Identification Cretoxyrhina teeth are simple in design, having a triangular crown with smooth enamel and non-serrate edges, a thin lingual dental band, rounded root lobes, a lingual root protuberance, and no nutrient groove.1,2 Comments This tooth is from a latero-posterior position, given the crown's distal curvature. The chalk preserved this tooth very well - the enamel retains a sharp gloss comparable to that on modern sharks' teeth. References 1. Bourdon, Jim, and Michael J. Everhart. “Analysis of an Associated Cretoxyrhina Mantelli Dentition from the Late Cretaceo

Getting Permission from Landowners regarding Western Kansas
JFPennsylvanian posted a topic in Questions & Answers
Hello all. I try and go fossil hunting as often as possible and I really want to get back out in the Niobrara chalk in western Kansas. I’ve only hunted out there one time on a state 4-H trip and it was the most fun I’ve ever had. However I do know that most of, if not all of the land the chalk is on is owned privately. I’m not sure the best way to get in contact with landowners about asking permission. If I lived closer I would just drive out there and ask around, but I live in eastern Kansas so it is a minimum 5-6 hour drive out there. Is there any reliable way of figuring out who owns land a -
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.

Hello all! I managed to secure access to some private land in Gove County somewhere near to Monument rocks. The peoperty has plenty of the chalk canyon type outcrops to explore and I couldn't be happier! I won't make it out there this summer but hope to next summer. I had a few questions that I hoped you all could help with, or point me in the right direction before I head out there. One, I know that the chalk is notoriously difficult to determine stratigraphy in. The chalk I have access to is both higher than and lower than the capstone on Mon

A gorgeous tooth from one of my favorite sharks! The enamel isn't polished - the chalk preserves its shine extremely well - it's as shiny as when it fell out of the animal's mouth! -

A beautiful tooth from one of my favorite sharks. This one is extra special because of the self-inflicted bite mark - a gash seen on the left in lingual view. Apparently their bite was strong enough to cut their own teeth! -
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 li

Dear Forum members, A few years ago I bought this piece from a fellow collector. The description mentioned that it is probably a Platecarpus sp. atlas and axis vertebrae, Niobrara Fm. Gove Co. Kansas. I think that this is acutally the supraoccipital, epioccipital, basisphenoid and several other skull parts. I do not know if this is indeed from a Platecarpus species? if so, which species could this be? I'd like to know whether this piece is Coniacian, Santonian or Campanian in age. Perhaps the preservation already can point in a direction. the fossils are all very flatt -

Cretoxyrhina mantelli Ginsu shark Niobrara Fm., Gove Co., KS (leftmost 2 teeth) Eagle Ford Group, Sherman, TX (largest tooth) Eagle Ford Group, Dallas, TX (rightmost 2 teeth) A collection of teeth from a formidable Late Cretaceous lamniform shark. This species competed with other sharks and marine reptiles in the Western Interior Seaway ~ 90 Ma. It likely filled a similar niche that the Great White Shark does today. The ginsu was on average larger than the Great White. Oh, it also ate dinosaurs. -

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 relat

Are these platecarpus vertebra fake?
JojoMozza posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi there, I purchased these from a dealer and was working if this is genuine. If anyone can help me, it would be much appreciated :D. The dealer said that it is an articulate set of Platecarpus vertebra from the Niobrara Chalk, in Kansas. I will attach more photos below Thank you! -
So my son and I were walking in the Niobrara river west of Verdigre, Nebraska and found some fossils. These were the best 2 that we have. Also found a lot of bone fragments. Any help in identifying these would be great. I have no idea. Thanks in advance. Tom

Hi Everyone, I suddenly have a work trip to the Black Hills of South Dakota coming up next week and I'd like to get out and collect some fossils along the way. I'm driving from Denver to Lead, SD and will be driving north on HW 85 and 18 through Newcastle. I'd be really happy to get a few stops in along the way and any potential information would really be great. Unfortunately, I won't have a ton of time to be able to stop and really dig, so some road cuts or target formations would be super helpful for surface collecting. I'm open to every type of fossil.

I don't know if any of you caught this article in Eurekalert or elsewhere. A Niobrara formation fossil found 70 years ago was studied by isolated experts over time. It was first identified as an algae, then a cephalopod, and now as a cartilaginous fish! Ah, the Internet makes it so much easier now... https://www.eurekalert.org/pub_releases/2018-04/amon-faa041618.php

I am wondering if any more information can be gleaned from this specimen beyond "coprolite". Bony fish? Shark? Mosasaur? Niobrara fm., Cretaceous. NW Nebraska. @GeschWhat

This past weekend, my dad, brother and I were able to go out to Western Kansas to search in the Niobrara Chalk formation. We live in Manhattan, KS, so we had to drive about 4 hours to get to a suitable spot. A lot of Western Kansas is private property, so we had to look up GIS maps for Lane and Gove counties, which is where we wanted to search. Sadly, when we got there, one of the roads seemed to not exist; our map led us through the middle of some farmer's cornfield. It wasn't blocked off, but we decided not to take our chances. We started to look around in the area, and about an hour later,

I have been talking snarge with GeschWhat, and sent her some pictures of two coprolites I have collected over the years in the Niobrara Chalk of western Kansas. I have shown these to a few people, and nobody seems to know what caused these strange marks. The one that is marked a lot was the first I found. It was sticking out of a chalk cliff about 5 feet above the floor of the valley. The marks were on the parts of it still in the chalk, so there is no way they were added after fossilization. Years later I found another similar sized coprolite, also in the Niobrara but not associated with

Hi all, I was inspecting some of my Smoky Hill Chalk finds when I stumbled across this. It is inside/on a partial Inoceramid, most likely Volviceramus grandis. This was all in the Smoky Hill Chalk, Late Cretaceous. Thanks for any suggestions!

I found this shark tooth yesterday in the first chalk bench of the Fort Hays Member of the Niobrara approximately one foot off the contact of the Carlile Shale (my first keeper from the Niobrara). I was able to prepare it as best I could this morning and realized it doesn't have a root. This was my first matrix prep of a fossil and I'm pretty pleased with how it turned out. I was hoping someone could help me identify it. I think the photos look at the lingual side of the tooth. Also - since it's imbedded in chalk, it is beginning to separate from the matrix. Does anyo

Back when I first started fossil hunting, I researched all I could find for stuff around my area. I went to museums, and looked at a ton of pictures. What I found were awesome complete mosasaurs, plesiosaurs, fish, etc. I went out expecting to find something like that. What I found were scattered pieces and parts of stuff. I had no idea that most of these awesome finds I saw in museums were not dug up looking exactly how they looked on the museum wall. The fact is, was most of these things we see in museums are from individuals scattered along a big area, made up of at least some "recons

TFF, Yesterday, I was fortunate enough to find (what I consider) a tremendous tooth specimen in Gove County, KS. Unfortunately, plant roots got to the tip of it before I could and because I was a space case and didn't bring superglue, the tip and about 10 other pieces connecting the body to the tip fell away when I excavated it. It's relatively long and straight over its length and it appeared to be separated from the rest of the remains. I tried navigating the Oceans of Kansas site for researching what it belonged to. My first guess is Tylosaurus but I could be comple

TFF, After about 10 months, I am finally scheduling myself to make another trip to western Kansas next week - 8/27-8/30. I am conducting field work for my master's thesis which focuses on outcrop modeling and interpretation of Niobrara fracture systems using a drone. I feel fortunate that one of my field areas is famous for its abundance of preserved Cretaceous fauna. While I'm out there, I figured I would try to make an effort to visit some well-known fossil localities that have public access or find private landowners that are also enthusiastic about fossils.
