Hey all,
I have a tooth here, and I'm a bit confused. It comes from Hoevenen (BE), and dates from the Miocene. I'm pretty sure that it's a mako tooth, but I'm not sure what species: Isurus hastalis or Isurus oxirhynchus? Or perhaps another one? Also, how exactly can you distinguish I. hastalis from I. oxirhynchus?
Best regards and have a nice Sunday!
Max
