Hello, anyone able to id this for me? A theropod tooth 1.33 inch From Tiourarén Hill, Tenere Desert, Niger A bit battered, but there are serrations visible. Thanks for the help.

This tooth is from Harding County, Hell Creek formation. Now--it is tiny. 1mm long, so is the smallest tooth I own by far, but it has quite clear serrtations that can be photographed. It came with a few others and this one stands out because of its fatness and squatness (most of the others are long, relatively speaking) I am wondering if possibly, maybe, hopefully .... I may have a baby/infant Rex? Now, unfortunately, the base is a bit thin--but could that be because of the size of the tooth? It's quite an unusual one and hope it can be ID'd

Hi all! I've had this tooth in my collection for a while now and I want to give a more narrow ID. It was originally sold to me as belonging to Ceratosaurus sp. and even then I knew how bold a statement that was and have had my doubts about it. My knowledge on Morrison Theropod teeth is very limited so any of your help is appreciated.

Hello, I got this tooth that was labeled "raptor" from the hell creek fm. In the ad--and now in-person too--I think it's a T. Rex tooth. The trickiest part is getting anything on the mesial carina, there's quite a bit of wear / weak / lack of denticles. I'd love to get your thoughts on whether there's enough here to stamp it T. Rex. About 3/mm distal Attempts as mesial carina (strong twist)

Recently got this partial theropod tooth, found in Niger, Gadoufaoua. Likely a Eocarcharia Dinops tooth. If anyone can help me confirm this species, that would be amazing!

Hello! I apologize for my long absence. I transferred over to UW-Madison back on January, so I’ve been busy with school and life. I have messaged other members in the past about this enigmatic theropod tooth that I had purchased from a friend here on the forums a few years ago. I’ve been told that it is either Dromaeosaurid or Tyrannosaurid, but I’m still unsure. Since I am interested in studying vertebrate paleontology studying the Mesozoic era, a paleontologist at UW-Madison invited me into the lab and we got a decent enough picture of the (rather worn) serrations on this tooth. He’s not quite sure himself, mainly because he mostly works with Triassic materials pertaining to Phytosaurs. Regardless, I got this tooth for a great price and I still love it.

Hey all, Thanks for taking a look here. Does this look dromaeosaurid to you? It's from the hell creek, it's 13" long and a about 1.5" wide and deep. Thanks for your time.

Another Kem Kem tooth (17 mm). Pretty sure it is Abelisaurid, but it does have some noticable differences with my other Abelisaurid teeth. It is less compressed and one side of the tooth (the lingual?) is pretty flat, while the other side is not. Am I right to assume these are probably just positional differences? Could this be a more anterior tooth? Thanks!
-
Hi all! I received this tooth (5 cm) in my mailbox today. My best guess is an anterior Carcharodontosaurid tooth, but I am not entirely sure. It is pretty fat and the distal carina is displaced. What do you think? Thanks!
-
I'm thinking of buying this tooth. It was listed as "raptor, but looks like theropod indet. to me. Or, it might be one of those teeth that actually are dromaeosaur. What do you guys think? It's about a half inch or 1.2 cm.

Hey guys, I obtained this tooth at tucson this year direct from the finder. It is from the Judith river formation, hill county, montana. 2.2cm long. got a characteristic V shaped flattened area on each side of the tooth, which i have seen in nanotryannus but it can't be that ? as nano doesnt occur in the judith river.... or it's has been mislabelled? My question is tyrannosaurid or dromeosaurid? if so what could it be? thanks for your time. @Troodon

Publication on French Jurassic Dino's using PRIVATE collections FANTASTIC
Troodon posted a topic in Fossil News
WOW a eureka moment..... a publication using specimens in private collections...so It can be done and should be done. My hats off the the authors and hopefully it sets off a new standard for publications. One of the authors is well known paleontologist Eric Buffetaut Abstract: Dinosaur remains found at the Vaches Noires cliffs (Calvados, Normandy) have usually been discovered by amateur palaeontologists. The bones come from carcasses which drifted away from a nearby land (Armorican Massif) during the upper Callovian and lower Oxfordian. Most of these bones belong to private collections and are hardly accessible. Consequently, many of these bones were never described. Thus, and for the first time, private and public collections are gathered to obtain a global vision of theropod remains from the Vaches Noires cliffs Excerpts from the paper "they are essential for the study of theropod diversity from the Vaches Noires Cliffs, even if they are isolated and their precise stratigraphic origin is often unknown" "The aim of this study is to gather and describe bones from 6 different collections, most of which are private, and to provide new insights on known specimens" Wow again.. getting a good understanding of the fauna is more important than putting up walls on why not...nice job authors it would be nice to see that in North America where a few of our paleontologists even frown at looking at private material. https://sciencepress.mnhn.fr/sites/default/files/articles/pdf/g2022v44a12.pdf

