This is perfectly circular in cross section. I am fairly sure this is a Tentaculitoid, but I've never really identified one before. These are somewhat rare where I fossil hunt. I've seen a few bits and pieces stuffed inside of gastropod shells. This one was fairly long, with at least another 1 cm of material broken off when I cut it out of the parent rock. It is mostly white in color, but that is more shell preservation at this site rather than an important attribute. Most of the Tentaculitoids in books I've seen have ribbed ornament, whereas this has lengthwise ribs. CG-0616—Unknown Scale bar = 5 mm.

Hello, found what I think are nautiloids and brachiopods. I found the rock in a stream and I can't say what limestone (maybe brush creek or pine creek), but the area is Glenshaw Formation in northern Allegheny County, Pennsylvania. It's quite difficult for me to get good pictures, let alone good pictures with scale, so I'll tell you that the first two pictures are 2 cm (same organism), the second is 5.5 cm and the largest Nautilus in the last pictures is about 6 cm. All information is appreciated, thanks!

Hello all. I am posting a link to a calendar I created for 2023. It showcases twelve different late Paleozoic gastropods I have recovered over the past three years in Armstrong County, Pennsylvania. Eleven of them are from the Pine Creek limestone, and one other comes from the Brush Creek limestone. Each month features a different gastropod, photographed after coating it using ammonium chloride vapor, using an iPhone to capture photos through a microscope lens. The cover photo showcases all twelve, and the images for each month typically showcase an additional view at a much larger size. While this is a color print calendar, all the content throughout is black & white. If you enjoy natural color photos of fossils, you might skip this. I am selling this calendar without profit to me. I am still waiting to receive my copy, and I can follow up on print quality when I get mine. Lulu says this is 100 lb paper, but I'm still determining what to expect. Please PM me for purchase information.

I don't expect this one to be easily solvable. I've found nearly two dozen Petalodus teeth over time, so I have a good idea of what the cross section looks like for the tooth material. The white edges with the canals reaching inward. You can't see it will in the photo but there is a calcite grain structure in the center. This piece was oddly shaped and fragile. It's unlike any of the surrounding rock. There are 4 pieces in all, but this one has the best look. The lumps at the bottom edge are raised and textured like the surface of some teeth are. The scale along the bottom of both photos is in millimeters. Maybe it's just a shashed up Petalodus tooth root. Have any of the Carboniferous shark tooth hunters perhaps seen something similar? This second photo is a closer look at the raised areas. There is a lot of matrix infill here, so again, it will probably be difficult to identify. At the very least, I'll stick the pieces in a box and file it under mystery fish parts.

I found this a while back, but finally saw it as an Ammonoid. But which one I wonder. It is pretty thin. Unseen is the inner umbilical groove, but it’s likely not important for ID. Opposite side is unremarkable.

Possible ID of Trepospira sphaerulata from a local gastropod expert, but he isn’t sure. Similar ones in a group with original specimen at the right. Left is suspect of being related, but it might be.
