the orange coloring), but just making sure they aren't something... nicer. The first two attachments show a small hole in the center of the flatter end of each. The rest just show other angles (plus a large version of the pic above).

Fossil-finding is slowing down a bit after picking at the same area for 6 months, but here are a few more finds (that may or may not be fossils) that I'm curious about, even though they may not be the best lookers. Help is appreciated! A. Burrow or nodule? Found on a trail coming off the Hyden formation. Notice the little hole on each end. 1.5" long, 0.5" wide. B. I know this is a piece of horn coral, but what is that small piece sticking out of the lower pic? Also horn coral? This "appendage" is about 1cm long by 0.5cm tall. C. Odd "fingers." Found in the Hyden formation. Has a little bit of shine. This "hand" spans about 1/3" wide. D. No clue on this one besides being something marine. Found in my driveway gravel (presumably Mississippian origin). Iridescent. The rock is 2cm tall. Now for some things from my previous topic (which unfortunately got no replies): E. An oddly textured rock found in the creek (Pikeville formation). Possibly crynoid or worm burrows? Also bears a small crescent shape (about 0.5cm wide). Rock is about 1.5" tall. F. Another seemingly-marine fossil that I thought looked neat, presumably from the driveway. Rock is about 1.5" tall.
