I have 2 campanian tyrannosaur fossils, one from the Judith river formation from Blaine county in Montana, and another where the only locality I know of is that’s from the two medicine formation. I was wondering if the locality can help determine between Gorgosaurus, Daspletosaurus and Albertosaurus, or if any formations are limited as to which species is present.

I bought this tooth a few moths ago, and I’ve been wondering if it was from the front of the mouth or not. It’s a tyrannosaur Indet tooth from the Judith river formation, and it’s about 1.25 inches long. It was listed as a front maxillary tooth, but I wasn’t sure if there are any other types of teeth besides the premax teeth the front teeth on the bottom (I think they’re called dentary teeth?)that have serrations on the sides of the tooth instead of the front and back.

Hello, It has been a little while since I've posted here; but I'd like some help if possible. I rarely buy fossils but as I'm a ceratopsian fan and we don't have any in our local formations (UK) I've decided to buy a tooth; I'd just like ID confirmation and wether it's a good example. I don't mind a little feeding wear nor matrix, which it has, but from what I've seen via search engines is that the preservation (Judith River Formation) and the fact that the tooth is rooted is quite good? I bought this from FossilEra and I assume they're still reputable. It's noted down as chasmosaurus sp. I reckon you can only ID down to a genus? I don't know much about the Judith River Formation; so it'd be nice if someone could help me out with some context. 1.55 inches long (photos are taken from the website, they're not my own) All the best!

This is a piece of fossilized bone I bought over the summer. It was sold as being from a centrosaurus. I understand that a perfect ID is impossible, but I was wondering if any one had an idea of what type of dinosaur it could be from, if it even is dinosaur. I was also hoping to find out what type of bone it is. It had an interesting shape to it so I was hoping if nothing else, where in the skeleton it could have been from. It says it’s from the Judith River formation, and the only locality given is eastern Montana. Again I don’t think it’s possible to tell exactly what it’s from, I was just hoping for some general description.

We did a lot more work on our shark stuff this summer than dinosaurs but we did change how display the non touch fossils. We added a few new items too but stayed light on additions. First up is our updated Cretaceous North Africa display. We added a really nice theropod tooth that fits @Troodon ‘s Morph Type 4 Dromaeosaurid-like profile hence the label for the program. We explain the ID difficulties of fossils so for a tooth like this they know we are not sure of what critter had this tooth. I am pretty happy with how this one looks. We give a nice picture of Cretaceous North Africa from two different times. This is an important part of our program and we have some nice fossils I think. We also have two touch fossils with this section. A limb bone that we go with Spino as the critter and one is a theropod very that we use to talk about Deltadromeus.

Hello everybody So this tooth here is up for sale. Described as a Daspletosaurus tooth from the Judith River Formation. (Not more information) Length: 5,3 cm or around 2 inches. There seems to be some crack repair on the tip but other then that it looks good to me. What I wondering is, if it's possible to describe this as a Daspletosaurus tooth? Or are there just to few information for a proper identification? Any help on what I am looking at is very welcome. Thank you!

Hello all, Recently acquired 2 teeth, found and sold together, that I would love some insight and second opinions on. Both teeth are described as Tyrannosaurid Indet, from the Judith River Formation. The seller described that he purchased them both together from the harvester, but due to the fact he was not the original collector, the information is isolated to the above information. Smaller tooth is 15/16" long, dark chocolate color, and 1/4" wide. Serrations are present on front and rear edges, with serrations starting midway on the front edge. Larger tooth is missing the front edge, appears sheared. Length is 1 1/8", width 5/16". Serrations present cleanly on rear edge, but again completely sheared from front edge. Color also deeper chocolate brown, but more horizontal banding. Can obtain more detailed and specific measurements of other needed dimensions if needed. Mainly I'm looking for a confirmation of Tyrannosaurid Indet distinguished from other theropods in the area at the time, as I have little experience positively IDing smaller tyrannosaurid material. I've actively worked on distinguishing Carcharodontosaur teeth from Rugops in the field in Morocco, but this is out of my field. All help is greatly appreciated! Will post more pictures in comments

