I have this tooth that i believe to be a small nanotyrannus but i just want to get confirmation so let me know what you think everyone. Its from the Hell Creek Formation. Garfield Ct. Montana. Its CH is 11 mm Serration count: Distal 12 per 3 mm Mesial 15 per 3 mm The base of this tooth is beat up so its impossible to see if it would have had that rectangular pinch that is characteristic of nano teeth. There seems to be no twist of the mesial carinae In my opinion the serrations look peg like as seen in nano teeth.

I messaged seller a week ago for extra photos and haven't heard anything back, unfortunately, so this is all there is. Sold as a Tyrannosaur vertebrae and Optical Condyle bone. Found in Baker, Montana. That's literally all the info there is--not even measurements, and there's been zero response from the seller unfortunately. So, sorry about that. If anyone can suss anything out from the dodgy photos, that would be great.

Juvenile T. rex maxillary tooth basal cross section

Tyrannosaurus rex Hell Creek Fm., Wibaux Co., MT, USA Minor compression, common in maxillary teeth. It closely matches my larger juvenile T. rex. -

Tyrannosaurus rex Hell Creek Fm., Wibaux Co., MT, USA This is a juvenile Tyrannosaurid tooth. The serration densities are similar on each carina, the serrations are chisel-shaped and robust, the tooth is not recurved, and the mesial carina is straight. It closely resembles my larger T. rex maxillary tooth in cross section. -

Hi y'all, got this small theropod in the mail; I bought it suspecting it was Tyrannosaurid. Upon in-hand inspection, I believe that suspicion is confirmed. It bears close resemblance to one of my larger juvenile T. rex maxillary teeth. It also appears to have a slight pathology near the apex - a slight bend. @Troodon Tyrannosauridae Hell Creek Fm., Wibaux Co., MT, USA CH: 9 mm Mesial serration density: ~ 5.3 / mm Distal serration density: ~ 5 / mm Serration densities: Serrations: Here the pathology is more evident: Base (comparison with other T. rex maxillary tooth, right):

Good morning buds! Managed to acquire for a very affordable price this theropod tooth, told from Judith River Formation. The seller believe it's Saurornitholestes langstoni, but some guys from my instagram account where I have posted it suggested it's a small tyrannosaurid. The only pic is missing is the base view, but the tooth base is almost rectangular. Very flat. Can't spot the denticle tips pointing up on mesial carina. If someone can tell out more from it it would be really appreciated! Thank for your time, have a nice day!

Hello all, I need some help ID'ing these two tyrannosaur teeth from the Two Medicine Formation in Montana. Does anyone know how to tell the difference between Gorgosaurus and Daspletosaurus teeth based on this size? Thanks for any help.

Hello! I'm a new member and I discovered this forum recently. I've already learned so much browsing threads. I'm not sure if it'll be possible, but I was hoping that I could get some help identifying a section of fossil scapula that I came across and was thinking of purchasing. The seller doesn't have much information on it besides it being a Hell Creek find in South Dakota. He thinks it may be from a tyrannosaur. Pictures attached, any thoughts would be great!

Hello, I noticed on some pictures on Teeth in the past and recent there are allot of scratch marks. I was wondering what they are ? Perhaps I silly question, but im just learning as i go. Are these from excavating ? or did the Dinosaur did this by biting during its live. (photo by Roby)

Hello, I am interested in this. Tyrannosaur from Judith River, Hill County. 2.5 cm. Seller says Gorgo or Daspleto (I guess it is impossible to tell which) but is it a Nanotyrannus instead? Because of the indents on the base. Tip is repaired, but any restoration? Thanks

This should be a Tyrranosaurus Rex Tooth. Correct? Info regarding the Tooth: Fossil information : Hell Creek Formation, Jordan, Montana, VS. Size: 58mm, Cretaceous (66 - 70 mil y) The tooth been left as found. Just some cleaning. Has a very nice natural wear on the tip. I have seen some other Tyrranosaur Rex tooth trough searching, they were much rounder and thicker towards the lower end. Perhaps those are located differently in the jaw more to the back to crush meat. Looking forward to your thoughts

What is the True Identity of the Phoebus Landing Tyrannosauroids?
AlexSciChannel posted a topic in General Fossil Discussion
What is the most likely attributable identity for the Tyrannosauroid remains at Phoebus Landing of the Tar Heel Formation? What I am referring to specifically are bones documented in Baird and Horner's 1979 paper which speaks of a distal third of a right femur that is attributed to cf. Dryptosaurus and is smaller than the holotype of D. aquilunguis. It is also compared with Albertosaurus which shows similarities as well but that's expected with Eutyrannosaurs. Also there is another distal left femur of a tyrannosauroid shown to be found in a Hypsibema bonebed and originally attributed to the Hadrosaur taxon as a tibia but later revealed to be part of the femur of Tyrannosauroide Keep in mind at the time they were attributed to tyrannosauridae until dryptosaurus was shown to be part of an outgroup from the main family. My only question is, are these specimens possibly referrable to Appalachiosaurus instead of Dryptosaurus? It could be possible as the time of description of these specimens Appachiosaurus was not described yet. There are a few flags that could make such bones the cf. Appalachiosaurus instead, like the more pronounced medial condyle than that of Dryptosaurus which is smaller and less noticeable. This I noticed with specimen ANSP 15330. Although it is overrall smaller than the Dryptosaurus holotype this could be just a sign of it being in a juvenile ontogenetic stage. And despite being smaller not only is it's medial condyle larger, the politeal pit and the intercondylar fossa are deeper and more prominent. Although I cannot say the same for the larger left femur Cope mistakenly thought was a Hypibema tibia. This femur is larger than the Dryptosaurus holotype however it's fossa and processes aren't as pronounced. Although this could be attributed to the fact it is largely abraded and weathered. Here is the subadult Appalachiosaurus right femur from the holotype (ignore the left tibia included below it);

Hello everyone, I hope im posting in the right topic section, if not please guide me Im looking at a Suchomimus Tooth for myself im a new collector. I found one that looks really cool , A bit Ivory-like patina. I found out that most of them are much darker. So my only fear was: is this a Suchomimus tooth or not? Please find some images of it bellow. The tooth measures 50mm (5cm or 1.96 inch) its found at Gadoufaoua, Téneré Desert, Niger Thanks for your guidance Best, Phos_01

Went on a wild fossil hunting trip today out on private land in the Dinosaur Park fm. and found something that I’ve since reported to the Tyrrell. My best guess is a partial hadrosaur tail. The specimen is about 3 feet long by 1.5 feet wide. There was no other associated material nearby but there may be more of this dinosaur under the surface. I’ll also post a few of my favourite surface finds for today. I have a before and after photo of a vert, a large partial rib and some tyrannosaur teeth & a croc tooth.
