Mass whale grave found in Chilean desert.

There's also this cool "gosh-wow!" bit:

Researchers have also discovered fossils of other unusual creatures at the site, including a now-extinct dolphin that had two walrus-like tusks, an extinct aquatic sloth and an ancient seabird with a 17-foot wingspan. All in all, the site represents a remarkable snapshot of the ecosystem millions of years ago.
 

Dolphins with tusks!

An aquatic sloth!

Whodathunkthat!
