Hello, I have my eye on a few teeth. If someone can take a look and see that they all look ok, are as described etc, that would be great? 1 - A Tyrannosaur premax from Two Medicine. 2.2 cm -- No county known, unfortunately. I know this is a tricky formation that overlaps many counties, so I may leave this one if it cn't be confirmed as being from there via preservation/colorisation. 2 - Tyrannosaur tooth from Judith River. Lewistown, Montana. 1.7cm, sold as a juvenile. The crack visible seems like just a minor bit of damage and isn't anything to worry about? It doesn't

Not very much is published on rare teeth. I'm trying to compile some information so that collectors have something to look at. Might not get them all the answers but its a start. Any discrepancies seen in this info please let me know. If you see anything published that can add to those listed please let me know.

Chenanisaurus Barbaricus Tooth? Or Carch?
Kurufossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Came across this tooth labeled as an abelisaurus belonging to chinanisaurus barbaricus from the Maastrichtian supposedly found in the phosphate mines of the Ouled Abdoun basin. Looks pretty thick to be abelisaurus and comparable to an extent to some carcharodontosaurus teeth. Is there a way tell the difference or will there need to be more specifics involved. -
Howdy! This is a dromaeosaur tooth from the upper Dinosaur Park Formation. I’m pretty sure it’s Saurornitholestes, but based on the size (1cm L) and shape, is it possible to tell the position in the mouth? (Ex maxilla, dentary, predentary?)

Isolated teeth from the Tacuarembó Formation of Uruguay have revealed the first Megalosaurid from South America. The teeth have strong resemblance to Torvosaurus and as such the Megalosaur from Uruguay and Tanzania are suggested to be from Torvosaurus. It is paywalled but the abstract describes the features of the teeth. https://www.sciencedirect.com/science/article/abs/pii/S089598111930505X

Theropod teeth from Uzbekistan typically are not seen for sale other than those from Tyrannosaurs. Opportunities always make themselves available so I decided to put a quick post out on those that have had some scientific research. I also think it's cool to see some of these teeth. We are looking at teeth from the Bissekty Formation, Touronian in age from the Kyzylkum Desert from the following two locations Dzharakuduk and Uchkuduk. There are younger and older deposits in this Desert but all of the teeth sold appear to be coming from those two localities. Changes to what is presented here most

Looks like we have a number of new members who are interested in Dinosaur teeth so I thought this topic might be good for them and serves as a reminder for more experienced collectors. Let me start off the discussion by saying that identifying isolated dinosaur teeth is a challenge even for more experience collectors, so its not a trivial task. There is no one cookbook that has all the answers, just a number of technical papers and articles that provide some information on different localities or species. Many of teeth that are sold online carry identifications that dealers have

I noticed a number of online suppliers offering Troodon teeth that actually belong to the genus Pectinodon. Thought it would be a good discussion item for a focused post since they can get confusing with the various morphologies of Pectinodon teeth. I'll use publications to illustrate my points and reflect all Campanian & Maastrichtian age teeth of North America. (Edit) A new paper published late in 2017 has turned this taxon upside down. I will try to reflect those changes here but it should not change alter how they are identified against Pectinodon teeth. Specim

Hello all, I was browsing on our favorite auction site and I found a dealer who is selling a pair of Ceolophysis teeth for a rather cheap price, which sent off a warning flag in my mind. The dealer claims that these are from the Bull Canyon formation of New Mexico. Are these teeth real or are my suspicions correct?

Saw this tooth online recently, it already sold but it was listed as a Tarbosaurus Tooth but it reminds me more of a carcharodontosaurus tooth but then again I am unsure nor familiar with tarbosaurus teeth, what do you guys think? I have included all photos in the listing.

Is This Torvosaurus Tooth Heavily Repaired/Fake?
Kurufossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Can across this one recently on our favorite auction site, a torvosaurus tooth from colorado. Though with no intention of buying especially at the high price tag it is at I have my suspicions, the seller claims it its 100% no repairs or restoration. Looking at the pictures I highly doubt it as it looks extremely repaired to me and some of it especially in the picture zooming into the tip reminds me of the little air holes found in fake cast trilobite. Idk how much is repaired or even if the whole specimen is fake, I'd be interested to hear what you guys think. Definitely a gigantic red flag to -
Identifying Theropod Teeth from the Hell Creek/Lance Fm
Troodon posted a topic in General Fossil Discussion
A few years ago most of the smaller theropod teeth from the Hell Creek/Lance Formations were identified based on teeth from the Campanian assemblages of North America. Over the past couple of years new discoveries have shed new light on the theropods of the end of the cretaceous and new species have been described. I have addressed these on separate topics but decided to put all of these together to get a better view of the current picture of the upper Hell Creek and Lance formations. If you see any omissions or errors feel free to let me know. Tyrannosaurs: There are t- 17 replies
