This is from the middle Pennsylvanian. Appears to be fusilinids in pink-red sandstone with several orange passengers onboard. They all appear to be centralized to a broken open fusilinid. Only one big enough to really get a couple macro shots of. Any ideas on the orange item? I didn't want to put too much pressure on it, but definitely quite hard (scratch resistant to a needle). 33mm x 25mm" as pictured. Orange unknown is 2mm.
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)?
icycatelf posted a topic in Fossil IDI 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?
