The world received a super gross-out this week when a 15-ton block of congealed fat that has been dubbed "Fatberg" was pulled out of a sewer beneath London. The unsightly blob of lard exists thanks to Londoners dumping fat from food down their drains.

An extremely well-preserved, rodentlike fossil -- Megaconus mammaliaformis -- recently discovered in China provides some of the best evidence yet for how our earliest ancestors lived.

According to a paper in the "Journal of Systematic Paleontology," waters off the coast of France and the U.K. were once teeming with sharks. Samples of Late Cretaceous rock from the region revealed the remains of 96 different types of prehistoric shark, 18 of which represented new species. Shown is a recreation of Squalicorax, one of the 18 new species identified from the 100- to 72-million-year-old rocks.
