Archaeocete Molar

This is one of the molars from Jedi Master's mega oligocene toothed whale. I've found a few of these in the Edisto, and even though it looks like an eocene archeocete, I've been calling these archeomysticetes since so little is known about the oligocene variety. He says he thinks its still archeocete in the oligocene, though it is very likely the end of an evolutionary line.
