About 70 million years ago, an ostrich-like dinosaur brooding atop a nest of blue-green eggs met its doom, perishing with its nearly-hatched babies in what is now southern China.

Now, the remains of that beast — an oviraptorosaur, or a giant feathered dinosaur that walked on two legs — represent the only dinosaur fossil on record to be found sitting on top of eggs that still contain dinosaur embryos, a new study finds.
