First dinosaur eggs found ready to lay in mothher



The pelvis of an oviraptor includes two eggs with shells in place, almost ready 
to lay, showing that theropods had two working oviducts, in contrast to the one 
of birds. It also shows that dinosaurs laid pairs of eggs in a series of 
sittings to make a whole clutch, not a whole batch at once. The paper is in the 
just-out Science; the story with photos is at

It's a really impressive fossil.
