Hi, Any thoughts on this tooth? It is listed as a Nanotyrannus tooth, from Hell Creek Formation, Powder River County, Montana, USA. 0.78 inch. It's labelled as Nano, but the base is quite round--isn't that a sign of Rex? Any thoughts are appreciated. Thanks

Hi all. Wanted to post this tooth I got a while back for opinions. Seems quite a bit chunkier than the other nano's I have so figured it never hurts to verify. Tried following @Troodon's great guide but still new to this. Tip is cracked off so hard to tell exactly how big it was. Looking at the bottom view you can see a slight pinch on one side forming but you can't feel one on the other side when touching it. Feels flat. Hell Creek Garfield County, MT CBL 18.44 CBW 10.53 CH 33.19 (based on broken tip length) CH/CBL Ratio 1.79 Denticles @ 5mm Distal 14 Mesial 15

Hello- Some years ago I've bought this dinosaur tooth, labeled as theropod tooth; it comes from Carter County, South Dakota (Hell Creek Formation)- Its lenght is roughly 0,95" . I think it could be a tooth of a Nanotyrannus (or a juvenile Tyrannosaurus?), but I'd like to know the opinion of some expert about that- Many thanks in advance, Fabio

Identification Tyrannosaur teeth have similarly-sized serrations on each edge, and the serrations are chisel-shaped. This is a classic "Nano-morph" tooth being compressed and blade-like (which is the primitive condition of Tyrannosaurs). Notes This tooth has excellent preservation, with serrations crossing the tip, and clear enamel. There is a minor wear facet near the tip on the lingual side, indicating this is from the left maxilla.

Is this A Tyrannosaurus Rex or a Nanotyrannus tooth? Here's what I know: 0.75" (1.9 cm) Hell Creek Formation of Bowman County Nouth Dakota. @Troodon

Hi all. I'd like to begin by thanking the members of this forum for the profound wealth of knowledge that you all have shared with me during my search for further understanding of dinosaurs, fossil collecting, and fossils in general. Prior to joining, I was a longtime lurker that regularly referenced this forum and its many posts to answer countless questions that I had, and I continue to reference it! The information contained on this site is invaluable. I would especially like to thank @Troodon for his amazing guides and detailed write-ups, such as the case made for Nanotyrannus. That really settled the debate for me and convinced me that Nanotyrannus is indeed a separate genus. So thank you all! Now, with that out of the way, I'll get to the point of this post. I recently got my feet wet in this hobby and did what I'm sure MANY beginners have done before me. I began by acquiring a fossil of the most well-known dinosaur, and my personal favorite, Tyrannosaurus Rex. Specifically what was advertised as a partial T-Rex tooth. I can't afford a complete tooth at the moment, so I settled for the next best thing. Based on everything I've learned so far regarding T-Rex teeth and how to ID them, its characteristics seem to lean towards being a Rex tooth, but I'm by no means an expert on the subject, so I'd like to call on the many members of this forum that have more experience than I do and ask if they would be so kind as to share their opinions based on the photos and information provided. So as for the tooth's information. It's a partial tooth that measures 1.38 inches long, and the seller stated that it was discovered in the Hell Creek Formation of Powder River County, Montana. It does seem quite robust, and its shape and relative size seem consistent with Rex teeth. It also has a pretty round cross section. The serrations also seem to be pretty in line with Rex teeth, but I don't know if they provide any clear differential to typical Nano serrations. Photos taken by both the seller and myself have been attached. Thanks in advance for any help/opinions provided!

So recently my father bought a 3D printer and we've been experimenting printing some cool fossils for a while now. It's a really cool technology. Though it can take a while to print a piece the results are really quite cool. A life size Archaeopteryx can take a few days to print if you don't keep printing during the night. Finishing up the prints afterwards can also take a bit of time. Cleaning off all the supports and sanding down rough surfaces can be quite the process. Then there's painting depending on the desired result of course. There are actually a lot of nice things that can be found for download on the internet. Though many of these models still require a bit of digital cleanup before they could be printed. So here are a number of the painted, unpainted and half painted results. Most of the printed stuff is dinosaur. Photo of the 3D printer and the just finished print of a juvenile Edmontosaurus lower jaw. And here's the same Edmontosaurus jaw print half painted again with the real fossil in mirror image next to it. I scanned the original bone that I then mirrored digitaly so that I could print out the other side of the jaw. Allosaurus hand claw. Clidastes Mosasaur quadrate bone. Skull of the "Prosauropod" Massospondylus. Holotype right lower jaw of Owenodon hoggi, an Iguanodontid.

