A paleontologist discovered many Lystrosaurus fossils in South America, Africa, India, and Antarctica. These fossils are found nowhere else on Earth. Based on the species anatomy and rock layer depth, the paleontologist concluded that the now-extinct Lystrosaurus species was a large land reptile that lived during the Mesozoic Era. What can be inferred from this fossil evidence?
Millions of years ago, South America, Africa, India, and Antarctica were once joined together in a much larger landmass.
