A shark tooth found on Caspersen/Venice Beach back in 2010. Anyone know what it is?

Isurus retroflexus.

Why not Carcharodon (Isurus) hastalis ?

Coco

I see a mesio-distal depression in the labial face of the root adjacent to the base of the crown and an enamel band on the shoulders of the root. Which would point toward retroflexus rather than hastalis.
