The Misa Sauris was a dinosaur that existed millions years ago. The fossil in the Mesa sores have been found on both the east coast, and South America and the west coast of Africa is seen on the image. What is the best explanation for this?

The best explanation for the presence of Misa sauris fossils on both the east coast of South America and the west coast of Africa is the theory of continental drift. Continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea and have since drifted apart over millions of years. According to this theory, Misa sauris inhabited Pangaea, and as the continents separated, their fossils got preserved in the separate landmasses that they ended up on. The geological and paleontological evidence supports the theory of continental drift, explaining the distribution of fossils across different continents.
