This two Edmontosaurus metatarsals are for sale from a seller I trust however they were unable to tell me which digit of the foot that these come from. Would anybody be able to actually tell the digit from the ? @Troodon

I ended up buying this piece, and probably should have posted it here before i did that.. but here are two fossils listed as Ankylosaurus skull piece and scute. Can anyone here give their opinion on it? I don't have county, but it's from the hell creek formation, south Dakota. The largest piece is 10 cm long. @Troodon

Hi, I was recently at a gem, mineral and fossil show where I purchased this fossil that was labeled "Struthiomimus Claw". Upon a closer look when I got home something just seems off. It doesnt really look too much like a claw to me. The tag says that it is from the Hell Creek of South Dakota although that is as specific as it got. Does this look like a Struthiomimus claw? If not, is there any idea as to what it may be instead? Fossil is 1 inch long and and about .75 of an inch tall.

This has the size and J-shape cross section of a dromie premax. It also has the protruding mesial carina that you can see from a distal view. What do you think? Hell creek formation, Carter co, Montana CH: 15.6mm CBL: 6.7mm CBW: 4.7mm Mesial serration density: 6.5/mm Distal serration density: 3.5/mm

Would love to hear what do you think of this one? Hell creek formation, Carter co, Montana CH: 11mm CBL: 5.8mm CBW: 2.6mm Mesial serration density: about 5.3/mm Distal serration density: about 4.3/mm Thanks!

I have this tooth that I got from Tooth Draw Quarry. It's probably nano, but just wanted to make sure. CH is 15mm CBL is 8 mm. Serration density is about 4/mm distal and maybe 5 mesial. Sorry for the blurriness. Also, the base is only pinched on one side. Thanks for any help.

Hi, Looks like Rex to me. Hell creek formation, Powder River co, Montana CH: 22mm CBL: 11.1mm CBW: 6.3mm Mesial serration density: 15/5mm Distal serration density: 14/5mm

Hi, What do you think? Hell creek formation, Harding Co, South Dakota CH: 13.4mm CBL: 7.3mm CBW: 3.0mm Mesial serration density: about 5.5/mm Distal serration density: about 4.4/mm

Hi, Not sure this is identifiable. Rex? Possible huge raptor indet? Hell creek formation, Garfield co, Montana CH: about 27mm CBL: 11.1mm CBW: 6.2mm Mesial serration density: about 3.4/mm Distal serration density: about 2.6/mm

Hi, What do you think? Hell creek formation, Powder River co, Montana CH: 11.2mm CBL: 5.9mm CBW: 2.9mm Mesial serration density: about 7/mm Distal serration density: about 4.3/mm Thanks!

Hello, saw a few interesting things for sale. The first one is claimed to be a partial Tyrannosaurus rex skull from hell creek formation, locality is in image measures 12 cm-10.5 other 2 are both claimed to be partial limb fragments though I have doubts it can be narrowed to be from Tyrannosaurus rex. One is 2 and a half inch the other is 2 inch. I know that they say hell creek formation Wyoming which is weird. However I think some of hell creek form is in Wyoming? I would appreciate any help in verifying whether the items are identified correctly and if not what they should be described as.

I recently had the opportunity to purchase some jacketed fossils from a ranch in Garfield County, Montana in the hell creek formation. I bought 2 jackets, one with several small ribs present that I am currently working on. Another containing a single bone that I think is a hadrosaur pubis. One thing that surprised me was the wealth of smaller bits of bone present in the jacket I'm sure this is an amazing microsite I would love to see first hand. There were some really small bones that I don't think are identifiable but regardless very cool. This one with a really interesting convavity so maybe a joint in a small vertebrate? I also found what I think to be a ceratopsian spitter? It's very worn but it looks like some I've seen on the forum. And then another possible tooth? That unfortunately I was heavy handed in brushing off some sand before I consolidated it and it shattered. I also found what I think to be tiny petrified twigs, as well as what I think to be a piece of turtle shell that looks like trionychida to me but I'll know better when I get it cleaned off. There was also these pieces that vaguely resemble some carpals I've seen but are incredibly worn and not fully cleaned off yet. There were other various bits of bone as well that are waiting to be cleaned on my messy tray as well as a piece of coprolite? That I need to look at closer with a microscope. I got to the back side of the ribs without too much effort and that is where things started to get difficult, while I would love an ARO I'm fresh out of college and can't justify the purchase of that and an air compressor to my wife haha. So I am working with dental picks and some sculpting tools from my ceramics hobby. And a magnifying visor from yoctosun that I quite enjoy using with my glasses. The ribs were very generously coated in glue to stabilize them and about 2cm of matrix in any direction so I've slowly but surely picking off the sediment and softening it with brushed on acetone. I still have a long way to go before I even start the pubis and suspect that to get them where I wanted I might have to wait until I have a better set up to get some of the really stubborn bits off. The rancher thought they might be pachycephalosaur ribs which is possible, I know that ribs are tricky to ID. I have been having a hard time finding articles that describe hell creek ribs, let alone some that have pictures. It doesn't help that they aren't complete either so I am not comfortable assigning a species to them yet. I am very excited to start working on the pubis it will probably take awhile but my wife is leaving on clinical rotations, so I'll be alone for 6 months leaving me ample opportunity to prep after work. Thanks for reading, if you have any suggestions I would love to hear them.

