I assume Blake's suggestion of crocodile was intended to be humerus,
however, the tooth sockets do suggest peg-like teeth, similar to reptiles.
The size of the animal should suggest "whale" to most people, and given
that there are tooth sockets, it is then, by definition, a toothed whale.
All of our toothed whales (which I've seen anyway), have peg-like
teeth...they have re-acquired this from a terrestrial ancestor which had
the mixed bag of teeth characteristic of mammals.

So, which toothed whale? The snout isn't pointy enough to be a pilot whale
(I just ran to the lab to confirm this), and the overall length of the
animal suggests to me something a bit bigger. I estimated the length of the
animal at over 6 m, using the man's height as 1.7 m (an estimate);
Wikipaedia says the males (the larger of the sexes) reach sexual maturity
at 4.6 m, but don't give an upper size range.

That's as far as I can take it. The marine environment is not one of my
fortes.