Hi everyone! I've been going through and identifying some small serrated kem kem teeth and was hoping for some verification. I'm fairly certain the first three are Carcharodontosaurid and the last one isn't but I just wanted to make absolutely sure. CH is crown height CBL is the length of the base CBW is the width of the base

Hello - Some time ago I bought two partial bones, both from Kem Kem beds, Morocco - The specimen on the left in the photo in my opinion could be the final part of the ischium of a theropod dinosaur (roughly 21cm x 21cm- possibly Spinosaurus?) and the other specimen a partial vertebra (21cm x 13cm) of the same species - I'm not an expert and I'd like to know other opinions about the ID of the two fossils - Thanks in advance, Fabio

Two in one post: possible Allosaurus tooth and Marshosaurus tooth
AJ the Tyrant posted a topic in Fossil ID
I’m wondering if these two teeth (both are from the Morrison Formation in Moffat County, Colorado) have been identified correctly as Allosaurus and Marshosaurus. Here are the measurements of both: Allosaurus: 4cm long serration count is 10/5mm on anterior and posterior carinae base length is 21mm and base width is 13.5 mm (note from dealer: Please note that the base of this tooth is broken and the transition of enamel to root is not present. The base measurement may have been larger.) Marshosaurus: 4cm long serration count is 18/5mm on anterior and posterior carinae base length is 15 mm and base width is 8mm (note from dealer: Please note that the base of this tooth is very near the enamel to root transition a represents a fairly complete tooth.) The serrations on the anterior keel of the tooth extend two-thirds of the distance from tip to base. Images seem to be weirdly mismatched, but I think it’s pretty easy to tell which pictures match with which.

Since I bought a couple of (very nice) Abelisaurid teeth from Kem Kem, which I initially thought where Dromaeosaurid, I am on the lookout for potential Dromaeosaurid teeth from Kem Kem. I think this tooth (1.9 cm) might be a candidate, but I have been wrong before. What are your thoughts? Should I ask for better pictures of the serrations or a serratiom count?

Triassic Redonda Formation of New Mexico- Possible Theropod teeth?
Crowmagnon posted a topic in Fossil ID
I have gone through all of my Redonda formation teeth, and think these ones are likely theropod, possible Coelophysis. Any insight would be greatly appreciated! Tooth 1: 7mm long, serrations ~8/mm along middle of posterior edge.

From the album: Nanotyrannus35's Dinosaur Teeth
A bit over an inch long. -
Hi Everyone, I recently purchased this feeding worn theropod tooth that the seller had listed as unidentified, with it likely being a Tyrannosaur tooth. It is .42 inches long (straight line) and comes from Hell Creek. I was thinking it might be a Acheroraptor tooth, but its tough to tell due to the amount of feeding wear and enamel damage. I was wondering if anyone else could help me concretely identify it. Thanks!

Hi, I'm interested in this fossil that is listed as a Theropod Ilium bone from the Kem Kem (21cm in length). I wanted to ask if there are enough diagnostic features to identify it as belonging to a theropod or does it resemble something from a crocodyliform instead? Thanks!

So I was wondering if anybody would want to trade any theropod teeth. The stuff that I will trade for theropod teeth are just about all from the green river formation. I will trade a matrix-free stingray barb, a partial eohiodon, or a mostly prepped priscacara for any theropod teeth, including spinosaurus. I also have a couple 2 inch bone valley megalodon teeth that I would be willing to trade for theropod teeth. Pm me if you want to trade.

Judith River Formation, Montana Theropod Tooth Identification
Joseph Kapler posted a topic in Fossil ID
As I understand it there are three described Tyrannosaurs from the Two Medicine and Judith River Formations -- Albertosaurus, Gorgosaurus and Daspletosaurus. I have read that research done on teeth from these three Tyrannosaurs has concluded that isolated teeth are statistically impossible to assign to a specific genus because they are so similar. Now, I know that there are a number of form members that have quite extensive collections and have spent time and money studying these teeth, and it is my believe (having spent 35 years in the minerals exploration business) that private researchers probably know as much if not more than the academics. It has been my experience that academics rarely spend their own nickel buying their own equipment, conducting field work, and collecting specimens to conduct their research. I also know from first-hand experience that statistical evaluation alone can lead one down the wrong path and to the conclusion 'it needs more study.' While I am not a 'true' collector, my interests are hands-on fossil and mineral specimens that tell a story to interest kids in general science. My question is are there any general observations about Two Medicine and Judith River Formation theropod teeth that one might use to assign a probable genus to these teeth? It seems that assigning a genus to isolated teeth from the large adult theropods is quite possible, juvenile teeth seem more problematic -- but juvenile teeth are what I can afford. I would appreciate observations you might be willing to share.