Hi everyone, would like to ask what you guys think of this labelled “Nanotyrannus Foot Claw”? Never really seen Nanotyrannus claws on the market so have no idea how to distinguish between other tyrannosaurs. And does the coat/ layer also look too thick? Almost looks like varnish? Unless its just their lighting that makes it too glossy. Thanks guys

I am a university student studying T. rex, so of course, I ran into the Nanotyrannus debate. People have been arguing about Nanotyrannus being valid, but there's a huge problem: No adult specimen. Unless someone has an adult, or even a subadult, specimen of Nanotyrannus (over 15 years old), it isn't a real genus. This is why I am here. I know people collect fossils and post pics of them on here, so I'm willing to see what people may, or may not, have. My question is: Does anybody have an adult Nanotyrannus specimen? In simpler terms, does anybody have a Nanotyrannus femur larger than 70 cm ("Jane's" and "Petey's" are over 70 cm)? Or a tibia about 90 cm or larger ("Jane's" and "Petey's" are 80-something cm, from what I've seen)? A fibula would work too. I'm willing to give the pro-Nano side a chance here. I'm in contact with a couple of paleontologists, some on the pro-Nano side and some on the anti-Nano side, and if anybody has any hind limb bones of a supposed Nano, then may I please see a pic of it? This is the only way you can prove that Nano exists. Teeth and hand claws will not cut it. As far as I'm concerned, all Nano teeth and hand claws are juvenile T. rex teeth, and T. rex claws. I'm asking for hindlimb bones only. Skull bones would do fine as well. Try to prove that tooth loss does not occur in T. rex ontogeny by providing pics of a maxilla or dentary. NO teeth, only a dentary or a maxilla. I'm not expecting anybody to give me anything of substance, but I wanted to give this a shot to see if I would be proven wrong. I'm being harsh because, if Nano exists, then there should be an adult specimen. All specimens are juveniles, no questions asked. Therefore, the genus does not exist. The only adult specimens of any tyrannosaurid that coexisted with Nano is T. rex, therefore Nano is a juvenile. It's just that simple. Prove me wrong though. Let me reiterate: Pics of femurs, tibias (even fibulas), maxillas, and dentaries, are what I'm after. If we can get a cross-section of a Nano femur, or tibia, and get an age estimate of 17 or older, or has extensive Haversian remodeling, then I'll believe that the genus exists, along with the majority of other paleontologists. Let's see how this goes!

Montana State Museum of the Rockies - July 2021
AlexSciChannel posted a topic in A Trip to the Museum
So over the past few days I was visiting Bozeman from Raleigh North Carolina as I was visiting the MSU campus because I've been accepted to start as a freshman in autumn 2021. And I hope you know what I am trying to major in. I mean you know what forum we're on I don't have to spell it out. Anyway, in that time I managed to spend all day visiting the Museum of the Rockies which is considered one of the Mecca halls for paleontology. Our crazy old boi Jack used to be Prof and curator there before... well you know. My home museum, the NC Museum of Natural Sciences are taxonomic lumpers when it comes to paleontology but they are passive lumpers. They are nothing compared to what the MOR has going on holy snarge I was surprised. I like going to different museums like this because it shows different perspectives based on findings that vary by institution. While I don't agree with a lot of it, it's healthy to expose oneself to different ideas and conclusions. Also I just couldn't help but feel giddy in the midst of all these dinosaurs. I'll update this post with pictures in a few moments... I will also post what the info cards on the exhibits state about each specimen. Here is Big Mike. A metal replica of MOR 555 commonly known as the Wankel although now more known as the Nation's T. rex since the og skeleton's move to the Smithsonian. I spent at least 30 minutes admiring the sculpt of this beautiful beast alone. Our first is a tibia of a Hadrosaur indet. found in 80 mya rock in Chotaeu, Montana so likely the Two Medicine Formation however this is unique because this is from it's lower strata which we don't know much about that's why it isn't identified as Maiasaura, as that dinosaur lived later. Here are some nice trace fossils and geology stuff, Here's the Precambrian globe Here's how sediments move through time. There's dioramas too. Starting with the Cambrian of course with Anomalocaris and working our way up. Here we're getting some Ordivician and Silurian description, Devonian like creatures. Although Coelocanths first evolved 400 mya they live all the way up to the present day. Stethocanthus below Next we start going in depth into the dinosaurs more updates coming stay tuned...

