Lee Creek NC spoils pile find. I suspect it is a juvenile C. megalodon upper-posterior, but the asymmetry is throwing me off. Am I on the right track or way off?

I acquired these megs years ago, probably from a rock and fossil shop in Texas, USA. Is it at all possible to speculate where they might have originally been found based on their coloration and condition? Also, they have been "preserved" with what looks like clear lacquer. Is there a way to remove this without damaging the teeth? I would like to return them to somewhat of an "as found" condition. I realize they are poor quality specimens and not very large, but the shiny coating is bugging me!

I'm preparing to put these teeth up into a plaque to showcase the evolution of C. megalodon (a much disputed topic in and of itself). I just acquired the second to left tooth from a dealer in Florida who claims the tooth is a C. auriculatus and the middle tooth was from another dealer who claims it's a C. angustiden. I realize that size in this scenario doesn't matter and I should pay more attention to the serrations and defined cusps but I'm beginning to wonder if the middle tooth is a C. auriculatus because of the increased number of serrations and more defined cusps and the one to it's left could be a C. angustiden. I'm considering swapping them for the display but I'm not sure if that would be accurate. I've read a number of articles that argue that the C. angustiden and C. auriculatus where just a large O. obliquus. That's another debate. Should these all be classified under Otodus rather than Carcharocles? I'm leaning towards Otodus because from an evolutionary stance that would make for sense. The teeth on the right side (left to right) are C. chubutensis and C. megalodon both from Calvert Cliffs, MD. What are your thoughts on this subject?

Pretty sure this is a weathered C. megalodon tooth.
