How many years ago waspangea?

Pangaea, the supercontinent that existed during the late Paleozoic and early Mesozoic eras, began to break apart about 175 million years ago. It formed approximately 335 million years ago, so it was fully assembled around 335 million years ago and started to break apart around 175 million years ago. Thus, Pangaea existed as a unified landmass for roughly 160 million years before its fragmentation.
