Can anyone identify this jawbone?

Found in Tasmania , any help appreciated. I can't think of any animal native let alone foreign.
Tusk or why is very sharp almost arrowhead like.

Any help appreciated.

It's a Bennett's kangaroo lower mandible.
Wow.

How did you find THAT ?

...or is the anatomy of the Tasmanian tree Kangaroo a bit of a hobby ?
the Animal Planet network.
I saw a documentary on Australian/Tasmanian marsupials a couple of years ago and remembered it making mention of the unusual dentition of the Bennett's kangaroo. A quick Google image search found a nice diagram of the mandible. :)

I am in Melbourne and just found this in my compost bin,(hence the dark colour) so I put it in, which means its either a rat or a ringtail possum. We thought possum but came searching the web to ID it. Not identical but pretty close. This one is the same size but with more of a curve to it. Wow never knew those sweet little possums had tusks!!!

The Natural History Museum has dedicated identification forums. You have to register, but it's free, and you'll be able to upload the photo to the "teeth and skulls" forum.

Some kind of pig is my guess.

It ain't a whale or seal, and its not a Tasmanian Devil - my first guess ;-)
So that shortens the list a bit
