Hello, I am making a great of in-situ pictures of my fossil hunting trips for this year. We now have a foot of snow in the ground so fossil hunting season is over. ☹️ These pictures occur in Wyoming, Montana, South Dakota and North Dakota. Mostly Cretaceous aged sites but some Eocene from ND. They are mostly tooth related. I hope everyone likes in-situ pics as much as I do!

New BBC Dinosaur Wildlife Documentary
Oxytropidoceras replied to Neanderthal Shaman's topic in Fossil News
Tanis: Fossil of dinosaur killed in asteroid strike found, scientists claim Jonathan Amos, BBC News, April 6, 2022 Scientists find fossil from THE DAY the dinosaurs died 66m years ago: Leg of Thescelosaurus was 'ripped off in aftermath' of huge asteroid strike that wiped out most species on Earth, The Daily Mail, April 7, 2022 Among the caims made is: "Experts found the fossilised leg of a dinosaur killed and what appears to be a fragment of the asteroid itself" Yours, Paul H. -
Palaeocarpinus sp. plant with seeds?
Mochaccino posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I'm looking at the following three listings for plant fossils, specifically Palaeocarpinus sp. "reproductive structures" with seeds. These are all said to be Paleocene age from the Sentinel Butte formation, North Dakota, and are all 70-100mm wide slabs. 1. 2. 3. I'm specifically wondering 1. if any of these seem enhanced, as I've heard sometimes is done with white shoe polish, and 2. whether they all seem to be the same species? For some reason the first two listings seem a bit different -
I have 2 small selections of shark teeth that I recently acquired in a collection that I had purchased. These teeth are supposed to have been collected in North Dakota and South Dakota. The first selection was collected on 4-3-1986 in Moffit, North Dakota in the Cannonball Formation, which was referenced by the collector as being Paleocene (58 MYO). The next selection was collected in Edgemont, South Dakota from the Late Cretaceous, Green Horn Formation. Any help on th

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

I found this bone on a fossil hunting trip in North Dakota, it was identified as a theropod, probably a T. Rex. Can anyone verify this claim? Thanks for any responces! (The ruler is mesuring in centimeters)

I am looking for help on some pelecypods that I recently acquired. The Id states that they are Paleocene in age and from the Tongue River Formation of Riverdale, North Dakota.

We found this while along the Missouri river in Bismarck North Dakota. The river is extremely low and we were aways out where the waters are normally deep.

The Hell Creek of North Dakota; a Chunkosaur or More?
Thomas.Dodson posted a topic in Fossil Hunting Trips
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- 7 replies

More Cannonball and Fox Hills Formation (An Unusual Ammonite) 8/9/21
Thomas.Dodson posted a topic in Fossil Hunting Trips
I lined up a couple more properties over the weekend so I made another trip out to exposures of the Cannonball Formation (Paleocene) and Fox Hills Formation (Upper Cretaceous). I only planned for two properties but the first was so large (an entire section with many outcrops) that I figured this was fine. It was a nice morning and much of the haze from the Canadian wildfires has subsided. Junipers often creeped over sandstone concretions on the cliffs. A slump exposure of Cannonball Formation viewed from the top of another exposure. The top of hills- 7 replies

Cannonball Formation Excursions 7/14/2021 (For Gastropod lovers)
Thomas.Dodson posted a topic in Fossil Hunting Trips
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- 6 replies

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.

Another Trip to the Cannonball Formation (sharks, fish, and crabs)
Thomas.Dodson posted a topic in Fossil Hunting Trips
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.- 8 replies

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

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".

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

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

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

Ammonite sites in Montana, Wyoming, North & South Dakota!
PrehistoricWonders posted a topic in Questions & Answers
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.
