Help identifying a large fossil Ctenacanthiform Shark tooth from Late Pennsylvanian rocks in Illinois
Joseph Fossil posted a topic in Fossil ID
Sometimes it could be accurately said a fossil hunting trips most intriguing finds are discovered after bringing the fossils home. That's exactly what happened after my Sunday/August/19/2023 trip with @Tales From the Shale at some Late Pennsylvanian rock formations in Illinois. Lots of brachiopod, bryozoan, and pretty awesome Chondricthyan teeth were found on this trip. But it was at home that I accidentally uncovered a pretty remarkable find I would like help getting a Proper ID for. On Wednesday around 10:00PM EST, I decided to break open with a pretty large hammer some of the large rocks I collected to get rid of excess materials around the fossils. When I got to a brachiopod encrusted rock, I decided to split it down the middle to avoid damaging the top. As a precaution (which I'm super grateful now I still do) I always check the fragments with a flashlight to see if I missed something. This time, I checked extra hard and discovered a very fragmentary cladodont tooth tip!!! I was glad I found it, but kinda kicking myself knowing I may have accidentally smashed to bits the rest of the tooth (the tooth was not even remotely visible on the rock's surface and was hidden in the middle of the rock itself). Fortunately, I searched the surrounding fragments and found the rest of the tooth! I looked at and measured the cladodont tooth fragments more the next morning!! The tooth specimen is definitely from a pretty large Ctenacanthiform Shark! I think (based on the number of lateral cusps) it could be from a large Gilkmanius, but I'm not 100% sure!! What do you guys think? @connorp @deutscheben @Tales From the Shale What do you think?- 2 replies

Help identifying some fossil brachiopods, bryozoan, and Chondrichthyans from Late Pennsylvanian rocks in Illinois
Joseph Fossil posted a topic in Fossil ID
On Sunday/August/19/2023, myself and @Tales From the Shale went fossil hunting at some Late Pennsylvanian rock formations in Illinois! It was a pretty productive trip! We found lots of brachiopod fossils and an awesome amount of Chondrichthyian fossils! There are some fossils though that I'm a bit confused on their exact ID and I would like help identifying them? I put and photographed some of these specimens under a microscope and dissecting scope to help with species/genera identification. Here are the various and pretty awesome specimens from the trip I would like help Identifying: Unknown Specimen 1 (A Posible and partial Ctenacanthiform tooth) Unknown Specimen 2 (A Peripristis tooth but not 100% sure of exact species ID) Unknown specimen 3 (I think either Deltodus or another type of Petalodontid) Unknown specimen 4 (@Tales From the Shale helped me identify it as a bryozoan, but I forgot what type/genera he said it was (though he said it was pretty rare), I found at least 2 specimens of this type on this trip) Unknown Specimen 5 (Found on the same piece of matrix rock as Unknown Specimen 4, I'm not 100% sure what it is) Unknown Specimen 6 (some other type of bryozoan, I have no idea what could be it's exact ID) Unknown Specimen 7 (Found on the same piece of matrix rock as Unknown Specimen 6, some other type of bryozoan but I have no idea what could be it's exact ID) Unknown Specimen 8 (some other type of bryozoan, I have no idea what could be it's exact ID) Unknown Specimen 9 (A Possible small Petalodus tooth) Unknown Specimen 10 (A Possible small Deltodus tooth)- 4 replies

This came from the Brad Formation, Palo Pinto County of Texas. It's in the Missouri Series of the Late Pennsylvanian. There seems to be crinulations like you see on crinoid stems but there are nubs poking out in a completely random way in every direction. Some of the surface looks a little like calyx plates but there is no obvious symmetry. It could be part of a holdfast since I am not familiar with them but I have no idea for certain. The scale in millimeters.

This came from the Jasper Creek formation, Bridgeport Shale, Missouri Series. Could it be a brittle star vert? I haven't seen them here before but I'm not sure what they might look like from the Pennsylvanian. Scale in millimeters.

Whatever this fish tooth is, I've never found one before. I had a small sliver showing in a rock and spent over an hour slowly air scribing over it and getting it to this point. I'm hesitant to go much further, as I may break it. I considered Polyacrodus for the shape, but I see none with the pitted pattern that this has. Tired of trying to ID Pennsylvanian fish teeth yet, @connorp? Maybe this is another paver type teeth from a ray, etc. For scale, the length of the tooth in the first photo is 13 mm.

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 underside with scale: Front view with scale (non focus stacked) There is a porous layer on top, which is very similar to crinoids I've seen in the past. I've only ever found stems.

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 here is a close-up of the longitudinal lirae with fine crossing radial lirae. This shows it on the venter of another specimen and here is the largest sample which would have had a diameter of around 77mm without the body chamber, much larger than Agathiceras which I believe can range from 8 to 30mm depending on the species. I would appreciate any help with these.

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.

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 to get in two hours of collecting. This is a great site, and kudos (and THANKS) to the Dallas Palaeontological Society, Mineral Wells Parks and Recreation Department and all others who helped make this great park possible.

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 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...
