What evidence suggest that there was once a single super continent?

Evidence supporting the existence of a single supercontinent, known as Pangaea, includes the jigsaw-like fit of the continents along their Coastlines, similarities in rock formations and mountain ranges across different continents, matching plant and animal fossils found on separate continents, and the alignment of ancient glacial deposits that suggest a single ice cap covering a large landmass. These pieces of evidence support the theory of plate tectonics and continental drift.
