Sixty-five million years ago, a giant asteroid collided with Earth. But were dinosaurs around when it hit?
A team of Yale scientists led by Tyler Lyson GRD ’12 and Stephen Chester GRD ’12 discovered a fossil last year that provides evidences for the well-known hypothesis that an asteroid wiped out the dinosaurs. They found the fossil only 13 centimeters below the layer of rock that indicates a massive impact 65 million years ago, a discovery that they said proves dinosaurs were thriving before an asteroid hit earth then.
