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?

I have been seeing Delta teeth floating around the net lately and was wondering how you teeth experts can tell the difference or unique features that separate one from another since most of them to my eyes, they look almost the same. With Delta teeth of size smaller than 1.5" I can kinda see it tend to be flat and blade-like like Dromaeosaur's teeth and you probably may be more likely to get them confused with Raptor's teeth more so than Carch teeth which from my observation, the smaller teeth seem to look bulkier and a little stout in shape. However when it comes to Delta teeth of 2" and bigger I see very little difference from a Carch tooth of similar size so how do you tell the difference? And correct me if I am wrong, but it seems like a Delta teeth of 2" and above seem to be a rarity from my experience but in reality are Delta teeth more costly than a Carch tooth of comparable size and quality? Since it seems to be a rarer specimen I would assume the answer should be yes, but I can't be sure.
