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

Small unidentified theropod tooth from Morrison Formation, Wyoming
Sauroniops posted a topic in Fossil ID
Hello there. I recently received a small theropod tooth from the Morrison Formation, without any ID. Part of the tip is missing/worn out. At its longest dimension, the tooth measures 1,1 cm. The serration count (Both mesial and dermal) are 6-7 serrations per mm, and about 18-19 per 3 mm. Anyone who's got a good guess, feel welcome to drop a comment here, cause I have no clue if this is a baby Allosaurus, or a small Marshosaurus, Ornitholestes, Coelurus or something completely different.- 11 replies

Possible Suchomimus or theropod toe bone from the Elhraz Formation?
msantix posted a topic in Fossil ID
Hi, Saw this for sale and was just wondering if this looks like a theropod toe bone or if it could be narrowed down? it is labelled as from Suchomimus but it could instead be from a croc or another theropod if not Suchomimus. It is 10cm in length and comes from the Elhraz Formation in Gadoufaouna, Africa. Thanks. -
HI, I purchased this Unidentified theropod tooth a few years ago from a seller that sold it as a "Raptor" tooth. It is from the Kem Kem beds from Morocco, during the late Cretaceous Period. It is 1.3 Centimetres (1/2 inch) long. The seller also mentioned that it may likely be from an Abelisaurid. I think that it is most likely an Abelisaurid tooth and I am looking forward to updating it's identification tag in my collection. Yet I need to be certain that I am correctly identifying this tooth. What are your thoughts about what this tooth could be? I apologize if I spelled/addressed the names incorrectly and I would thank you for the correction. Feel free to ask for better quality pictures if you need any.

Ok, I have given a go at doing some ID on this myself, using the very helpful "identifying theropod teeth from the Hell Creek/Lance Formation." thread. But hit a brick wall. So, if anyone could A) Let me know what this tooth is and B -- If I am on the right track with my amateurish ID attempts, that would be amazing. So, I got to eliminating it as being a Nano (Because Nano teeth are apparently rectangular and this is quite ovalish. And eliminating it as being a small version of a T-rex tooth because it isn't fat and the tip doesn't look right. And eliminated Archaeoraptor as it being a bit big. Eliminated Dakoraptor because the recurve isn't enough. This is my first time having a proper go at IDing a tooth for sale beyond googling similar--so odds are I've missed something obvious or got it completely wrong. So, it is labelled as theropod Nanotyrannus, Lance Formation, 0.5 inches in length. Any help, as always, much appreciated.

I obtained a 1.5 inch tarbosaurus tooth from a very old collection decades ago. One that had not been prepped since the day it was collected. I decided to finally prep it and wanted to show you all the final product. Very happy. Amazing serrations.

Digging through some bags of bones, looking for something to work on during the virus crisis. Glued the pieces I and collected and this is what I have. I believe this was collected in Wyoming, near Newcastle. What is it? I think it is Theropod, possibly a partial pubis bone. 10.5inches long, 1.5 inch flat bottom, approx 1 inch depth large marrow pores.

Hello, this spring break I found this vertebra in late Campanian sediments from southern Coahuila, Mexico. It comes from the Late Campanian, Cerró del Pueblo Formation, around 73-71 million years. This was found along with marine and terrestrial fossils. It is about 1 cm long (3/8) of an inch, 1 cm in width, and 1.1 cm in height. I want to know what type of dinosaur this vertebra belonged to and whether it’s a caudal vertebra or not. My thoughts on this specimen at the moment, is that it’s probably a caudal (tail) vertebra from a small theropod dinosaur, something like a dromeosaur or a troodontid. I hope some dinosaur experts on this forum can give me more insight on this small vertebra.. Side view Other side Front view Bottom Top view

Hi I’m wondering what Ceratosaurus and other horned Theropods used there horns for? I’ve heard it was display but I’ve also heard it was for pushing rivals. Is there any evidence for these? Thank you!!

I have a theropod tooth that has hard rock matrix attached to base. What is the best technique to remove it safely? Thanks in advance.

Hi, I saw this tooth for sale and i am wondering if it looks like it could be a Ceratosaurus tooth. I read something about Ceratosaurus teeth having vertical ridges on the inner crown so i think it could possibly be a good match. It is .75 inches long and comes from the Morrison Formation in Wyoming. Thanks.

