  1. Continuing from my recent trips to outcrops of the Cannonball Formation I made my way South towards the area of the Cannonball Formation type locality. I stopped at a couple roadcuts in Morton County on the way down but spent most of the day on the Cannonball River in Grant County. A burrowing owl off a country road. I believe this is Escobaria missouriensis among Cannonball sandstone. It isn't one of the species of cacti I frequently see. The only fossil that came from here is Nototeredo globosa bored wood(?). Pictures don't properly sh

    North Dakota Dinosaur Egg?

    While doing yard work, this rock caught my eye because it looked like it had fresh blood on it. I cleaned it up a bit, but there are about 5 or 6 holes with dark red dirt coming out of them. Could this be an egg? Thanks.
  3. I was eager to get out before the heatwave coming up so I made the visit to a couple new Cannonball sites the other day as well as property adjacent to where I collected the crabs this spring. I was expecting more good bivalve material from the first sites but I'm pretty happy with the results regardless. Sort of a continuation of this topic. I tried a few cuts before working my way down to the area I found the concretions in before. The material in all was extremely fragmented. I still need to bust that concretion. One of the inconspicuous cuts. More fragments.
  4. I'm looking for a copy of Vertebrates of the Cannonball Formation (Paleocene) in North and South Dakota Alan M. Cvancara & John W. Hoganson Journal of Vertebrate Paleontology Vol. 13, No. 1 (Mar. 18, 1993), pp. 1-23 (23 pages) It's on Jstor but isn't currently available for free online reading. If anybody has a PDF I'd appreciate it.
  5. I just returned to the site I mentioned in my previous Hell Creek trip report to give spend the day digging and exploring to see what else was left behind. I also stopped at another property in the morning that I recently obtained permission for. The first site was beautiful and, despite the sparse fossils, was a fun way to start the day. Lower in the layers some very sparse and fragmentary fossil shell material was found but it was really too fragmentary to collect or even get a good photo without bringing macro lenses. The lower portions did transition int

    Reptile Skin Fossil?

    What is this fossil? It is a hard rock found in the bottom of a creek that happens to be very low around the Bismarck, North Dakota area. It looks like some sort of reptile skin. The size is about 1 1/2" x 3/4".
  7. The weather was nice so I decided to get out to a couple sites that were on my list. The first site is the site where a friendly pocket gopher throw up fossils at an otherwise barren spot. Only one pocket gopher mound had fossils. The nearby ones apparently never made it to the layer of Fox Hills strata, even the ones within a few feet of this one. An unassuming site. The fossiliferous pocket gopher mound. This time the conditions were fine for sieving so I proceeded to sieve this gopher's pile. Lots of shell fragments but also some more complete stuff. I ra
  8. To make a long start to a story short, due to work connections of a relative I recently got invited to excavate a dino on a property. I was quite unsure what I was dealing with until I got there. Aside from the fact this was my first real foray into that part of Hell Creek territory there was a lot that wasn't clear; how well preserved was it? Is it better left to left professional hands? Was it within my ability to excavate (how was the rock, how large was it, etc.). Because of all this I ended up making the 4.5 hour drive to Bowman County with the simple expectation of scouting and seeing wh

    Fox Hills Shark Tooth: ID Requested

    I've collected another Fox Hills shark tooth and I wanted to see if anyone more familiar with Maestrichian shark species has any ideas on what it may be. Attached is a preliminary list of species present in the Fox Hills of North Dakota as reported from Hoganson in 1995. There have been additional species discovered since that are present in a recent publication but I don't currently have access to that paper. I do have experience with some of these from other Cretaceous deposits but I welcome input from anyone with ideas. Pictures of the specimen. It has been difficult to get clear
  10. A few weeks ago I had the opportunity to look for fossils among additional Pierre Shale outcrops in the Sheyenne River Valley. I didn't post anything about that trip as it came up a bit short and read like my last Pierre Shale trip with more partial specimens. Today I went back to the area to look again, and also made it to an outcrop of the Gregory Member. Low water levels made for a great collection from the Gregory. The DeGrey was rather typical. The side of one of the so-called "Indian Mounds" of the DeGrey member and a frog which was hanging out on the mound. This p
  11. Hey everyone! I know it’s a long shot, but I’m currently in Montana and will be for abt 1 1/2 more days, and was wondering if anyone had any ammonite sites in Montana, South and North Dakota, or Wyoming, I’d be willing to trade a spot, or take whomever it was out to Ernst quarries, or trade fossils for the site, if anyone’s interested in that, please let me know.
  12. Went to attempt some new sites in Emmons County North Dakota yesterday. It was a pretty intensive day (out for 12-13 hours) for only a little bit of fossils but I thought some people might like to see the usual trip report photos and fossils I did find. Extensive clayey shale exposures are always worth photographing. Some horses were curious what I was up to but eventually lost interest. I'm not 100% sure this is Fox Hills (the clayey shale exposures of the Trail City and Timber Lake members look a lot like Pierre Shale when not accompanied by sandstone) but it didn't produce so it
  13. Despite the shortest and most mild winter I've experienced in North Dakota (getting out this early is rare) it still feels like it has been an eternity since I got out. Thankfully I finally got a hold of enough landowners to warrant a trip to the Fox Hills Formation and celebrate the spring weather. While most of the later sites I visited were a bust the first site of the morning was excellent and contained fauna not often found in the Fox Hills Formation in North Dakota. 3 new species for me in fact. This site represents a brackish transition area of the top of the Fox Hills Forma
  14. I've been posting Fox Hills Formation fossils from a recent trip but I feel that those are a poor representation of the often spectacular preservation and diversity of the Fox Hills Formation. Because of that I've decided to post some of my better Fox Hills specimens from North Dakota. We'll start with some lovely ammonites. Jeletzkytes nebrascensis is common throughout the Fox Hills Formation in the Timber Lake Member (perhaps a bit less so in North Dakota) and is a typical flagship species for the formation. This microconch from Emmons County is the largest complete J. nebrascens

