Scientists discovered over 260 dinosaur footprints in Brazil and Cameroon, regions now separated by the Atlantic Ocean but once part of the supercontinent Gondwana. The tracks, dating back to the Early Cretaceous Period, are nearly identical in age, shape, and geological context, suggesting that dinosaurs roamed freely between these areas about 120 million years ago. Most of the tracks were made by three-toed theropods, with some from sauropods and ornithischians. This discovery provides strong evidence of the ancient land bridge that connected Africa and South America before the continents drifted apart around 140 million years ago. The study, led by paleontologist Louis L. Jacobs, offers valuable insights into dinosaur behavior and the conditions of prehistoric Earth.