Red Flag on Some Dino Material
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
Some very nice dinosaur material is being offered for sale but their identifications need some massaging. This beautiful tooth is being identified as Gorgosaurus from the Judith River Fm. Its a "Tryannosaurid indet. " since we cannot distinguish teeth between Gorgo and Daspletosaurus.. Looks like an anterior dentary position. This gorgeous rooted hadrosaur tooth is being identified has Lambeosaurus also from the JRF. Most seasoned collectors know its very difficult to distinguish teeth between different hadrosaur species. Quite a few are described from the JRF not sure if Lambeo is one. Best identified : Hadrosaurid indet. A Majungatholus tooth from Madagascar is also offered. Unfortunately the tooth is clearly not an Abelsaurid so it cannot be Majungatholus or properly called Majungasaurus. What is it I really do not know since very little is described from the Maevarano Formation. It also brings to question if the locality is correct. "This tooth was already posted on the forum" From the Judith River Formation the seller is offering this Troodon foot Claw. Only two photos were included in the listing so it was difficult to tell but initally it does not look like one more like an Oviraptorid claw. If you are interested I would ask for more photos so we can have a better look. From the Cloverly this bone is being offered as a humerus from a Tenontosaurus. I do not believe its one and have included the arm of a Tenontosaurus from my collection to see what one looks like. Its the bone on the left. Could be an ulna but not sure..jpg.554172f9834fed5a1353384f2c7cfb75.jpg)

On my birthday I got a juvenile gorgosaur tooth didn’t look special other then the colour but then I started to check it out and study it and instead of serrations there were small holes so I came up with a theory how juvenile tyrannosaurs didn’t have serrations until they got older yet I still need more proof to back up my theory but I found it interesting it was collected on a ranch in the Judith River formation not to far from the Canadian border it is 75 million years old here are some photos of it.

Seeking some scientific information about Judith River dromaeosaurids
fossilsonwheels posted a topic in General Fossil Discussion
I was hoping somebody on TFF might be able to point me in the direction of any scientific papers, research or information that members here might have put together regarding dromaeosaurid theropods from the Judith River formation. This is not really about identifying any teeth, though I do have one from that formation. I am starting to do my research for the education program and am looking for scientific information. From what I can gather, there is a possible Saurornitholestes species and of course the dinosaur I have seen referred to as Julieraptor, which is a interesting story all on its own. I have also seen Dromaeosaurus listed from that formation. I would like to sort out what is known and unknown from the formation and the best way to present our "raptor" tooth to the kids. Any help links or suggestions as to where I might find more information on this would be much appreciated -
Here’s one that has me scratching my head. It’s a bone I found in the Judith River Formation of Montana recently, I picked up these two pieces and later realized they go together. They’re definitely placed properly, but the shape is strange and I can’t ID it. My initial thoughts were some type of hadrosaur toe bone, but I can’t find any close matches online. What are y’all’s thoughts on this one?

I believe I know the answers but like to confirm the ID's and raise a red flag if appropriate. Seller is offering the following from the Judith River Formation of Montana Saurnitholestes Tooth 1/4" Aublysodon Tooth 3/4" Daspletosaurus tooth 1.4" Daspletosaurus tooth 7/8"

Here are some small fossils I found back in the summer of 2017 in Montana up in the Judith River Formation. 1. Small reptile vertebra? (.5 cm) 2. Assorted tiny bones several of which are likely from birds. 2a. Hollow at the broken end (about .8 cm). 2b. Hollow at both ends (1.2 cm). 2c. Hollow at both ends as well, looks like limb bone. (1.5 cm). 2d. Appears to be hollow on both ends (.7 cm).

Hello! I have purchased this nice raptor tooth from Judith River formation. I think this is saurornitholestes tooth. Am I correct? Thanks in advance!
-
I just recently bought this on a certain auction site (that I've been spending too much time on lately). The seller said it is most likely a raptor caudal vertebra. It was a surface find from the Judith River Formation about 30 miles north of Glasgow, Montana. Is the seller's ID accurate?

Hard to keep up to new discoveries and when I see one from the Judith River Formation from Montana even though its a year old it attracts my attention. Material from this fauna is constantly being offered for sale and can be collected with access to ranches. A new ceratopsid, Spiclypeus shipporum from the lower Coal Ridge Member of the Judith River Formation was described and I've attached the article for viewing. I want to remind collectors that its not possible to know the species of teeth, horns and unguals being sold from large bodied ceratopsians. So be careful of sellers trying to put species names to their offerings. This figure was included in the paper and what's interesting is it shows what dinosaurs have been described from this fauna and material that as only been identified to a family level.

New Species Of Horned Dinosaur With Flashy, Butterfly-Shaped Frill Discovered In Montana
JohnBrian posted a topic in Fossil News
From Western Digs: One of the most abundant and diverse families of dinosaurs from the Ancient West has a new member among its ranks. Two new specimens of ceratopsid, or horn-faced dinosaur, have been found in separate locations in the U.S. and Canada, and their shared features are so distinctive that paleontologists say they “definitively” represent a species that’s new to science.
