An unusual find in China suggests some early mammals may have hunted dinosaur for dinner.

The fossil shows a badgerlike creature chomping down on a small, beaked dinosaur, their skeletons intertwined. The find comes from a site known as "China's Pompeii," where mud and debris from long-ago volcanoes buried creatures in their tracks.

The fossil of a 170-million-year-old pterosaur, described as the world's best-preserved skeleton of the prehistoric winged reptile, has been found on the Isle of Skye in Scotland, scientists said on Feb. 22.

Chinese construction workers excavating bedrock recently made an explosive discovery when they inadvertently unearthed an unusual new species of feathered dinosaur. The animal lived about 66 to 72 million years ago, right before a giant impact wiped out large dinosaurs in a catastrophic mass extinction.
