Hi there. I'm looking at this tooth listed here as coming from the Nemegt Formation. I'm curious as to what everyone else makes of it. The seller states it is a "raptor" tooth but is unable to make any further guesses, I feel that is quite far from accurate but Nemegt is a blind spot for me. I know a picture like this is far too unclear, but I feel the morphology of this tooth is interesting enough against the seller's I.D. It's a bit late right now so I'm not going to hit the literature for the time being. I will say that the term raptor being used over any taxonomical nomenclature is enough to trigger my scepticism irrespective of their reasoning.

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

Hi all, I have here what was claimed to be an Alioramus tooth with jaw fragment from the Nemegt Formation. The entire fossil measures 2.6 inches tall, and the crown section is 1.4 inches tall. I haven't had much cause to suspect its authenticity as I knew the dealer obtained a stock of Nemegt Formation fossils, and another expert I trust examined the pictures and determined it is authentic, but was broken and re-attached. Recently however, another expert I trust claimed that this is in fact a Kem Kem crocodile based off the pitting of the jaw, the thinness of the jaw which matches a croc rather than theropod profile, and the coarse red gravel seen underneath the fossil (as I am aware, Nemegt fossils are covered in red sand too), and the so-called crown isn't even a tooth. What are your thoughts on this?
