World's Oldest Footprints Discovered on Ancient Seafloor

Neil Armstrong left the first footprint on the moon, on July 20, 1969. But what about Earth — when did animals first leave footprints here?

While we don't know exactly when animals first left tracks on our planet, the oldest footprints ever found were left between 551 million and 541 million years ago during the Ediacaran period, a new study finds. That's hundreds of millions of years before dinosaurs started roaming Earth, about 245 million years ago. The new findings suggest animals evolved primitive "arms" and "legs" earlier than previously thought.
