Shark Teeth Id's For Christmas

Extinct ground shark or extinct requiem shark would be correct, although still pretty vague.

So these are now requim not tigers? hm.

To be technical, Tiger sharks are a type of requiem shark, as are Bulls, Duskys, Lemons, Blues etc. Physogaleus just hasn't been given a common name (that I know of)

Thanks, I did not realize that. So are there any other types of Physogaleous or just contortus?

There is also (from North America) P.secundus and P. rosehillensis from the Eocene (although the latter species is iffy as to it's affinities) P.latus is from the Oligocene and P.contortus was the end of the line. There are other species from other parts of the world as well.

Thanks again for all the insite.
