"By: Stephanie Pappas, LiveScience Senior Writer Published: 04/10/2013 01:04 PM EDT on LiveScience Embryonic dinosaurs kicked and wiggled in the egg, a new discovery of a baby-dino-bone bed suggests. The bones, all from not-yet-hatched embryonic dinosaurs, are among the oldest dinosaur-embryo fossils ever found. What's more, the embryo fossils came from separate nests and the dino embryos were at different stages of development when they died — two discoveries that will enable researchers to study how dinosaurs developed before hatching. "It tells us quite a bit about early embryonic stages and changes that occur in the embryonic life of these animals — something we haven't really seen before," said study researcher Robert Reisz, a paleontologist at the University of Toronto."
