Transitional Otodus or Palaeocarcharodon

Recommended Posts

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.

Otodus.  The flat, squared-off root lobes and the "pushed in" appearance of the indentation are indicators.

Seems too flat to be Otodus. I'd be in the Palaeocarcharodon camp on this one.

Thanks, @hemipristis, that one definitely shares some similarities with mine. Do you know if the tooth in the picture is also from Morocco?
