Paleontologists have discovered two new species of mammal-like, burrowing animals that lived about 120 million years ago in what is now northeastern China. The new species, described today in the journal Nature, are distantly related but independently evolved traits to support their digging lifestyle. They represent the first "scratch-diggers" discovered in this ecosystem.