Hello Everyone, I have had this beautiful Argentine theropod tooth for 18 months now and the previous owner 25-30 years before the ban was introduced. The locality information is a bit flakey, however I thought it would be worth a try to get some kind of ID if possible if there are any Argentine friends out there with some information to hand. I have taken some measurements as follows: Distal - 12 per 5mm Mesial - 12 per 5mm MCL - 18mm MCW - 10mm crown height - 39mm If any further measurements are needed let me know Thanks!

Theropod Metatarsal ID request Verification
TyBoy posted a topic in Is It Real? How to Recognize Fossil Fabrications
Looking for confirmation on this theropod bone being sold. Seller is identifying it as a theropod (Anzu?) Arctometatarsal from the Hell Creek of Montana, Powder River County.. 10.4" Long. They indicate it cannot definitely provide an ID but the giant raptor Anzu Wylie is a likely candidate be cause other material from this theropod has been found at the quarry. What is a Arctometatarsal?

Just bought this vertebra. Small thing, just about 4,5 cm in length. Added a 1 euro coin for size reference. Obviously the spine on top and sides are gone. It was sold as a 'unidentified' theropod (caudal) from Ifezouane Formation, Kem Kem. I was wondering if people here could come to a better ID. I suspect it might just as well be crocodilian but to be honest: I'm fine with whatever it turns out to be. Didn't pay much for it anyway. So, is this: - a dinosaur or croc? - theropod - species (?) Would love to hear your opinions!

Hi all, I posted this tooth for ID a while back. Conclusion was that it could be a Dakotaraptor, maybe, maybe. Since then I am going back and forth on the ID, basically on a daily basis So I decided to take more & new images, measure it thoroughly, put it up again, and kindly ask for your help. It was found in the Hell Creek Fm, Powder River Co., Montana. Measurements are: CH: 2.08cm CBL: 0.8cm CBW: 0.42cm Serration count per 5mm is mesial 24 and distal 18. What makes it hard for me to judge: the shape of denticles is between round and chisel (?), the tiny mesial denticles, and the position of the carinae. Lowest part of the mesial carina is sheared off, but I would not expect a twist - looking closely it would end either half way or 1/3 from base. Any help is highly appreciated!

It's nothing particularly exciting, but I just wanted to share what is possibly the prettiest looking Spinosauridae tooth I've ever seen. The enamel patterning on it is gorgeous, and very different to what I've come across on run-of-the-mill Spino teeth before. Both carinae and tip are also beautifully preserved. There is a pretty smooth enamel texture and no fluting, plus it's even sporting an offset, short mesial carina for an extra bit of personality. (51mm) Anyone else want to share their favourite colourful teeth?

I know specimens from the Kem Kem are some of the most common things found on the market, but with so much undescribed material, it's a favourite location of mine for finding those fossils that are just a bit odd and often overlooked. So here are some of my theropod teeth from the locality to date, that don't quite fit the usual Spinosaurid & Carcharodontosaurid profiles: To start with, a theropod indet. tooth with a very unusual profile, and unique (for the locality) mesial carina that ends naturally above the midline.

Genuine theropod dinosaur egg?
MohammadAAK posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello all, I saw one seller online listing this piece for auction. I'm interested in bidding but the fact the seller is from Taiwan worries me. Other than that, the egg looks nice. Seller says it might be a small tyrannosaurus or large therapod egg. Locality is noted as "East Asia", which I assume is china. And the description says this is from an old Chinese collection exported in the 80s. Cretaceous of East Asia. Best wishes

Hi, does anyone know if theropod bones are completely hollow. I saw this for sale and was wondering whether it was theropod or just float because it wasn't fully hollow but had gaps and holes, the website wouldn't allow me to copy the image though.

So I've just added another new theropod tooth to the collection from the Kem Kem. I'm going to go out on a limb and say it's another contender for a potential dromaeosaurid tooth? • Very laterally compressed • "Pinched" to small degree at base • Mesial carina terminates well above the base • Slight twist to mesial carina • Mesial serration count (midline): 6 or 7 per 1mm • Distal serration count (midline): 3 or 4 per 1mm There are also interdental succuli present between distal denticles; not something I've particularly noticed on other dromaeosaurids, so I'm not sure if that has any impact on tentative ID? Lingual side?: Lateral side?: Cross section: Mesial face: Distal face: Pinch at base: Close-ups:
