What evidence from rocks shows that India and South America and Africa were part of a single landmass located near the south pole about 280 million years ago?

Evidence from geological formations, fossil records, and paleoclimate indicators supports the theory that India, South America, and Africa were part of a single landmass, known as Gondwana, near the South Pole about 280 million years ago. Similar rock types and ages found across these continents, such as coal deposits and glacial till, indicate they were once connected. Additionally, identical fossil species, like the plant Glossopteris, have been discovered on all three continents, suggesting they were part of a contiguous ecosystem. This geological and paleontological evidence points to the existence of a supercontinent before continental drift separated them.
