About 120 million years ago, dinosaurs walked across the supercontinent Gondwana, leaving behind 260 footprints.
Millions of years ago, a supercontinent known as Gondwana ruled the Earth. This allowed dinosaurs to roam freely between the two continents: Africa and South America.
Back then, Gondwana was a piece of the larger landmass Pangea. “We determined that in terms of age, these footprints were similar. In their geological and plate tectonic contexts, they were also similar. In terms of their shapes, they are almost identical,” said Louis L. Jacobs, SMU paleontologist. The dinosaur tracks were discovered in the Borborema region of northeastern Brazil and the Koum Basin of northern Cameroon. These provide irrefutable evidence of the land bridge that once connected the two continents.
While most fossilized footprints were left by theropod individuals with three toes, some may have been made by sauropods or ornithischians.behavior, from dinosaur species to how fast they could run. These fossilized dinosaur tracks may allow researchers to reconstruct the lives and environments of these fascinating creatures.As Gondwana began to break apart, the massive land bridge between Africa and South America slowly disappeared around 140 million years ago.
