I’m not seeing where it says specifically says that the tracks were made by the same individual dinosaurs, rather than by the same types of dinosaurs. The footprints found in Brazil and Cameroon are described as being “almost identical” in shape, and they are attributed to similar species, such as theropods, sauropods, or ornithischians.
The focus of the article is on the matching footprints being evidence that land-dwelling dinosaurs of similar species could move across the continents before they split, rather than suggesting they were left by the exact same individual dinosaurs.
Or is there a different article that is about these same footprints that says they are the same individuals?
