Recently I purchased these two Squalicorax sp. tooths from an auction website and both are currently on the way. I have a few questions about identification since I know very little about shark tooths and also please correct any misidentifications. Seller A sold me this tooth and it was listed as Squalicorax hartwelli. It is collected from Niobrara formation in western Kansas. Is Squalicorax hartwelli considered a variation of Squalicorax falcatus? Do you agree with seller A's identification above? Seller B sold me this tooth and it was listed as Squalicorax kaupi. It is collected from Lincoln Limestone member of Greenhorn Limestone formation. I suspect this tooth is misidentified and it should be Squalicorax falcatus, a paleobucket taxa for Squalicorax sp. variations. I thought Squalicorax kaupi is found from Santonian to Maastrichtian and Lincoln Limestone member is Cenomanian. I spent quite a bit looking up on here and Ocean of Kansas website comparing Squalicorax sp. tooths before posting! Although I am more confident in some of the members' identification skills than I am with mine. Regardless of identifications (or misidentifications), I am happy with both and is excited to have them arrive soon!

Hi I recently found this big intact fossil while hunting in North Central Kansas. It's about 18 inches long. It is covered in smaller shells and has one small whole in shell that you can see in pictures. Is this a giant clam? https://photos.app.goo.gl/MMEEuEbGHe4x9a1YA

At first I thought it might be the cross-section of petrified trunk but upon a closer inspection, I doubt it's petrified woods. It is not silicified. I wonder if it's a concretion or Liesegang rings? I don't think I have seen something like this in person before. I couldn't get it extracted because it's embedded in the bedrock.

I'm wondering if it's really the petrified woods. It's found in ironstone concretions from Dakota Sandstone (Cenomanian), and it strikes me as 'woody'. I'm interested in what others think. From different trip and different site few months ago, but same formation and age.

Finding the fossilized leaves from Dakota formation (also known as Dakota Sandstone) has been one of my goals for a long time. Today I headed to Ellsworth County, Kansas, where the Dakota Sandstone are located and hunt for the fossilized leaves. Unfortunately it's mostly a bust, but I did find a couple possible wood fossils and a few interesting rocks. I didn't take anything home this time except some pictures and memories. Notice the trees following along the small stream. Interesting sandstone! Interesting ironstone concretion! ...Continued on the next post.

From my previous trip to Ellsworth County, Kansas and it's located in Dakota formation, Cenomanian. It appeared as almost like vertebrae but I'm sure it's not verts. Is it by chance some form of ichnofossil? @jpc thinks it's concretionary. No disrespect to him, he's the only one who offered his opinion and I would like to know if anyone else have a different opinion.

Like what title said: is it a tree limb, bamboo, reed, or is it even something geological? Dakota formation, also known as Dakota Sandstone. Dakota formation is known to produce variety of flora fossils, such as leaves and seeds. The patterns on these fossils strike me as 'flora-ish'; like these that seem be nodes and also 'bark-like' and fibrous textures. ...Continued on the next post.

Today I had a good time with fossil hunting at the Dakota formation (early Cenomanian) sites and Greenhorn formation (Cenomanian-early Turonian) sites in Ellsworth county, Kansas. Typical view of the local countryside, but still beautiful! I keep finding these weird vertebrae-like rocks, clustered in this particular site and not other sites. I suspect it's not vertebrae but I still can't figure this out yet. These mysterious vertebrae-like rocks...reminds me of shark centrum and crinoid stems but I don't think it's them. This site is Dakota formation. I took these home just in case it is identified as fossils later. I think it's fossil vegetation of some sort. Maybe reed or horsetail? I found these jumbled at different locations but put it together and it fitted like a puzzle. I took it home and will be prepped. This is from Dakota formation. Inoceramus from Greenhorn formation. One of the best specimen of this genus I have found so far! Took this one home. Another Inoceramus, pretty good specimen! I also took this one home. Tiny fossil in the center. Greenhorn formation again. This tiny fossil, image enlarged and the ridges/grooves are visible. No idea what it was. I took this one home and will be put under the microscope for identification efforts. The storm was brewing at the distance as the cold front is heading south. It was lightning and I was at near the top of hill, the road would be impassable if wet, so it was time for me to go home! I will be posting some of those fossils on the Fossils ID section soon after it is cleaned up. Cheers!

Hi, I was wondering if these jaws were fossilized, they’re for bid as Pleistocene but they looked kind of modern.
-
Is this even a fossil? Ichnofossil? I'm stumped by this weird pattern. I found this ironstone in my parents' gravel driveway. Gravels were recently obtained from the local sand pit company here in Salina, KS., so I'm pretty sure this stone was transported in the river from Kiowa or Dakota formation (Albian) before being deposited.

Found this one at a local antique store. The owner claimed that it was a tooth that their aunt had found near Salina, Kansas. Wish I had more information for you, but thats all I got. Any help identifying it would be greatly appreciated.

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?

