When did Pangaea begin to split apart?

Pangaea, the supercontinent that existed during the late Paleozoic and early Mesozoic eras, began to split apart approximately 200 to 225 million years ago. This period marks the transition into the Mesozoic Era, particularly during the Triassic to Jurassic transition. As the tectonic plates shifted, Pangaea fractured into smaller continents, initiating the continental drift that ultimately shaped the Earth's current geographical layout.

The timing aligns with significant geological events, such as the formation of rift valleys and the movement of tectonic plates that led to the opening of oceanic basins. This pivotal moment in Earth's history served as a critical juncture in continental and oceanic formation as we know it today. Understanding this timeframe is crucial, as it illustrates the dynamic nature of the Earth's lithosphere and its impact on biodiversity and climate over millions of years.
