I was going to wait until tomorrow night to post the 3rd tooth but i got around to taking some pictures and measurements now so here is Unidentified Theropod Tooth #3. Judith River Formation Hill County Montana Crown height 15 mm ( broken base ) Serration count 17 per 5 mm distal 20 per 5 mm mesial I do not see a twist in the mesial carina This tooth is more compressed than the other two teeth the first being dromaeosaurus. Saurornitholestes perhaps?? @Troodon

This is the second unidentified theropod tooth i just recently received. This tooth has a broken tip and its missing most of the mesial serrations. These are the measurements i observed followed by pictures for your own assessment. TOOTH 2 JUDITH RIVER FORMATION HILL COUNTY MT Crown height 12 mm ( missing tip ) Distal serrations are 3 per mm Mesial are 4 per mm There looks like there is a twist in the mesial carina Dromaeosaurus/Tyrannosaur?? @Troodon

Whats up everyone!? So i just received 3 new " Unidentified Theropod " teeth . I will be posting 1 a night for the next 3 nights. All of these teeth were found in the Judith River Formation in Hill County Montana. Heres Tooth #1 Judith River Formation Hill County MT CH 16.5 mm 14 serrations per 5 mm on the distal side of the tooth 17.5 serrations on the mesial side of the tooth Twist present on the mesial carina My thoughts - Dromaeosaurus Albertensis..... Tell me what you all think? @Troodon

Whats up all! I havnt posted in a while mainly due to just having everything all over the place since we've moved back into our house after a long time away due to renovation. I still have a ton of fossils in my collection and alot of unidentified teeth that im going to try and post on here more often.....ill be posting 2 tonight with the first being this tooth here : Its from the Hell Creek Formation, Tooth Draw Quarry , NE Butte County, South Dakota. Its CH is 13 mm The CBL is 8.5 mm Distal serration count is 3 / mm Mesial serration count is 4 / mm Base has an oval shape to it. Ill post a bunch of pics since some are better than others...anyway let me know what you all think ! @Troodon

This next tooth im posting is another one from the Hell Creek Formation. It was found in the Tooth Draw Quarry in Butte County South Dakota. Its CH is 14.5 mm CL is 5.5 mm Its got a round base I wish i could give you a serration count but there arent any so this may be a tough one. Paronychodon maybe? Give it your best guess! @Troodon

HC Tyrannosaurid tooth
andy_mnemonic posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone! I found this little tooth for sale and was wondering if it could be ID'd as a Nano or T-Rex. It is from the Hell Creek Fm, Garfield Co, MT and is 12mm x 8mm x 4mm. I thought it had the chance to be a T-Rex maxillary tooth since I don't see a pinch on the base and has a robust tip. Thanks for your input!

Here is my baby T-rex 3d print. 3d files came from https://cults3d.com/en/3d-model/various/life-size-baby-t-rex-skeleton-part-01-10. This one took me about 8 months to complete.

Hello everyone, On this edition of Rex or nano, we have this nice little mailbox score I got earlier this year. The seller and I are reasonably certain that it is a young adult rex. But I wanted to bring it to you folks to get your assessment. It matches the locality of Rex ( hell creek, from a microsite in Carter county) and based on my research from the forum and elsewhere it checks out as tyrannosaurid. (Ie: robustness and seemingly no pinch) Bonus question: I'm also curious on the placement of the tooth in the animals jaw. I have reason to believe it may be a right maxillary tooth.

Hi I have a question, I went back since I had some time and re measured my Tyrannosaur tooth denticles. But there both the same size, the Mesial and Distal are both 6. And the DSDI is 1, what would this mean? Thank you!! @Omnomosaurus, @Troodon

Hi I have a question would a whole tooth be better then a whole bunch of pieces of a tooth? I found some Tyrannosaur teeth and there was a whole tooth for a more expensive price and there was a whole bunch of tooth pieces for a lot cheaper then the full tooth. Which would be better for research purposes? Thank you!!

Hi I have a question, has there been anything on the Tumbler Ridge Tyrannosaur? And have they identified it in any way yet? Thank you!!

What species of Tyrannosaur did this tooth replica come from?
dinosaur man posted a topic in Fossil ID
Hi I found this with the rest of my fossil replicas and was wondering if it could be a Rex tooth or another type of Tyrannosaur tooth. I don’t know if I can post this here or get an ID on it since it’s a replica but I got it at the Royal Tyrell Museum in Drumheller, Canada it’s a replica of one of there specimens. And I just wanted to know what it could be since it seemed strange to me on how skinny and long it is, Thank you!!
-
This is a tooth I have purchased, and I was wondering if anyone had any idea on a species for this guy? The seller said it was from Uzbekistan, but the colors are very different from teeth I've seen from that area. Any input or information is greatly appreciated! The tooth is 2.75 inches long.

Hi, Since the group Daspletosaurini has just be established. Wouldn’t Nanuqsaurus be part of it, it is known as a Tyrannosaurinae but since the clade/group Daspletosaurini has been established wouldn’t it be a Daspletosaurini? Since it shares some features with the Daspletosaurini.

