Fossil Distribution

During the time that the supercontinent Pangea existed, the same type of plants and animals would have been distributed throughout the landmass. Today, these plants and animals have been extinct, leaving behind their fossils and some evolved species. These fossils records show how they were distibuted.
An example to support the theory of continental drift are the fossils of Lystrosaurus. This sheep-sized reptile existed 200 mya and its fossils are found on the continents of South Africa, India and Antarctica. These creatures couldn't have evolved on these continents alone nor could they have crossed the oceans, meaning that the continents whould of had to be joined in the past.
