Dinonsaurs Were Headed For Extinction Before Asteroid Hit Earth

A new study of dinosaur eggs from the time of their mass extinction reveals the species was already on the way out before an asteroid struck.

Researchers who examined more than 1,000 fossilized dinosaur eggs and eggshells found dinosaur diversity was declining when the asteroid smashed into the earth 66 million years ago.
