Identify the mystery animal!

Tammie, Rosa and I went down to the loch to feed the ducks with Roger and Hunter. While walking around on the muddy shore, we found a jawbone full of very odd teeth. None of us can figure out what animal it was.

We also found most of the skeleton of a large fish--rib bones nearly six inches long. The suggestion was made (and it seems likely) that it's actually someone's grilled salmon dinner, thrown off the deck into the lake at some point in the past.
