The BBC reports Whale fossil sports fierce teeth:
Palaeontologists have discovered a bizarre whale fossil in Australia with a set of fearsome teeth.
The specimen has surprised scientists because it belongs to the group known as baleen whales.
Modern day baleen whales are all placid, plankton eaters, but the new fossil shows the group were not always the ocean's gentle giants.
Details of the 25 million-year-old find appear in the journal Proceedings of the Royal Society B.
You need to subscribe to get the full article from Proceedings of the Royal Society B but the abstract is here.
Another piece to slot in the story of whale evolution - I don't know if it is really of any significance or not at this point in time.

Fascinating discovery! Thanks for sharing the news.
It will be interesting to see where this critter fits in the family.

That's really interesting, thanks for posting it. I would imagine there was a time when baleen whales could both eat with teeth and filter feed. I wonder why they eventually moved to feeding solely on krill and plankton.
