This is some of the worst science reporting I've seen in a long-ass time. They describe the skull as being 3m long, which would make the 'prey' whale in the picture about 5m. That's the size of a Beluga whale, not a baleen whale like the one in the picture. Which means that the picture is a load of bunk, making you think leviathan is some big momma, instead of being about the size of a bus and a half. Then they go on to talk about the behavior of the dead whale - behavior doesn't fossilize. They're talking out their asses. Plus some of the inanities at the end are infuriating. They're all whale experts? What a shocker, whale experts publishing a paper about whales. I would have thought for sure they'd be economists, not whale experts.
But what really gets me is that they stole the name Leviathan. In ten years, when we discover something really awesome, that totally deserves the name, and they won't be able to use it, because it was taken.
