So does this just prove the same species existed between the two or are these actually like from the same dinosaur, at the same time, and then got separated

I'm assuming the same species. But if it was the same dino at same time, that'd be badass! But I just don't think that would be possible to know.

Actually it was the same Apatosaurus, Triceratops, Saurolophus, Pteranodon, and Stegosaurus tracks on both sides. They led into this hard to find valley.

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?

Pretty sure they're just making a Land Before Time reference, not a serious claim (did those species even live during the same time periods in real life?)
