Overview

• Footprints date back 120 million years to the Early Cretaceous period.
• Most prints were made by three-toed theropod dinosaurs, with some by sauropods and ornithischians.
• The footprints were found in ancient river and lake sediments, now 3,700 miles apart.
• The discovery supports the theory of a land bridge between South America and Africa before continental drift.
• Researchers published their findings in a study by the New Mexico Museum of Natural History & Science.
