This is a tooth I found in Northwest Kansas (Graham Co.). It is 100 percent complete. It looks like nothing I have ever seen before. It has cerrated edges which leads me to believe it is Squalicorax Sp. but I am not sure because of its odd and blunt shape.

Hello! I’ve been on this site for a while now but I haven’t formally introduced myself. I have been interested in paleontology for quite a while and I am hoping to go to KU (Rock Chalk!), for paleontology when I graduate high school. I have lived in Kansas my whole life and thanks to 4-H, I have had the pleasure of hunting all around Kansas. I think my favorite place to hunt has been out in Western Kansas in the Niobrara Formation.

Went hunting in the Tuttle Creek spillway which was mostly a bust (though I may be biased by my every-other-rock experiences at Lawrence and Lake Shawnee). Aside from fusilinids and a couple of indeterminate shells I found a rock with multiple smooth flat round structures (3-4 cm across). The rock had fallen down the side of the spillway so age is likely somewhere in Carboniferous to Permian. It broke apart when I pulled it from the ground. Any have any idea what these are? This shows the side view of one of the structures (top edge on the left side)

Hello, I have a whole bunch of unidentified crinoids I'd like some help identifying. From my guess on the species and the fact that there were all together (as well as the other specimens that came with it), my guess is that these are Pennsylvanian or Permian-aged crinoids from Texas or Kansas. I'm hoping narrowing down the ID would better pinpoint the provenance for them. Here goes. The calyxes all range from 1-2 cm wide. I did attempt to ID them, using resources including this by the forum's @Missourian: #1-#4 I think are all of the same species or at least genus. I'm inclined to say either Delocrinus or Graffhamicrinus, which are similar-looking genuses. 1. 2. 3. 4. 5. This one is a bit unusual in that it seems to have some arm bits preserved, which look like thick spikes. It's a bit crushed but I think based on the calyx pattern it could still be a Delocrinus or Graffhamicrinus. 6. This one has a basal plate pattern like Delocrinus or Graffhamicrinus, but has unusual spines coming off of the radial plates. The following 3 specimens (#7-9) look similar to the above calyxes, but I noticed they somehow seem more globular and rounded. They may be the same genus/species and just variants, or a different genus/species. For instance, if the above are Delocrinus, perhaps these are Graffhamicrinus? 7. 8. 9. The following four (#10-13) are clearly different from the above. Each has a clear infrabasal circlet and stem attachment, plus the calyx expands towards the top, which gives it a more cone-like appearance. These may be Bathronocrinus according to this: http://inyo2.coffeecup.com/kansasfossils/crinoids2.html 10. 11. 12. This one has some proximal arm bits still attached. 13. This next one has very bulbous/swollen calyx plates, which are especially noticeable from the side view. Perhaps a Galateacrinus according to Missourian's diagram? 14. 15. The plate structure is harder to tell on this one, but it has slightly swollen basal plates that form dimples/notches where they meet the radial plates. This is clear on the side profile. I honestly have no idea what this one could be. 16. This one has no plating texture, and I'm thinking it looks like the basal plate of the floating crinoid known as Paragassiocrinus, which is known from Texas. If so, and it is specific to Texas, perhaps I can attribute all these specimens to the Pennsylvanian of Texas as well. 17. An odd specimen, might be a set of basal plates. 18. This seems to be a stem and basal plates. 19. These seem like spines from the anal tube or "umbrella" of a crinoid such as Plaxocrinus (https://www.google.com/search?q=plaxocrinus&sxsrf=ALiCzsbwpZnGPNxgLHUJ4758h1D4GTNkKQ:1669188769957&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjM5sjd5MP7AhWmKkQIHb3vAIkQ_AUoAXoECAEQAw&biw=1257&bih=764&dpr=2#imgrc=atyg4qzOxLWjRM). 20. I'm unsure if this is from a crinoid, but it might be part of a spine. 21. This one I placed separately because the color of the calyx and matrix are different from all the rest, and so it may be from a different locality. Species-wise it looks similar to the first 9 specimens I posted, so it may be a Delocrinus or Graffhamicrinus.

Hello, I found this fossil in South Central Kansas, 20 miles north of Oklahoma border. A pond was dredged and this was found on a sand pile. Could someone please help me identify it?

Found some interesting fossils with my wife and boys yesterday. 1. Guessing these are gastropod shells (all replaced with crystals) 2. I think these may be crinoid stalk fragments 3. Millions of sub millimeter round fossils (and brachiopod) Wife: I found a rock with the wavy sea fossil (bryozoan) and petrified wood. Me: that doesn't make sense, oh, it's concrete. I guess Kansas has so many fossils we use them as filler 4. Not sure what this is and didn't have a ruler handy

Hey all, I found this in the Arkansas River mud right in the middle of Wichita, KS. It was in one piece but it broke when I was tapping a tarantula wolf spider out of its bone home

My son found this rock a while back in the sandbar of a creek bed in Northeastern Kansas. We find all kinds of invertebrate fossils here regularly in/around creek beds, and thought this looked interesting, almost like dinosaur skin? Or some other fossil? I’m 99% positive it’s just some sedimentary rock, as it is cracked on all sides and common in sandbars here, but we’ve never found one like this and I thought it wouldn’t hurt to consult some more knowledgeable people.

