  1. Hi everyone, I missed the updates for the last three days so here they are. I spent the last 3 days of the week fossil hunting the Hell Creek badlands of North Dakota- In those 3 days I found some of the best fossils in my collection so far. Wednesday was somewhat overcast which kept the exposures from being too hot. I spent the morning working a microsite with a few other people. My best finds here included a nice quality croc tooth, a likely bird bone and a bowfin jaw. Unfortunately the finds started to fizzle out after about an hour. The rest of the day was spent prospecting a wide open area which provided very little for fossil finds, the best being a croc vert. Here are the pics from Wednesday- Bowfin jaw section Croc tooth Likely a toe or limb bone A view of the microsite A croc vert A view of the area we prospected A rattlesnake in a burrow which I spotted at just the right time. I was moving closer to look at a large shed snake skin and saw this guy in a hole underneath the grass, he didn't rattle at me either which makes this a lucky encounter. (I didn't this close with my camera, I only zoomed in with it).
  2. Petrified Wood

    Hello, I just joined and am curious about my petrified wood! I live in North Dakota. I have a lot of it over many acres however mine looks different than a lot I look up. It’s more light gray dark gray black and white. Any info would be appreciated.
  3. Mystery item found in western ND

    Hi everyone, I came across this object earlier this evening and I was wondering if anyone could help me figure out what it is. It was found embedded in a soft rock (soft enough to scrape away large chunks with a pocket knife) with just a small cross-section exposed. It first grabbed my attention because it appears round and hollow in cross-section, and was a different color and harder than the surrounding material. The rock it was found in was at the top of a hill, and located in western North Dakota, just barely across the border from Montana. My friend and I tried to brainstorm what it could be, but everything we could think of didn't quite seem to fit. If anyone has any ideas, I'd really appreciate it! Also willing to accept that it might just be a weird rock... Thanks! (More photos to come in the comments)
  4. Very cool article on a Hell Creek Fm bonebed in Bowman, North Dakota A meteor impact 66 million years ago generated a tsunami-like wave in an inland sea that killed and buried fish, mammals, insects and a dinosaur, the first victims of Earth’s last mass extinction event. The death scene from within an hour of the impact has been excavated at an unprecedented fossil site in North Dakota.

  7. North Dakota fossils?

    Hello, I will be going to visit kin up in Ottertail county Minnesota over the 4th of July week. We are coming up from Florida, and have some relatives towards Ashley/Napoleon as well as in Minnesota Despite visiting MN/ND repeatedly throughout my life, I know almost nothing about fossil hunting possibilities, aside from the famous Badlands finds...my focus has always been on fishing and such, but my 5 year old is high on fossiling (and has quite a collection from Florida already) We are flying in from Florida to the Cities and driving out west. IF any of y'all have insight on: 1) locations in Western Minnesota or Eastern North Dakota (Jamestown, GF, Fargo, maybe out to Bismarck) to look for fossils 2) locations between Fergus Falls and the Cities 3) guides or trips we could participate in 4) fossil/dinosaur related sites to see in that part of the country 5) tips on applicable laws we should be aware of ...I would be GREATLY obliged Thanks y'all very much in advance
  8. Detroit Lakes??

    Hello, I will be going to visit kin up in Ottertail county over the 4th of July week. We are coming up from Florida Despite visiting Minnesota repeatedly throughout my life, I know almost nothing about fossil hunting possibilities...my focus has always been on fishing and such, but my 5 year old is high on fossiling (and has quite a collection from Florida already) We are flying in from Florida to the Cities and driving out. IF any of y'all have insight on: 1) locations around ottertail county/detroit lakes 2) locations between Fergus Falls and the Cities 3) locations in EASTERN North Dakota 4) guides or trips we could participate in 5) fossil/dinosaur related sites to see in that part of the country 6) tips on applicable laws we should be aware of ...I would be GREATLY obliged I reckon anything between MSP and Jamestown ND would be reasonable, bu the closer to Fergus, Alexandria, DL, etc., the better! Thanks y'all very much in advance
  9. Hi there, I'm new to the fossil forum, and was hoping I could get help in identifying this jaw. It was found in Marmarth, North Dakota in the Hell Creek Formation. I don't have any more specifics on location besides that. I hope the pictures are detailed enough, but if not, I can post more. I am thinking it has to be some kind of fish, but I am not completely sure. Any direction or help would be wonderful! Thank you so much!
  10. Is this coprolite?

    I need help identifying this. It was in my childhood rock collection. It looks a LOT like some of the corpolite pictures I see online. Does it look like that to you all? It probably came from central North Dakota since that was where I lived, but even that I'm not sure about because we did go on family trips to Montana, and sometimes South Dakota. So it could possibly have come from those states as well. Anybody have any ideas what it is?
  11. Hell Creek Coprolites

    Hi all, I just got back from a fantastic dig near Marmarth, ND. I was in coprolite heaven! I am wondering if anyone has any clues about the round inclusion in the first photo. It is phosphatic. I thought it was particularly interesting because I rarely see inclusions in this type of coprolite. I am also including photos of some of the more interesting coprolites I found along with a really cool ichnofossil found by another member of our group. What is interesting about this one is that it is furrowed on both the rounded and concave ends.

  13. On a popular internet site is this absolutely gorgeous tooth out of the Hell Creek Formation in North Dakota. The tooth is perfect and the colors are stunning! The problem is that it is being sold as a juvenile T.rex tooth, and it is clearly a Nanotyrannus tooth. If it were priced at $300, I'd snatch it up in a heartbeat. Description says that it is too robust to be a Nano tooth. . Notice no picture of the base of the tooth is shown in the listing, so it's difficult for one to be 100% certain. Size is only 1.26 inches.
  14. Is It Bone

    Another piece from Burleigh county. There is a large hill of ice thrust Fox Hills formation at this site, parked on top of Cannonball formation and Bullion Creek and covered with glacial debris. Fox Hills is a near shore marine formation. The others are terrestrial. The surface texture looks like some of the bones I have seen here, but the inside of the rock seems wrong for bone. It is 31 mm long. 20 mm high, and 22 mm wide. Photos are top, bottom, and side view respectively.
  15. It's A Bear!

    I'm pretty sure that this is the lower left 1st molar of a Short Faced Bear, but an expert opinion would be appreciated. Thanks in advance!
  16. Hello, Thanks for looking at this post. I have my Grama's Fossil Collection. She lived in Western North Dakota/Eastern Montana. She found this around the farmland. Hopefully someone can give me a little more information on them. The general area is inbetween Beach North Dakota and Wiboux. I'm not really a collector so I don't really know what is important. I can re-photograph any of these with different light or angles or closer if need be. I really appreciate your help. I would love to display some my Grama's collection but would like to be able answer questions if anyone asks. I couple of the photos are of the same fossil from different angles. I'm not sure the Scoria (redish one) is even a fossil but it was in Grama's Collection Box so I thought I would post it. Thanks again, Steve
  17. Is This A Dinosaur Egg?

    My husband found this at q job site in North Dakota. Is it a dinosaur egg?
  18. Over the next few days I'll be moving from Tulsa, OK to Williston, ND for my job. My approximate route will be taking me through Oakley, KS; Rapid City, SD; and finally Williston, ND. On my way, I was hoping to make a stop in the Niobrara chalk near Oakley and then make a visit to Mount Rushmore in Rapid city, but other than that, I haven't thought of any other good stops. So, if anyone has any good suggestions for stops ( for fossiling or otherwise) or advice on hunting the chalk, your input is greatly appreciated. I'll be trying to post the pictures from my trip on here as I go, but they will get on here eventually. Thanks again everyone, -Peter