Next tooth up is a "unidentified theropod " tooth from the judith river formation in eastern MT....its CH 8 mm....it has 13 serrations per 3 mm on the posterior of the tooth and 16 per 3 mm on the anterior.......some of the pictures youll see what looks to be ribs on the side of the tooth, i thought zapsalis at first but i dont see the posterior as having a straight edge .....let me know what u all think after viewing the pics! @Troodon

Hey everyone i hope you all had a great holiday season....this next tooth in my collection was labled saurornitholestes from the hell creek formation from powder county MT. We know that the only two described raptors from there are dakotaraptor and acheroraptor so im curious to see what you all think of this one. Nanotyrannus perhaps? Unfortunately the anterior serrations have worn off which im sure will make id'ing this tooth difficult but anyway here it is. ....the CH is 9 mm the posterior serrations are 12 per 3 mm. @Troodon

Hi I decided to make a quick guide on how to ID Tyrannosaur teeth from the Belly River Group of Alberta, and the Judith River, Two Medicine Formations. I got this information on a study on how to ID isolated Tyrannosaur teeth from Dr. Angelica Torices. I’ll start off on saying Albertosaurus and Gorgosaurus are extremely alike not much differences in the morphology Daspletosaurus is a little bit Different, the morphology of these two Tyrannosaurs (Gorgosaurus and Daspletosaurus) are probably do to similar evolutionary history Gorgosaurus could of been Albertosaurus ancestor. Now I’ll tell you how to tell these two Tyrannosaur teeth apart (Gorgosaurus and Daspletosaurus). Gorgosaurus has two denticles (serrations) per mm where’s Daspletosaurus does not. Albertosaurus also have two denticles per mm because of Albertosaurus and Gorgosaurus evolutionary history. Also one more thing only with Albertosaurus, juvenile teeth can be different not just in there size but in there morphology too to the Adult teeth where’s Gorgosaurus and Daspletosaurus juvenile and adult teeth always have the same morphology. And thats what I’ve learned about this topic hope it helps, enjoy!!.

Hi can anyone tell me what happened, or why this Tyrannosaur tooth looks this way. It looks very odd to me Thank you! it’s from the Judith River formation of Montana, and is 1.2 cm.

A Walk Through Dinosaur Provincial Park, Alberta, Canada - 22/7/18
Paleoworld-101 posted a topic in Fossil Hunting Trips
This report is a bit late, but better late than never! During late July through to mid August 2018 i was on a research trip to study a new Canadian dinosaur footprint site for my Masters degree project. I am based in Australia, and this was the first time i had been to Canada! So of course i had to make the most of it and pay a visit to the world renowned Dinosaur Provincial Park in southern Alberta, arguably the richest site in the world for dinosaur fossils. The park is the best exposure of the Dinosaur Park Formation (which it is now named after), which dates to about 76.5 million years ago during the mid-Campanian. I had long read about this location and watched it on documentaries for so many years growing up as a kid. Finally being there in person was very surreal! I was quite lucky and managed to go on a long, extended walk through the park with one of the guides for about 6 hours in total. In this relatively short amount of time i observed so many amazing fossils. I must have been completely desensitised within the first 30 minutes! It really is incredible how much fossil material there is lying all over the park. In Australia, whole scientific papers are written about isolated or fragmentary dinosaur bones, yet here they were just lying everywhere! The pictures really speak for themselves. As said, all of these fossils were observed in the field during a single days visit to the park. As this is a World Heritage site, nothing was taken, all finds were put straight back onto the ground after i took these photos. It's a VERY hard thing to do, but rules are rules. The only thing that was removed from the park on my trip was my best find of the day... a near-perfect 5.3 cm tyrannosaur tooth from Gorgosaurus!!!! This find was too special to leave behind, so the park tour guide GPS marked the location and brought it back for display, likely at the visitor centre or as a demonstration piece for their guided tours. To say that i have found a tyrannosaur tooth is a great honour! You may remember it from the July 2018 VFOTM poll. Without further ado, here are the pics! It is going to take multiple posts to fit them all in, so scroll all the way down to see them all! Various dinosaur vertebrae. Everything from hadrosaurs (duck billed dinosaurs) and ceratopsians (horned dinosaurs) to theropods (two legged meat eaters) and ankylosaurs (armoured dinosaurs). These were so common! I would probably pick a new one up every 5 minutes or so. Ankylosaur tooth

Hi I recently found out that my new tyrannosaur species from my topic unknown Tyrannosaur happens to be a new species but not what I thought. It was already known to be a new species for a while. It turns out it's a Daspletosaurus sp., A unnamed Tyrannosaur that Currie recognized years ago to be a new species of Daspletosaurus from the Dinosaur park formation. Still not much research has been done on it. I decided to learn more on the Dinosaur park formation Daspletosaurus sp. But I can't find anything on it, no papers no information, other then a few mentions in some books and study's but that's it. I am wondering if anyone here can help me out with that? Thank you!!

I was reading some posts about tooth ID last night on the forum. I read that dromeosaur teeth from the Hell Creek formation have different serrations on the front and the back. If I remember correctly, I think I saw a post that said the back side of the tooth have larger serrations. I saw this tooth from Carter county Montana this morning, listed as dromeosaur but to me it looked like both sets of serrations were pretty uniform. I was wondering if there’s a chance this is a tyrannosaur tooth, or if it is some type of dromeosaur tooth. It’s approx. 3/8 long, so maybe the size alone is enough to rule out tyrannosaur but I thought I might as well check. Unfortunately only 2 pictures were given.
