2.4 inch Otodus aksuaticus shark tooth from the Eocene Nanjemoy Formation of Maryland. This is a good example of the transition from obliquus to auriculatus, with serrations extending about halfway down the crown.-

I'm finally getting around to posting pictures of this Moroccan shark tooth, which I believe is either a transitional Otodus obliquus or a transitional Palaeocarcharodon orientalis. My original thought was Otodus but @Al Dente flagged in the mailbox thread a few weeks ago that it might be Palaeocarcharodon instead. Any thoughts on this one? The tooth measures 49 mm on the slant and is 39 mm wide across the root.

Recently I aquired this Carcharodon tooth from Sacaco, Peru whose serrate conditions seems a bit peculiar to me. I can't really decide whether or not this tooth is from a late-stage hubbelli or an early carcharias. The serrations seem to wear/taper off just short of the tip on one side and abruptly end near it on another, and some (although not all) of the serrations appears to be angled in a way, although I suspect some may be due to wear. My thoughts on the serrations keep seesawing in my head. Would this tooth better represent a late-stage hubbelli or a carcharias? Thanks for any and all answers. Lingual