About a week ago, I was visiting relatives in Western Kansas and was taken to a very small exposure of Upper Niobrara chalk on the family farm. I have been hunting in the area for many years and I had never paid any attention to this particular location. I did not see much material that was worth picking up, BUT then..the unusual texture of this particular "stone" caught my eye. Because the exposure consisted of a few feet of the Upper chalk covered by a thin veneer of sand and gravel (Ogallala?) and then the top soil, I am not at all certain of the geologic age of this specimen. The relative absence of wear does not suggest that it was transported with the sand & gravel, BUT I have NEVER heard of any fossil sponges (or coral for that matter) from the Smoky Hill Chalk. I would VERY much appreciate your suggestions as to the age & identity of this find. Dave

Found in Kansas, on surface in wooded area, moss covered, under a tree next to poison ivy. Did glance around to look for possible connecting pieces but did not espy. Top looks like a turtle. Am wondering if the bottom is also because of markings that don't seem like random impressions. Am still cleaning with soft toothbrush and white vinegar in a Zen like fashion. Tiny black balls on surface that aren't budging. Textures emerging. There is an area near the top part which I'm wondering if it is it's head. Hard to photograph end to end details well.

It's pretty obvious to me it's a fossil tooth: but from what? Kiowa formation and Albian. Approximately 1.1cm long.

How do you differ between bony fish vertebrae and shark vertebrae? What about these three vertebrae from Kiowa formation (Albian)? #1: approximately 5.5mm wide and 3mm thick. #2: approximately 5.5mm wide and 2.3mm thick. #3: approximately 4.8mm wide and 2.3mm thick.
-
Kiowa formation and Albian. Approximately 1.3cm long and its quite flat and thin. Not sure if it's brachiopod, more specifically a lingula brachiopod, or a bivalve. Unfortunately the umbo is missing so I'm not sure if it's symmetrical or not. I'm leaning more on bivalve but I would like to read your opinion. What's the lowest taxonomy level you can identify?
-
A fragment of something; I thought it might be a part of fish spine or decapod pincer. From Kiowa formation and Albian. Approximately 5mm long.

All from Kiowa formation (Albian). Identifying fossils from Kiowa formation has been incredibly challenging for me the last few months and I would need help on here! These possible fossil fragments have features that made me have second thoughts on whether if it's just suggestively rocks. They are suspiciously of biological origins, but I would like your opinions. #1: approximately 3mm long. It's quite smooth and featureless with some mineral staining. #2: approximately 10mm long. top view bottom view and it's fairly flat ...Continued below.

It appears to me as a pyritized wood, it gave off the metallic sheen when it's under the light. Pyrite/marcasite are abundant at where I found this and it's from Kiowa formation (Albian). Kiowa formation is primarily an estuarine and shallow sea environment, fossilized wood and plants are occasionally found from there. I found it as a concretion but it crumbled into tiny pieces when I pulled it out of the ground, so this one is the largest and only piece I have now. Do you think it's a pyritized wood?

Receiving this gorgeous but mysterious specimen is from Upper Pennsylvanian limestone dated around 290-300 million years ago from somewhere around Kansas City. Looks like a tooth to me and my best guess would be orodus? But I have little experience with Pennsylvanian shark teeth in general and especially from this area, also cannot find a comparison elsewhere online. Any help will be appreciated.

I try to identify any fossils on my own before I post it on here, that's how I learn! Anyway, I found these three shark teeth while pre-washing the matrices from Kiowa Formation (Location: Ellsworth county, Kansas. Age: Albian). A couple of them came loose during pre-washing and I found another one still in the matrix. Tooth #1: Is this tooth from Meristodonoides sp.? The views are from front and back of this tooth. Approximately 2mm long. Tooth #2: Is this also from Meristodonoides sp.? Approximately 3mm long. Tooth #3: Is this from Leptostyrax sp.? Front and back views of this tooth. Approximately 6mm long.

I named this topic as Fish tooth #2? because this fossil is very similar to my another fossil in a previous topic a while ago. Nobody really have any consensus on what it is and I thought it might be a fish tooth. I hope I will be lucky this time to have someone identify it for me with confidence. Located in Ellsworth county, Kansas, age of Albian, and from Kiowa Formation. It's approximately 4mm long. I know identifying specimens from Kiowa Formation can be a real pain since it's so little researched! lol...

I found these that resembles burrow or root cast in Ellsworth county, Kansas, USA from my previous trip. The formation these came from are most likely Kiowa formation/Kiowa Shale and the age is Albian. Here's the link to my previous trip. I'm just catching up with the prepping and sorting my fossils from my previous trips. I am wondering if it is some sort of ichnofossils. Is it burrow, root cast, or something else? Also, is it possible for it to be from geological origin rather than a true ichnofossil? This one is the largest I found. The center is poorly cemented sandstone and can be easily brushed off with a toothbrush while the outside layer is hard. Notice the winkles around the interior bend. The measurement is in inches (I know I need to get a metric system badly, my apologies!)