Hi all, saw this listing for a tooth, it’s from Meade County, South Dakota and looks to me like either a Nanotyrannus or Tyrannosaurus rex tooth. Want your opinions, I personally am leaning towards Nanotyrannus due to the pinch however it seems to be pretty robust. Thanks in advance measures about 1 cm

A little slow in getting around to posting. 2 weeks ago my son and I got back from our yearly trip up north for fossil hunting. Like most years, we haul the tenement on wheels with us to save the crazy costs of hotel stays. We started out for the first 4 days in the Hell creek, digging with Walter Stein of PaleoAdventures. The first day was a little slow with lots of small tumbled bone bits and spitter teeth. Only bigger find was an unknown that I began to uncover, but didnt complete that day. The second day we changed where we were excavating and I found the first tooth of the trip. I found a great pinecone, the second ever, and 13 years since our last. A beautiful Nanotyrannus (our biggest ever by a hair). It had some acid etching and gypsum fouling, but would prep out well. 3rd day we went back to the first spot where I finished uncovered my unknown which turned into an unknown long bone next to a Thescelosaurus left ilium. The ironstone rocks it was bound in were crazy so it took me all day to finish exposing the surface. Day 4 was back at the ilium and clearing above it so I could pedestal and put on a plaster jacket. In the process of clearing, I uncovered an croc lower left jaw with a single tooth still in place. So then day 4 was spent finishing the ilium pedestal and pedestaling the jaw. The ironstone made the work slow, but I did pop out a beautiful (and huge) mammal tooth in the process! Walter said it may be the largest mammal tooth from the HC thats he's seen. We had originally planned to head over the fish quarries of Kemmerer WY, but we decided to stay and explore the Pierre shale and museums for a few days and then dig with Walter a couple more days. We went to the Belle Fourche reservoir (actually the Carlisle shale, not the Pierre) to look for ammonites and shark teeth. We did manage to find a few partials and one possibly complete ammonite, but we struck out in the search for teeth. After that we started to do some map recon of govt lands in the Pierre formation and driving back roads to find an area we wanted to try. I had little hope of being success in such a blind hunt, but we hit a motherload site I named "baculites heaven". They were everywhere. it was difficult not to walk on them in some spots. We filled 2 cardboard boxes with what we could carry and left super happy! Also found a set of deer antler sheds as a bonus. Now, last year we hunted a site on the invitation of Neil Larson. It a fairly well known site among many, and universities make trips to collect baculites there. The spot we found was every bit as good as Neils site, except we couldnt drive directly to it, and it required a bit of steep terrain hiking. The next 2 days were spent museum hopping. We visited the Mammoth dig site museum, the "world fossil find finder" museum (both in Hot Springs) and then the Black Hills Institute in Hill City. Day five in the Hell creek was back to the ilium and jaw. We started the day by jacketing and flipping the fossils, which was still a task with all the ironstone, but we finally got them out. Right after that, my son began excavating below where everyone else had worked. Basically below where all previous diggers had been sitting. Within minutes he popped out (literally it popped up!) was the best T.rex tooth (and only 3rd) we've ever recovered. A gorgeous 1.5 inch pre-max. Amazing that among all that ironstone, where people had been walking and sitting, and coming free with an ironstone rock removed, it was in perfect shape and not broken or even cracked. Our last day was lots of BOBs, chunks of turtle shell and more spitter teeth. Although not our find, I had to share this wonderful, complete Trike rib recovered. over the last couple years, more and more elements of a very large triceratops have been recovered, which is looking to be parts of a disarticulated animal. I don't have pics, but it also seems as if a disarticulated T.rex is also present. about 8 years the first femur of a rex was found while exploring, and now in the same location, more rex elements have been becoming uncovered, the last being a second femur. So, another trip is in our history book, with lots of great new fossils found. As a side note, a few years ago my son found a mammal jaw which was later sent to the Burke museum for study. This new mammal tooth uncovered is hopefully going to be part of the same collection, although Denver would probably like to have it too. A Pachy skull hornlet my son found last year, has a new home in the Melbourne museum. When I find out where any other element find a home, I'll update.

