When cleaning up rocks I brought home today, I found this little piece that I didn't originally target. It's pentagon shape makes me believe it's for sure a fossil. I've never found anything like it, so I feel like I'm about to get an education here. Perhaps part of a crinoid? Whatever it is, I don't have the experience, yet. Also noticed the indented hole on the top. Maybe part of it, maybe not. It's way too centered I think to not be part of it. Underside. It is convex with a small raised ridge along the edge. Sideways view of the

I'm unable to identify these goniatites from the Finis Shale member of the Graham formation. Found at the Lost Creek spillway near Jacksboro Texas. At first I thought they were just extra large examples of Agathiceras sp. which can be found there because of the longitudinal lirae but I noticed some other differences. These are more evolute as well as being larger. They also have a larger whorl height to whorl breadth ratio at 1.11 to 1 compared to .85 to 1 for Agathiceras. This one shows the larger umbilical diameter of 10mm and he

This specimen from the Finis Shale of Jacksboro Texas is the first example of a Pennsylvanian nautiloid showing part of the aperture that I have found or even seen. Maybe they are common and I just don't get out enough I believe this is Stenopoceras sp. and the attached clam is probably Pseudomonotis beedi since that's the only species of that genus I can't find an image of and the others on the fauna list have ribs that curve away from center. You can help me twice if you can confirm the clam ID and show us your nautiloid apertures for comparison. Outside

I don't know whether to laugh or cry on this one. Found an enrolled Trilobite in my micro matrix. Gave it a nice spa treatment of hydrogen peroxide & got most of the matrix off. And then took a look at it with my dino lite & found that it has almost no head. Thing is maybe 3.5 mm across and the one thing I didn't actually expect to find. No idea if it can even be identified now, but here's the pics anyway. Pics are 45 x magnification. Jasper Creek Formation. Late Pennsylvanian.

I recently went on a collecting trip ending in the Triassic of New Mexico. I collected in four states and covered 6 geologic time periods. I have a number of trip reports to do, and I usually like to have everything identified before I post. However, I am waiting on some brachiopod identification resources (productids), and I want to get this out while I have time (more reports coming as I work on the specimens from each site). This report is on the Mineral Wells Fossil Park. It was four hours out of my way, but I was determined to get there on this trip (my first to the site) and managed

These tiny fossils all have a groove along the long axis. The surface is textured, but not reminiscent of bryozoan zooecia. Are these perhaps crinoid pinnules? Mineral Wells fossil Park, Keechi Creek Shale, Mineral Wells Fm., Late Pennsylvanian (Missourian). Scale in mm.

This came from the Lost creek Dam site in Jack County Texas, late Pennsylvanian. It looks like a valve of something but I don't even know if it's a brachiopod or a bivalve. It is probably crushed some so that doesn't make id any easier.

I thought I posted this before but couldn't find it, maybe it was on facebook. It also seems like I've recently seen something similar but don't know where. Must take better notes...

Hello, I am hoping someone familiar with the brachiopods of the Mineral Wells Fossil Park, TX (Late Pennsylvanian) and vicinity, might recognize this taxon. It looks to me like an Athyrididae. Perhaps Cleiothyridina sp.?. @BobWill ? I also have some Punctospirifer cf. P. kentuckiensis from the same site. Here's the specimen in question. Thanks for any help.

I know figuring out the IDs of bug wings can be very difficult, but if anyone on here can help I'd greatly appreciate it! I've found these and some others (that I put somewhere I would definitely remember) near Humboldt, Nebraska in the Indian Cave sandstone member of the Towne Formation which puts their age late Pennsylvanian to early Permian. To be completely honest I've wondered if a couple of them might actually be leaf impressions, but I'll let y'all help me figure that out.

I've never seen anything similar to this in my hunts over a number of years. I expect someone here can tell me pretty quickly, though. Wabaunsee Group, Late Pennsylvanian, Kansas.

I found this at the Wilson Clay Pit in July of 2015. I'm not sure what it is. Its quite small, approximately 8 millimeters. It doesn't have the look of a crinoid stem or brachials. Is it from a crinoid? Is it possibly a echinoid spine of some type? It is from the Harpersville Formation, Late Pennsylvanian, Virgilian Stage (288 to 286 MYA). The specimen is below. The scale is in centimeters. Any help is appreciated, as always...
