Hello everyone, first post from me here. I have a 1.8 cm (roughly 0.71" for those who don't use the metric system) Hell Creek tyrannosaurid tooth that is in need of identification. Currently, the tooth is labeled as N. lancensis, though a while ago, the seller labeled the tooth as a juvie T. rex, and now I'm confused about whether I should label it as a Nano, a Rex or a Tyrannosauridae indet. (though since it's from HC it should be either of the first two) Notes: - Total serration count: 55 on both sides. - Pic 1, which consists of shots of the same tooth taken from all angles, was sent to me by the seller (the sketch in red was also his), which shows how the tooth is laterally compressed - quite interesting and not very T. rex-like, considering that even juvenile T. rex teeth are quite bulky. Moreover, the mesial carinae also ends quite high. Because of this, I had some doubts about his ID and would like a second opinion. TIA!

Hello. I saw this tooth available for sale labeled as a Juvenile T.Rex tooth. When I first saw it I was a bit skeptical on whether or not it was a juvie or a nano. Unfortunately I do not know the locality and I only know that it is 1.37 inches long and from the Hell creek fm. Thanks for any help!

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 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.

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. Tooth 2: I posted a similar tooth before awhile ago. It was also kind of a mystery. This one's a fair bit bigger though. I've heard rumblings of a "third Hell Creek Dromaeosaur" similar to this. Of course it could also be a Nanotyrannus. Tooth 3 and 4: These are really interesting. I initially thought they were Nanotyrannus, but much like the first tooth there is no trace of serrations on the mesial carina and it seems there also never was. Tooth 4 has some wear on some parts of the carina but other places are without wear and have no traces of serrations. Meanwhile tooth 3 has a great carinae and no traces of serrations. Another member showed me pics recently of Dromaeosaur teeth similar to this and I'm wondering if these are Dromaeosaur anteriors or I'm just imagining things and their little Nanotyrannuses. Any insight is greatly appreciated as always!- 2 replies

Hi everyone! Here's another little tooth that has me stumped. It has a pinch like a Nano, but the serration density is what I've come to expect from a raptor. At least I got some really nice shots of the serrations! CH: 8 mm CBL: 5.5 mm CBW: 2 mm mesial serration density: 6/mm distal serration density: 4.25/mm So what do you all think? Nano? Dakotaraptor? Tyrannosaur/Dromaeosaur indet.? Any insight is appreciated as always!

Hi there everyone! I've recently been adding specimens to my collection and I came across a listing advertising a juvenile tyrannosaur / nanotyrannus tooth coming from the Hell Creek formation in Montana. The seller is very reputable thus I have no doubt that the specimen itself is truly a fossil. Instead, I was wondering if anyone could help me positively identify the specimen as being from a juvenile tyrannosaur / nanotyrannus (depending on which camp you come from). Thank you!
