Hey guys this is my first tooth purchased. I bought it from a fossil website because I thought that would be a safe bet with my lack of experience. I know I overpayed for the tooth, I payed $150 for the tooth. After receiving the tooth and actually holding it, the tooth appears to seem completely reconstructed. I just wanted to know some opinions, some spots almost appear completely covered with glue.

The theropod landscape of the Kem Kem deposits continue to be more muddled with new discoveries and research but that should not surprise anyone. I've made several post about multiple Spinosaurid and Carcharodontosaurid in the Kem Kem and it continues to be supported by recent publications. The attached paper describes a femur that supports the concept that Abelisaurid's were in the Kem Kem. We are seeing teeth...so that's good. The paper however looks at the region: Figure 2 below, included in that paper, identifies the main theropod fauna of the region. The abbreviation KKCA under Morocco stands for Kem Kem Compound Assemblage. Please note that under KKCA there are two Spinosaurids mentioned Sigilmassasaurus and Spinosaurus indet. The paper concludes that there is to much ambiguity in the material studied to assign it to Spinosaurus aegyptiacus and further reevaluation is needed. Boy that sure puts an arrow through Ibrahim's Spino redesign. It also states that Kemkemia auditorei, paper attached, may be a crocodyliform or like the paper suggest a spinosaurid. The figure also shows two Carcharodontosaurid: Carcharodontosaurus and Sauroniops. Also Rugops is shown exclusive to Niger. More changes will come and hopfully in some lifetime we will have answers. So if you want to follow proper convention all Spino and Carch material should be identified has indeterminate but if you have that need to have a species name that's okay no one will know.

I am new to this forum, and I was pleasantly surprised with the friendly and immediate, helpful, educated responses I received when I asked for help ID-ing dromaeosur teeth! Thank you Troodon and Runner64 for your help! This seems like an active, educated forum where lovers of prehistoric life can gather to discuss fossils, and the like. So, I would like to show off my fossil collection, and discuss things about the small amount of material I have in my personal collection! Feel free to show me your collections as well, I would love to see them! So without further ado, on to my fossils!

I just got this strange tooth that's almost 3.5" long that I assumed it came from a Cacharodontosaurus. But upon closer inspection when I got it the shape of the tooth doesn't look flattened nor blade-like but seem to be very bulky unlike typical Carch teeth I have seen. So I was wondering if this is a special positional tooth that doesn't fit the standard shape of normal Carch tooth? It's also slightly bent and twisted as well, not sure if that's natural or some form of pathology. The previous owner thought it's a Deltadromeus tooth but that doesn't seem likely since Deltadromeus teeth (or those theropod teeth attributed as) shouldn't be this big, but I could be wrong. What's are you guys opinions on this?

Delta, Dromie and Carch are some of the most commonly offered by dealers and collected by many enthusiasts, but I am surprised to find that little has been written about how do you really distinguish these three teeth from one another, especially when they are in small size - in this case I am refering to 1" and below size where the 3 of them look very similar to the untrained eyes. This is especially even more complicated when it comes to Deltadromeus agillis tooth which from what I gathered, shouldn't really technically be accepted to really exist, and should be ideally labeled loosely as Moroccan theropod, yet they are very common in the collectors market, but when asking how can you really tell if they are not Moroccan dromaeosaur tooth or simply a young Carcharodontosaurus tooth, nobody seem to be able to conclusively tell. The reason I am creating this post asking this question is because I just acquired a couple of new small Moroccan teeth that although have been labeled as Deltadromeus, but I can't be certain if they are really Dromaeosaur or young Carch teeth: Specimen A: Specimen B: Any theropod experts here could give insight into how to identify and differentiate these troublesome teeth would be appreciated and I think many new collectors and enthusiasts of Moroccan dinosauria would find such insights and knowledge very useful. Thx.

Here is my drawing of a Carcharodontosaurus tooth (3 different perspective) as it would have been if found fresh out of the mouth of that beast! The root is actually missing on my fossil, so it's very possible that the root would be different. I'm thinking to do the same thing for a bigger one, to do that I will need good picture of a big one, but I don't own such a tooth. Any opinion would be appreciated, additionnal observation would help to draw a better picture of these tooth and eventually it will help me draw the jaw when I will be confident enough Took about 25 minutes in total. I intend to do a more precise drawing eventually
