Hi everyone! I recently acquired this from the Hell Creek of Carter County. I assumed it was a juvie Rex and but was asked to check the serration density and it came back weird so I thought I'd ask for some input. I'm hoping I can at least rule out Nano which I will be shocked if this even has the possibility of being Nano. We might be looking at another "Larsonraptor" situation (if you know you know). CH is 26 mm CBL is 11 mm CBW is 8.18 mm mesial serration density is 14 for 4 mm distal serration density is 10.5 for 4 mm DSDI is 4/3 Any insight i

Hi everyone! Another little gem I acquired recently, sold to me as Nano, figured it was Nano, now looking at it I'm wondering if it's indeterminate as the base is damaged so I can't see a pinch, and it's kinda thick. So what do you all think? Any insight is appreciated as always! CH is 3.06 cm CBL is 1.41 cm CBW is .786 cm (I also got a digital caliper finally) Powder River County Montana Hell Creek

Hi everyone! I recently acquired a very large (3.5+ inches) digested Rex from McCone County, Montana. The seller said no repair or restoration and I just wanted to make sure. I shined a UV light on it and there is one area that I'm interested in. Along the mesial Carinae is a very dull green under the UV. I tried to capture it with my phone but all I got was blue light since my Camera isn't equipped for that. Typically when I see restoration it's a very bright and vibrant green under UV so I'm not sure if this dull green area is restoration, if it's just an area that was stabilized, or if

I obtained this tooth on a dig back in early June close to Jordan, Montana and was immediately told it was definitely a raptor tooth and was content with that. But more recently I’ve gotten curious and done some reading to try to figure out what exactly it was. From what I’ve read and seen online, it is pretty much a token Acheroraptor tooth with the very apparent ridges and larger serrations on one side while the other has small or none, but I wanted to double check with someone more familiar with the teeth to make sure. I’ll post any pictures requested, thanks! (also, please don’t

Hi everyone! I acquired this Vertebra a few months ago. It's from the Hell Creek of Powder River County, Montana. The seller listed it as Theropod and I was hoping to make sure. It measures 3 cm long, 2.6 cm tall, and 3.2/3.5 cm wide on the centrums. So what do you all think? Any feedback is greatly appreciated as always!

Hi everyone! I recently acquired some little Therapod teeth from the Hell Creek of Carter County, Montana. They were advertised as "Dromaeosaurus" so I knew right away most were going to be little Nanos which I was fine with. I screened out the ones that were definite Nanos and was left with these three little mysteries. No ridge along the crown so Acheroraptor is out. the serration densities were a little unusual so I figured I post them to see if any might be Dakotaraptor or if I'm just seeing things. I posted a larger pic of the lingual twist of tooth one right under it since co

Hi everyone! I have my eye on a potential Rex but the seller isn't sure if it's a rex or a huge Nano. The measurements they gave are 1.75 x .6 x .37 Inches so about 4.46 x 1.52 x .94 cm. It's from powder River County Montana The tooth is an anterior and the oval shaped base combined with it being that large of an anterior says rex to me, but I figured I'd seek a second opinion.

Hi everyone! I have my eye on an interesting claw from Hell Creek in Carter County Montana on "that website" and was wondering if anyone could give some extra insight. The seller listed it as Alvarezsaurus, which I had honestly never heard of before, and a quick search revealed that genus is much older than Hell Creek and from South America. I think they might mean it's from the Alvarezsauridae family, but in any event before I try for it I figured I should ask for an outside opinion on what this is from since this group is new to me.

Hi there everyone! This one might be a bit of a tough one. I came across this listing for a possible partial ankylosaur osteoderm or pachycephalosaurus skull armor and was wondering if anyone could help positively ID the specimen. The fossil was found on private ranch land in Harding County, South Dakota. The specimen is small and obviously a fragment so I’m not expecting any clear answers; but in the past I have come across whole ankylosaur osteoderms that looked very similar in terms of texture and coloring, so my untrained eye is inclined to lean towards that conclus

Hi all, I saw this interesting specimen online. It is labeled as Ankylosaur dermal scute, was found in the Hell Creek Fm., Hill County, Montana. Size is 4,8 cm x 3,2 cm (1.88" x 1.26"). These are the pictures provided: What strikes me about this specimen is the shape of the bony base and the grained surface. My knowledge about osteoderms is rather limited, so I was wondering if anyone can support or refine the given ID? The only image I found so far that resembles that shape, as opposed to the flat sided scutes, is that of an thoracic osteoderm (https

Hi everyone! I acquired this vertebrae a little while ago. I'm reasonably certain it's dinosaur and and would greatly appreciate some help narrowing down the ID. It's from the Hell Creek Formation of Powder River County, Montana. The piece is 5 cm tall, 4.7 cm wide, and 2.9 cm long. The centrums are 4.2 x 3.6 cm and 4.4 x 3.7 cm. The bone is really spongy which is best seen in pic 2, the pores are all 1 to 2 mm so I'm kinda leaning toward Theropod (if that has nothing to do with a Theropod ID please correct me). So what do you all think? Any feedback is greatly app

Hi everyone! I acquired this in a batch of turtle claws from Hell Creek in Powder River County, Montana, and it stood out to me as a bit different looking. I'm wondering if it's something else like Crocodilian. Length is 29 mm, width is 11 mm, height is 9 mm. So what do you all think?

