Nanotyrannus teeth is real?
Josesaurus rex posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hola a todos. He estado viendo publicaciones durante mucho tiempo con dientes de nanotyrannus. Lo que me gustaría saber es si usted, que tiene más experiencia en la recolección de fósiles, podría identificarlos como pertenecientes a ese dinosaurio o no. De antemano muchas gracias. (Translated: Hello everyone. I've been looking at posts for a long time with nanotyrannus teeth. What I would like to know is whether you, who have more experience in collecting fossils, could identify them as belonging to that dinosaur or not. Beforehand thank you very much.)

So, this theropod tooth came in a lot of a bunch of other teeth I bought as part of a box lot of about 20 Kem Kem theropod teeth. Most of it was in pretty bad condition, and there wasn't really provenance attached to them, but I paid literally pocket change for them. But to get back on point, I wasn't sure if this was an Abelisauridae, or a Carcharodontosaurus, possibly an indeterminate theropod. My gut feeling is that it's an Abelisauridae, but I'm not sure, Abelisaurid teeth tend to be much more easily recognizable, and I have a lingering doubt on this one. Measurements are in centimeters. Assuming I did the serration density count right, both sides are 12/5mm or 2.4/mm

Hi, I'd quite like this. Advertised as an unidentified theropod vert from Portugal (Lorinha formation). 5.3 cm x 5.2 x 4.5 cm. Is it theropod as opposed to croc or other dinosaur? Any thoughts would be great. Thanks

From the album: Dinosaurs
Species: Carcharodontosaurus saharicus Age: Cretaceous (Cenomanian), c. 95 million years ago Location: Kem Kem Formation, Morocco A lot of the enamel is missing, but an otherwise well-preserved tooth of Carcharodontosaurus saharicus, some would prefer labelling Kem Kem Carcharodontosaurid teeth as "Carcharodontosauridae indet." on account of Sauroniops pachytholus, but a 2020 study declared that it was likely synonymous with C. saharicus so I am comfortable with just referring to it as a tooth of Carcharodontosaurus. -
Last year when things weren’t so complicated with COVID, we managed to have hunt for dinosaur footprints on the Yorkshire coast. Here’s the beach looking across to Scarborough in the distance. Here are some examples of the prints we came across: Nothing fantastic but all theropods. Heres one in a block that was carry-able: I finally got around to cutting the block to size today although it was freezing outside. So here you go, Theropod Footprint, circa 5 inches long. Middle Jurassic Bathonian (168-166 million years) Scalby Formation Long Nab Member Yorkshire Coast Nr Scarborough Thanks for looking

Spinosaurus Tooth Real, Matrix or Glue
Mister Forelle posted a topic in Is It Real? How to Recognize Fossil Fabrications
I just got a spinosaurus tooth by my girlfriends dad for christmas and i have a few Questions: 1. Is it real or how much of it is fixed up with some kind of matrix? 2. What is that bright white part glimpsing between the sand? 3. Should i try to free the tooth from the dark/sandy part, to reveal his real beauty? 4. If yes, how? Thank you for your time! -
Good everyone. So I was fortunate enough to be able to buy some specimens from an old collection. Unfortunately the husband had passed away and the misses was left his collection from 30+ years. This claw had been tagged as a Spinosaurus claw which I’m pretty confident it is not. So I’m hoping you guys may have some input. I cannot tell you anything about location because no one other than him would know. So I understand that the ID will not be 100% and that’s fine. It definitely has had some repair work done to it. So thank you in advance for any input. Sincerely, J

I was recently offered a few teeth and this was one of them, the seller says it a Theropod tooth from the Taldint anoual formation but I’ve never herd of the formation before. Could anyone help? Thank you for any feedback!

Hello there, so in New Zealand there is an indermitate theropod dinosaur most commonly referred to as Joan Wiffen's Theropod. I am extremely confused on what the specimen actually is because some sources say the specimen is represented by a toe bone while others say a partial vertebrae. Also if anyone could tell me the specimen number (GNS 00 000, for example) or link a scientific paper explaining actually what it is i would be highly appreciative, thank you

Hello, This is probably a long shot, especially because the ends are broken off, but I was wondering if someone could have a go at IDing this very small theropod claw from the Dinosaur Park Formation. I figured that the relative thickness above and below the blood groove might be diagnostic, but I know how hard these can be to ID at the best of times. After consulting this thread, my best guess so far is that it comes from a troodontid, but I'm skeptical about this simply because of how rare they are. Thanks!

Hi, I have another query about a possible theropod bone, this time it is from the Lourinha Formation in Portugal. I think it is a caudal and the seller lists it as a Theropod indet fossil but I wanted to confirm if it is indeed from a Theropod because it does look a bit similar to some croc verts I have seen. The fossil is 5.3cm in length. Thanks.

Hi, I hope the pictures are adequate for a possible identification. This is being sold as a theropod limb bone from the Kem Kem. The seller states that it arrived broken and it was hollow like a theropod bone (but filled with sand and has had a few glued repairs). It is 23.5cm in length and I am wondering if it does look like a limb bone and if it might be a Spinosaurid bone since it reminds me a bit of a Spinosaur phalanx (although the seller lists it as an unidentified dinosaur). Thank you!