I was wondering if anyone would be interested in trading his/her mosasaurus jaw or partial from a site (Either United States or somewhere in Europe). I've got various amount of eurasian pleistoceen stuff, some dinosaurus teeth. Megalodon teeth of great quality too. Please if you know anyone, feel free to contact me!

I found this listed as a cretaceous lobster from the Kiowa Formation in Kansas. I didn't have much success finding anything similar with some quick research, do any of you guys know what exactly we're looking at here?

.7” tooth, Blue Hill Member, Carlile Shale, Jewell Co Kansas. I am not super familiar with the Carlile Shale fauna and I think this is a Cretoxyrhina but I’m not 100% sure I’m correct so I thought I seek other opinions.

I just got back from a trip to Kansas where I found a tooth in the Ninnescah River outside of Wichita. I first thought it was a cow or buffalo but now after researching it believe that it looks more like a Woolly Rhino tooth. Thoughts?

Hello, I recently got this section of fossilized squid pen of the giant squid Tusoteuthis longa, from the Cretaceous Niobrara Chalk of Kansas, USA. It measures about 7cm long. After receiving it I realized that it seemed rather unstable, with small "splinters" flaking off like a fragile piece of wood. I hear it is recommended to consolidate vertebrate bones with something like Butvar B-76, but what about something like this squid pen? I don't know what the material even is. Does anyone have experience preserving these? Thanks.

Found yesterday in the Kansas River. I'm thinking it's probably just a button buck skull cap. Although I really want it to be from an antilocaprid. But I thought its worth the post for me because it's my first part of a skull Ive ever found in the river. But I can't distinguish personally. I'm not the best at telling Kansas river modern stained bones from permineralized bones sometimes too, and I understand if it's unidentifiable beyond cervid even. Thanks

Hello Everyone. My grandaughter is in 4-H Geology and we found this specimen in Southwest Kansas. We have no idea what it is or how to label it for her exhibit box. Any help you could give us would be greatly appreciated. Thank you!

Hello from Kansas. I'm getting back into fossils now that I have a dino-crazy 3 yo. We make regular trips to museums to look at the fossils and my wife reminded me that we should have fossils here in Kansas. It's amazing what we've found on our first few adventures. Looking forward to many more and learning more from the group (as well as admiring all of their finds).

In the Blue Hill Shale Member of the Carlile Shale formation, you can sometimes find concretions that have very colorfully preserved ammonites. The concretions are usually about the size of a golf ball to baseball. They are smacked with a hammer to see if there is something inside, as many are empty. The concretions are extremely hard, but there is usually a weak spot between the ammonite and the super hard limestone. I recently picked up a CP air scribe, so I thought I'd try it out on a "mud ball" that had a little of a Scaphites carlilensis exposed. The outside of the concretion that is light gray is fairly soft. The dark gray interior is too hard to do much with. I found that if I worked on a part for a while with the scribe, a crack finally developed somewhere on the concretion. After working on the one in the lower part of the first photo, I found that it had another ammonite right next to it. This one was a Prionotropis hyatti. After a lot of work removing matrix, finding a couple tiny "extra ammonites" in the same ball, and gluing parts back together I finally arrived at the finished product. The camera does not do the color justice. The purpleish, pinkish, reddish, rainbows just don't show up well, but as you probably gathered from this long post, I'm kind of happy with the results!!

Hi! I joined to help my neice with her 4H Geology project. I was in geology for many years previously but ended that 15 years ago. Now it is her time. We are from around Wichita and have done some Cretaceous hunting in Western Kansas and Pennsylvania in South Central Kansas. We really want to find some plant remains somewhere from the carboniferous! Here we are in Western Kansas earlier this year and some of our finds.

Not sure if these are trace fossils. The rock looks like a cast of the sea floor.

Rod shaped structures with central cavity, shape reminded me of urchin spines. Bryozoan and coral in background. I thought about weathered coral but the structures seem too straight. Smaller rock with similar but larger structure on back.

My name is Jonathan and I just started fossil hunting with my 4 yo son, Gabe. Here's some shells we found at a flint hills rest stop: 1. Cluster of similar shells: 2a. Corals. 2b. Close up 3a. Larger brachiopod (per posts below) 3b. Same rock, probably same type of brachiopod.

I found this maxilla piece on the Kansas River today. I'm thinking it's some sort of pig ancestor, and hoping it's not just an old domestic pig's. But it seems mineralized to me. Also, the teeth are pretty worn so it's hard for me to ID them. I saw this topic And thought it's too difficult for me to ID based on the worn teeth. But maybe someone else here can help? Please let me know if more photos would be of use as well. Thanks in advance.

I recently acquired this nice little tooth from the Carlile Shale of north central Kansas, which I believe is Turonian in age. It looks like Cardabiodon ?venator to me, but I don't have much experience with the genus. What do others think? The tooth measures 27.17 mm along the slant and is 21.66 mm wide.
