Caption: Princeton geoscientist Gerta Keller and a research team have compiled new evidence disproving a popular theory that an asteroid wiped out the dinosaurs about 65 million years ago. Examinations at several new sites have produced biotic evidence -- the fossilized traces of plants and animals -- indicating that a massive die-off did not occur directly after a proposed asteroid strike but much later.
