Found in Martin Kentucky, Middle Pennsylvanian, Hayden Formation. I thought I found a geode the other day so cut it open. The surrounding material got a somewhat mirror shine from the cutting tool (I assume iron rock). However when I hit it with a hammer and it cracked open I found this inside. It looks, to me, like a small fish or plant. I have no idea if this is even a fossil, so any help would be wonderful. Thanks in advance.

Wandering about I found some slivers of porcelain like permineralized material floating on the surface in a small dry wash. Exposed and opened a small trench of very broken up pieces of a Lycopsid. I'm going to very tentatively guess Sigillaria due to presence of crenulations on the remaining margin of the material. Covered the pocket back up after taking a few photos. The overall pocket length was at 3 feet when I quit. Specimen increasing in size and going deeper into the hill than my little digging knife could handle. Nearby plant roots had entered the specimen and succeeded in breaking it up into chunks. In this photo one can see areas of black, red and pink surrounding the exposed permineralized specimens. Learning questions: (1) I'm going to guess this is degradation of the former exterior? (2) Colors suggest iron content and/or maybe some carbonization? (3) Are there some papers whereby I can learn more characteristics to help narrow down otherwise hard to ID Lycopsids?

At first sight out in the back country I thought I had stumbled on some calamite sections. After cleaning up some specimens at home, I am now leaning more toward some other Lycopsid. Perhaps Sigillaria? @paleoflor More photos to follow

I recently got to do some hunting in northern Missouri, Marmaton group and found a few large phosphatic concretions. Within one was this specimen that I am trying to identify. I am wondering if it looks like a Solenochilus sp. to anyone beside me? There may not be enough of the specimen present to determine a species ID, but I figured I'd take a shot for the sake of labeling. Thanks,

These are from the Middle Pennsylvanian (Beeman) in southern New Mexico. 60mm seam of limestone embedded with gastropods. So deeply embedded and oriented as to make identification more challenging. Guess: Bellerophon * Surface is not smooth. * Appears to be symmetrical. * Ridge along the midline. Larger hash plate. Each of the larger gastropods is approximately 25mm. This plate is 220mm x 270mm at widest measurements. Smaller hash plate View of side of larger hash plate Ridge Aperture Another ridge It's my intent to prep on these two slabs while I hide from the heat during the hot months here in the desert. At least an approximate identification would be quite helpful so I have some idea of the shapes I will be trying to reveal.

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)?

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?
