Hi, This question is between categories. Has anyone seen markings (numbers) on a shark tooth like this? I have tried to wipe them off with acetone, and they will not come off. Any idea how they were applied or how to remove them?

In my attempt to self educate myself, I am tring to find as much information on the Texas Cretaceous fossils I find. I am a bit confused about the scientific notation of genus species. For example, in much of the literature, there will be a name in parenthesis : like Pecten (Neithia) texanus or Trochus (Tectus) texana. (examples from the Studies of Some Comanchean Pelecypod paper). And in the Field Guide to Fossils of Texas, Mesalia (Turritella) seriatim-granulata and Gyrodes (Sohlella) spillmani. What does that mean? Is Pecten the proper name or Neithia? Is it Mesalia or Turritalla? Or is it both? Or if there is a question mark after the genus - like Cerithium? barionnenne or Pseudomelania ? pupoides (Both examples from the Studies of Some Comanchean Pelecypod paper). Are they just not sure if that is the proper Genus and leaving it open to interpretation and further study? Any help is appreciated!
