That’s a Notorynchus sp.
@leyton-reid Thanks! Any way to determine the species?
@mason-m I’d be hesitant even on genus when we are missing the main conule. The deposits in that area are not very well known as far as I am aware so I’m not sure whether Notorynchus or Hexanchus is more common there. In the Miocene, Hexanchus is more common in the pacific and Notorynchus more common in the Atlantic.