Mongolian carnivore tooth with jaw fragment. Is this a croc or theorpod?
-Andy- posted a topic in Fossil ID
Hi all, I had posted about this tooth years ago and the conclusion back then was that its preservation was too poor for any proper ID. I am hoping that with new information we can at least determine if this is a crocodile or theropod. I discovered today that this tooth preserved some serrations First up, this tooth was acquired from a source with many Mongolian material. He called this an Alioramus tooth but I am not comfortable calling it that yet Secondly, a museum curator (who has handled Mongolian material) examined this tooth in person. He concluded this tooth was indeed Mongolian but he could only say it's a carnivore. Unfortunately, we are unable to determine which part of Mongolia it came from. The crown is 40 mm in a straight line. I have quite a number of croc and theropod teeth and this tooth feels much closer to a theropod than a crocodile both in terms of morphology and size. However, I am not unbiased in my ID, and the shallow jaw fragment is throwing me off. Assuming this is indeed from a tyrannosaur, I'd expect the jaw to be much deeper. Please let me know your honest thoughts, thank you Comparison of tooth to a cf. Daspletosaurus from the Judith River Formation

Hey all! Came across this little guy. Curious if anyone can tell me what it is? Its small, about 1.5cm in length, and slightly curved. It has two serrated edges, although they aren't on opposite sides - more like they are on one side of the curved edge (?). Hope someone can shed some light, Thanks!

Found in New Mexico on private property, not far from Morrison Formation...Circled in red highlighter is what appears to be a talon...last photo is of the opposite side..

Hello! This tooth has been offered to me. The id is theropod ind. It has very small serrations... From Cloverly Formation. What do you think? Thank you so much!

Hello, if anyone can take a look at this, that would be great. I know most from Abington I've posted have turned out to be plesiosaur, but hooefully this is as described and is preserved enough to get an id. And is easier to identify being sold as theropod rather than sauropod Theropod/carnosaur vert Abingdon, Oxfordshire, Jurassic 11cm x 9.5 x 5.3 Many thanks

Hello everyone ! Here is 0.65" tooth from carter country ,Hell creek formation , Montana . I personally think that it belong to Theropod maybe ? (I saw very faint serration in this tooth) A good friend of mine told me that due to weird shape of this tooth it could be a Pre-maxillary tooth of maybe Nanotyrannus with feeding damage at the tip. What do you guy think about this tooth ?? as always thank in advance . Guns

Found this thick bone piece in a new jersey cretaceous creek and wonder if its possible to maybe id since one side has a distinct rough texture while the other is flatter and striated, I would guess either large turtle, mosasaur, or dinosaur. My friend joked its a theropod maxilary skull fragment, but we all know around here that material seems close to impossible to come across haha. Interested to hear any other thoughts.

Hi all, I bought this tooth recently on an auction site and was wondering what you folks think. The seller bought it at Tucson Fossil show but lost the ID card with the Formation on it, so the locale is missing. Info on the tooth: 1 inch long Supposedly from Madagascar

Hi, I received this teeth recently from another forum member and was wondering what others think. These teeth were acquired at a German Fossil Show and were apparently found near the Chinese border. I think they look kinda like Carch teeth. Let me know what you think. The first tooth is 1.1 in long and the base is .3 wide The second tooth is 1.22 long and the base is .5 wide

Hi! I can get this incredible and rare tooth. It is from the Atlas Mountains, Morocco so it’s a Jurassic tooth. Any idea about posible ID? Thank you so much!

Spinosaur Tooth - Comoposite?
BellamyBlake posted a topic in Is It Real? How to Recognize Fossil Fabrications
This is a large Spinosaur tooth. It has obvious repairs, and some restoration horizontally along the middle of the tooth. However, I'm wondering if it looks composite. The claim is that it isn't composite, but I'm suspicious. -
Hi TFF, I am a Dromaeosauridae enthusiast and have been collecting online for a little while now. I want to thank the members here for getting me educated on so many aspects of fossil teeth identification. I want to share my small collection in the hopes this is helpful for some of you in the future. Your critical input is highly appreciated, as always! #1 First up, one of my treasures, a robust Deinonychus antirrhopus tooth from the Cloverly Fm. A big thanks to @StevenJD for letting go of this one – much appreciated! Note the asymmetry in the placement of the carinae, best noticeable from the top view. #2 Representing the Judith River Fm., a cornerstone of my collection, a 1st left premaxillary tooth of Dromaeosaurus albertensis. I just love the way the mesial carina ‘folds’ onto the lingual surface. #3 Another premaxillary tooth from the Judith River Fm., a Zapsalis abradens with prominent ridges. The mesial carina has a nice twist, the cross section looks rather symmetrical, so likely not a 1st or 2nd premax. Distal denticles are hooked towards the tooth tip, but no mesial denticles are present and the tooth is not recurved. So, for now it is labeled as cf. Zapsalis abradens after Currie and Evans 2019, but could eventually be re-labeled as Saurornitholestes langstoni.
