  1. 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 know there's a lot of fossils in that section of the state so I'm looking forward to hopefully finding some decent stuff! Thanks! Caleb
  2. 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
  3. Niobrara Coprolite

    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
  4. 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, we finally found a spot that was not fenced off on the southern border of Gove County.
  5. Help with Cretaceous Sea Piece

    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!
  6. Hunting for the Niobrara Chalk

    This Sunday my father and I were hoping to take a trip to the Niobrara chalk and check that out and see what we can learn from it. Is there anything you guys can relay to me in terms of places to look or getting land permission? I'm just looking to try to find people to call, places to go, etc. just trying to get a feel for fossil hunting outside of the Fort Hays Limestone and Greenhorn Shale. Thank you so much for any and all info, even on just general paleontology in Kansas
  7. Kansas Shark Tooth

    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 anyone have suggestions for helping affix it to the matrix? I would superglue it but don't want the glue to affect the overall appearance of the enamel. Thanks!
  8. 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 "reconstructed" parts, and often from more than one individual. Last summer my wife and I were fortunate enough to find what I call a "typical" mosasaur eroding out of a chalk wall. What it consisted of were a few scattered broken bones, and when we dug back into the bank a few articulate verts. There was some "root rot" going on, and we decided to expose the bones, pour a plaster jacket on them and extract them this way. They were way to fragile to try and remove individually. When I got them home, I decided to make a mount showing how they were found and tried to capture the excitement of the find. Here is the slab after cleaning down to the bones and plaster. Sitting loosely on the slab are some of the bones we found as float on the ground.
  9. Niobrara coprolite with marks

    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 this one that also has very similar marks, though not as noticeable possibly due to it being badly weathered and a surface find. I may have posted this years ago, but since people come and go on here, I thought I'd give it another shot. Ramo
  10. 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 completely wrong. Forgive me for not being more educated in Mosasaurs. Does anybody have suggestions for the ID? I just finished trying to reconstruct it myself but my star bond bottle decided it wouldn't seal and now my hands are covered in superglue. I've decided to come to the forum to see if there are any experts out there willing to do a clean and repair job on my tooth. No, it's probably not valuable, but it holds significant sentimental value since this is my first tooth find. I think i gathered all the major pieces to do the job but I feel under-equipped and do not feel like I have the experience to be able to put it back together. Before successfully gluing myself, I was able to put some much-needed glue down on the broken surfaces of the tooth and the tip of the tooth. Now, I think it's stable enough to be shipped if necessary. It'll come with 10 coin envelopes for the connecting pieces. Any help or or suggestions for who may be the best person to contact would be greatly appreciated! Thanks so much!
  11. Hello everyone, In anticipation for my trip to Kansas next week, I wanted to see how ya'll would recommend prepping specimens in a chalk matrix. I'm hoping to find some fish bones, vertebrae, and teeth if I'm lucky. I previously was able to scrape and scratch matrix off some stuff I found the last time I went with a carbide-tipped scratcher and I also used my water gun to blow matrix off of the fossils. I found some neat pyrite concretions too and was able to use dilute HCl to nicely dissolve the matrix away but wanted to avoid doing this on fossil specimens since I didn't know if the fossils would also be dissolved away. I was recommended using dental picks to remove material from the fossils since the matrix is so soft. Is there a better way to do this since I don't have pneumatic or electronic prep equipment? Thanks for your help!
  12. 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. Previously, I was lucky enough to find a near-complete Cimolichthyes jaw and some other large fish vertebrae. I know I can re-visit that same site in an effort to find other fossils but I thought I would reach out to Kansas veterans to see if anyone else has suggestions of locations to visit. From reading some of the other threads, it sounds like Castle Rock is a fairly popular destination for public hunting, but I have a feeling after all these decades that there might be other spots that have been less picked-over. I'm looking to find anything and everything but would especially like to find a few teeth. I have relatively little diversity in my current fossil collection. Thanks in advance for your help and guidance!
  13. Hello TFF, I recently was able to glue this specimen together after its discovery this past fall. I need help with identification. It was found in the Niobrara in Logan Co, Kansas. After asking a tooth expert, he hypothesized that it is a Hesperornis. I've done a little research myself and I am not convinced of his conclusion. Of the Hesperornis pictures I've seen online, it appears that the top jaw lacks teeth at this part of the jaw, whereas my specimen is full of teeth. Additionally, there are two rows of distinctly different teeth on both the lower and upper jaw. One set is larger, more spaced teeth approximately 3mm apart and up to 4mm wide at the base. The larger teeth have all broken slightly and look like little volcanoes protruding from the jaw. The second row of teeth in the same jaw contains much finer and closely spaced teeth - about 0.5mm apart, 1-1.5mm wide, and about 2-3mm long. The two rows of teeth are slightly angled from each other - about 20 degrees or so. Any suggestions? I got a second opinion: Cimolichthyes...? What do you all think? Thanks for your help!
  14. Platyceramus Or Inoceramus?

    Hi all, I found these recently along Colorado's front range in the Niobrara Fm, about 20 mins southwest of downtown Denver. I am familiar with inoceramus, but these pieces have ridges - something I didn't think inoceramus had. They also have a similar cross-sectional structure with aragonite as the inoceramus fossils I've found, which makes me think it's some other type of clam or bivalve, maybe platyceramus? The largest piece appears to have small attached bivalves. Thanks for your help!