Hell Creek Theropod teeth id help Raptor? Troodontid? Nanotyrannus?
jikohr posted a topic in Fossil ID
Hi everyone! I recently acquired some really interesting little Theropod teeth from the Hell Creek Formation of Carter County Montana. I have my suspicions on IDs, but I would really like a second opinion. Tooth 1: My first thought with this little guy was Troodontid, but I have no experience with Troodontid teeth. It might also be a really tiny Dromaeosaur. No serrations or even a trace of serrations on the mesial side is kind of a unique feature. It doesn't look like they were there and wore off either, it looks like there were never serrations on that side. -
Hi everyone! I acquired these two pretty recently and immediately though Juvenile Rex, but after that other one I figured I should be more careful and ask for a second opinion. Both are from the Hell Creek of Powder River County, Montana. Tooth 1: Crown Height: 11 mm Crown Base Length: 5.5 mm Crown Base Width: 5 mm Mesial serration density: 4.5 per mm Distal serration density: 4 per mm Tooth 2: Crown Height: 14 mm Crown Base length: 7 mm Crown Base Width: 5 mm Mesial serration density: 4.5 per mm Distal serration density:

Hello, I’m thinking about buying this for my first dinosaur tooth. And I was just wondering if you guys think it’s a tyrannosaur rex or nanotyrannus tooth. It’s from hell creek formation.

Hello! I saw this 1.06 inch Tyrannosaur tooth from the hell creek formation in montana labled as a juvenile T.rex tooth. (he has other teeth labled as nano teeth so it wasn't his personal preference) I'm not good at telling them apart so that's why i brought it here! So is it a juvie T.rex or a nanotyrannus? Thank you!

Hi all Emmm, this is my first Tyrannosaurus tooth, yes, I had no experience at the time, but I still remember how excited I was when I got this tyrannosaurus tooth, even now. Yes, he was a broken tooth, and it was expensive.And now I want to know the tooth ID.I think it's nanotyrannus. All I know is it's from hell Creek, Montana, no county. Thanks

I have a nanotyrannus tooth( 2 1/8" inches )from the Hell Creek Formation of Montana. But now I have doubts about its authenticity ,Because I saw a fossilID topic that ultimately thought it was Dakotaraptor,I think mine is a bit similar,So is it a Dakotaraptor tooth or a Nanotyrannus tooth? Thanks!

Hi everyone! I just got a claw in from the Hell Creek and I'm not entirely sure what it's from. I know it's not dinosaur, but I don't know how to tell the difference between turtle, crocodilian, and Champsosaurus (what does a Champsosaurus claw look like anyway, google didn't have any pictures) or even something else if there is a something else I'm not aware of. Locality is Powder River County, Montana. Length is 36 mm height is 15 mm width is 13 mm Any insight would be greatly appreciated as always!

Hello, I recently bought this tiny bone fragment, a supposed piece of Tyrannosaurus rex vertebral process, from the Hell Creek Formation of Harding County, South Dakota of USA. I know nothing about ID'ing dino bones or bones in general. The seller's rationale for the ID was that the porous honeycomb structure is diagnostic of large theropods, with the only one in this formation being T. rex. Does the ID seem correct? Is this T. rex proper or is that impossible to determine? The piece is 3 cm long. I've propped it up to better visualize the large pores inside the fragmen

My youngest brother found this on his first microsite hunt. I could not believe it. I have not found many mammal teeth and am unsure as to what this belonged to. I also added some pictures of another tooth found in the area that I am having a hard time placing an ID on. Any help is appreciated! Hell Creek formation, Dawson County, MT.

Hello Eveyrbody! I have a question about Tyrannosaurus rex teeth. A recent study has shown that T.Rex accounted for about 24% of the creatures in the hell creek formation. T.Rex were more common then edmontosaurus. Yet it is usually the most expensive fossil you can get from the hell creek/lance creek. So if Edmontosaurus were less common then T.rex then how come their fossils are way cheaper?

Thanks for all the ID help lately. I've got another that's interesting to me, if you've got time. From the hell creek formation, Garfield Co, Montana CH: 12.1mm CBL: 4.6mm CBW: 3.0mm Mesial serration density: smooth, but curious to see if you perceive signs of worn denticles Distal serration density: about 4.33/mm Serration shape: tyrant or something else worn down?? Base cross-section: Oval--almost round Mesial carina: Hard to say if straight. Sort of seems straight but very offset from center.

Hello, I got this tooth that was labeled "raptor" from the hell creek fm. In the ad--and now in-person too--I think it's a T. Rex tooth. The trickiest part is getting anything on the mesial carina, there's quite a bit of wear / weak / lack of denticles. I'd love to get your thoughts on whether there's enough here to stamp it T. Rex. About 3/mm distal Attempts as mesial carina (strong twist)
