How can lystrosaurus fossils be found on all continents if it cant swim?

Lystrosaurus fossils have been found on all continents due to the phenomenon of continental drift. During the time Lystrosaurus lived, around 250 million years ago, the continents were joined together in the supercontinent Pangaea, allowing these land-dwelling creatures to inhabit a continuous landmass. As the continents drifted apart over millions of years, the fossils remained, leading to their discovery in various locations today. This illustrates the historical continuity of land-based species before the separation of continents.