    Fossil Hunting around Bismarck ND

    I have some relatives in Bismarck, North Dakota, and would like to know about fossil hunting opportunities in the surrounding area (preferably in a one hour radius of the city.) I already know about the Geological Survey digs, but would prefer hunting where you can keep what you find (or even just the common stuff.) Are there any pay to dig/ public access sites near Bismarck?

    Hell Creek Bird Bone?

    Another small Hell Creek bone found in North Dakota, this time it appears to be a the end of a limb from what I believe may be a bird, small non-avian theropod or perhaps even pterosaur. It has very thin walls which is what made me think that way and I would appreciate any input from my fellow members. The bone is about 1 cm in length and 6 mm at it's widest point at the bulbous base.

    Hell Creek Small Digit

    I found this tiny, slender bone at a Hell Creek microsite during my trip to the Dakotas in 2019 with PaleoProspectors. I'm not sure what it came from, but I'm hoping it's theropod, avian or otherwise. It's missing a section of the outer layer of bone and I believe the interior is hollow & filled in with the ironstone common in the formation. The dimensions are 1.7 cm in length and about 3 mm in width. I would appreciate any feedback you may have. In situ shot from the site: The closeup shots did not come out exactly how I wanted them lighting and detail wise. If you would l

    Another Tiny Hell Creek Toe

    Another tiny toe found in a North Dakota Hell Creek microsite, this little digit is 1 cm in length and about 5 mm in width. I know it's difficult to identify isolated digits but I was hoping we could potentially narrow it down to a general ID, turtle, croc, champ or other.

    Hell Creek Capering Tips

    Hello Fossil Forum members, this year my family wen t hunting in the Hell Creek Formation and we came back with some interesting finds. We even came back with an Edmontosaurus annectens metacarpal. This bone would have been from the fourth finger ad the first digit of the finger. Along with this very complete metacarpal, we found many more fragmentary bones and lots of petrified wood. Some of the bone fragments show very distinct features like length and one being very porous (suggesting that it might be a raptor bone). This of course is fun news as always to know you have officially hunted fo
  21. Paleocene plants in Central North Dakota are among the first fossils I've collected. Despite this I haven't given them the attention they are due lately. The preservation is very nice but due to various reasons they've taken a back seat to other outcrops in the state like the Cretaceous ones and I haven't thought about them for awhile. I am now reorganizing some of my Paleocene collection and a spark was reignited in me. I've decided to post some of the best examples here as a result. Come spring hopefully I can collect in additional Fort Union sites. The terrestrial Paleocene depo

    North Dakota Pierre Shale Trip

    I have an ambivalent relationship with the Pierre Shale. I try and try to find good sites that produce fossils but the end result is usually a fossil-less site. For a long time I quit trying exposures of Pierre Shale even though it's the closest fossil bearing exposure to where I live. About a year ago I decided to try the Pierre Shale again because it was close and I was too tired to go elsewhere, like the Fox Hills Formation in Central ND. Mostly I found worn Inoceramus fragments but to my surprise I found a nicely preserved caudal vertebrae from a mosasaur among float material. Following th
  23. Hi everyone, I haven't posted an ID in a while as I'm at college and don't have ready access to my fossils to take pics. However tonight, through sheer coincidence, I noticed a recognizable fossil online after looking at the new discovery of an albanerpetonid amphibian preserved in amber. After checking if these amphibians had been found in the Hell Creek I see an image come up of a jaw identified as belonging to scapherpeton (a true salamander) and recognized some features similar to a specimen of my own which I had never posted. I found this small jaw section in the Hell Creek fm. of North D
  24. I was very happy to see that recent publication that finally described the youngest known alvarezsurid Trierarchuncus prairiensis from the Hell Creek Formation. Material is rare but is most commonly overlooked and described as Croc or unknown theropod so knowing what to look for helps. I'm constantly on the lookout for this material and have been for years and have been fortunate to either find it or be able to acquire it over time. I used publications of other Alvarezsauridae like the Asian Mononykus and Canadian Albertonykus to help in the identification of my specimens.

    buffalo teeth

    I came across these in central North Dakota while looking for Teredo wood I assume they are modern buffalo teeth, but when I took a blowtorch to the root, it didn't have much of a burn smell. some of the small bits of root eventually blackened. This isn't so much an identification problem as a question- but confirmation of buffalo is fine, and if I am wrong, correction to the correct animal is welcome. Question: in the process of "fossilization", as collagen or whatever is replaced by minerals, how can you age a specimen, modern vs 'fossil' vs partially 'f