Hi all, I could not resist and took another shot on my quest to obtain a Dakotaraptor tooth. Here the tooth in question this time: It was found in the Hell Creek Formation, Garfield County. Measurements are: CH 1,41 cm - CBL 0,68 cm - CBW 0,3 cm - denticles per 5mm are 22 mesial and 19 distal. Note the slight tilt of the denticles towards the tip of the tooth. It's the best fit I have found so far, what deviates from the dePalma description is the shape of the base, it has a pinch, but I would not consider it rectangular. As a side note, it looks exactly like the base of Acheroraptor teeth I have in my collection. But, I am not an expert Thanks for taking a look!

Juvenile Tyrannosaurus rex tooth from Hell Creek?
TeethCollector posted a topic in Is It Real? How to Recognize Fossil Fabrications
I saw a Juvenile Tyrannosaurus rex tooth (or Nanotyrannus) with really good price.. Seller told that this is from Hell Creek formation, Garfield County, Montana. I can't find any oddity or fabrication... but I want to hear everyone's opinion since the price is too good to be true.

Two Tyrannosaurid teeth that I ordered early this week has arrived. This is the first tooth that I want to show, which is a tooth of a juvenile Tyrannosaurus rex (or Nanotyrannus). Since I personally believe that the Nanotyrannus is an invalid genus, I think this is a juvenile Tyrannosaurus rex tooth. For those who do not agree, this is a Nanotyrannus tooth. This tooth is from Hell Creek formation of Garfield Co. Montana. This is an 1-3/8 inch, and has some chips and scratches at the labial side, but I think this is still a great tooth.

Nanotyrannus teeth is real?
Josesaurus rex posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hola a todos. He estado viendo publicaciones durante mucho tiempo con dientes de nanotyrannus. Lo que me gustaría saber es si usted, que tiene más experiencia en la recolección de fósiles, podría identificarlos como pertenecientes a ese dinosaurio o no. De antemano muchas gracias. (Translated: Hello everyone. I've been looking at posts for a long time with nanotyrannus teeth. What I would like to know is whether you, who have more experience in collecting fossils, could identify them as belonging to that dinosaur or not. Beforehand thank you very much.)

Hi everyone! I have a large claw from the Hell Creek Formation of Harding County, South Dakota that I was hoping to have help identifying. It is large enough that I initially believed it stood a chance at being tyrannosaurid, but it seems a bit more compressed than tyrannosaur claws I’ve worked with in the past - particularly on the lower ridge. The ventral surface of the claw is also distinctly flat rather than rounded, which seems unusual. Could this be a Dakotaraptor claw or is that just wishful thinking? Large Anzu perhaps? It is right around 1.75 inches across the length of the claw (sorry, no metrics on this ruler). I have referred to the incredible guide posted by Troodon, and have some experience with various claws, but I still can’t quite come to a conclusion on this one. What are your thoughts? Thanks in advance!

From the album: Dinosaurs
Distal serrations of a juvenile Nanotyrannus lancensis (Hell Creek Fm., Dawson Co., MT). -
Hello! I got this tooth as a Christmas present, and to me it looks like a T.rex tooth, but the shape of the base made me less sure. I was hoping someone could help get a accurate id. The tooth is 10/16 of an inch long, and was found in Garfield county Montana.It has similar serrations on both sides, so I thought it was a tyrannosaur tooth. The shape, lack of pinching at the base, and thickness made me think it was T.rex, and the base looked to me like it could be a maxillary tooth since it was more rectangular than oval, but I wanted to see if anyone thought it looked more like a Nanotyrannus tooth. I can take any more pictures that would be helpful. Merry Christmas!

What's the deal with Nanotyrannus?
Thecosmilia Trichitoma posted a topic in General Fossil Discussion
What has been the outcome of the Nanotyrannus vs. juvenile T.rex debate? Is there now a definitive answer, or is it still a debated topic?
