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.

Shown is a recreation of Squalicorax, one of the 18 new species identified from the 100- to 72-million-year-old rocks.
