Detailed explanation-1: -Glossopteris fossils provide evidence that supercontinent Pangaea existed as the continents that made up Pangaea now have coal deposits that “match” the connected continents (like puzzle pieces fitting together). Glossopteris also provided paleobotanists information on plant life millions of years ago.
Detailed explanation-2: -The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones’ locations.
Detailed explanation-3: -During the first half of the 20th century, geologist Eduard Suess discovered that fossils of the extinct seed fern Glossopteris could be found on three different continents. This led him to believe that, at one time, the continents had formed one gigantic supercontinent, and later drifted apart.
Detailed explanation-4: -Fossils of Lystrosaurus are only found in Antarctica, India and South Africa.