Hello I was looking at a few teeth and wanted help with identifcation First one I’m almost certain is a tyrannosaurid, even though it’s in horrible condition and am leaning towards Tyrannosaurus Rex due to robustness and no pinch. it comes from Garfield county, hell creek form and measures .6 inch. Second one is also likely a tyrannosaurid, im leaning towards Nanotyrannus but it’s probably a indeterminate tyrannosaurid. It’s from hell creek form, no locality unfortunately. Size is about 1 3/8 by 1/2 inch. 3rd one seems to be a Acheroraptor, also no locality besides hell creek form. And measures .35 inch. Last one is probably just indeterminate theropod tooth, maybe can be narrowed to tyrannosaurid? It seems to be a premax and also no locality besides hell creek, measures about .5 inch. Thanks in advance for your opinions.

Hi! I bought this piece a few months ago and just wanted to make sure it is what they tell me it is. Apparently it's a Triceratops horridus vertebra pedicle from the Hell Creek Formation of Dawson County, Montana.

This small tooth was found in powder county, it measures a little over half a inch and I wanted help with identification . Seller listed as either Nanotyrannus or Tyrannosaurus rex. I also think it’s most likely tyrannosaurid, and I wanted to know whether it’s tyrannosaurid and if it is whether it’s more likely to be Nanotyrannus or Tyrannosaurus rex. Im assuming it’s just a indeterminate tyrannosaurid because of the base damage and size, but please let me know you opinions.

Hey all, Any thoughts on this 2" (exactly) bone from Hell Creek, SD? Happy to provide better pics or other measurements if it helps. Thank you!!

A guy I traded with gave me this possible dinosaur claw. I'm trying determine if it's a dinosaur claw. He said he was snorkeling in hell creek and found it. It's about 5 inches give or take. It's heavy and It has a blood groove on one side which only dinosaur claws have and the other has grooves or grains of bone like look and feel. It resembles a dinosaur claw and the patina on it, brown like, would be the result of being underwater for a long time. Please some help here determining this is a dinosaur claw or something else. Thanks. Brittan

Good day. Recently got this mystery specimen from the owners of an extremely productive and well-known ranch in Powder River Country, Montana (please see photos). The specimen was found by the owner. Unfortunately, this specimen is not like those. Here's the only additional info: "This large piece of skull [?] was found in one piece. Weighs approximately 4 lb. 3 oz. The measurements are L 7 2/10" W 4 3/4" No repairs. Color is various shades of brown. Some of the openings actually have some matrix in them, but I left that, in order to stabilize the thin walls." I know it's particularly hard to ID a piece like this from photos, but if you have any ideas, I'd deeply appreciate them!

Hi folks, Anyone have any bright ideas on what this is and what species it might be from? 8 inch limb bone(?) fragment. According to the seller it's from the Montana portion of the Hell Creek formation. Both ends appear broken off, but I'm not sure if the bone features on the inside of the curve can help with ID at all?

I think this one is a little trickier than normal. Would love to hear your thoughts! The hell creek formation, Powder River County, Montana CH: 12.5mm (small adjustment for tip wear) CBL: 6.8mm CBW: 3.6mm Mesial serration density: 25/5mm Distal serration density: 20/5mm Complication: The mesial carina is straight as an arrow, but highly offset. Appears to maintain furthest distance from distal carina. Anterior tooth I suspect. Complication: There's a significant amount of root and uneven cracking to grapple with in base cross-section
