Quizplus · Accepted Answer

Petroleum is primarily formed from marine plankton that died and sank to the bottom of the ocean millions of years ago. Over time, layers of sediment and rock covered the dead plankton, subjecting it to high pressure and temperature, transforming it into petroleum. While some coal may have contributed to petroleum formation, it is not the primary source. Dinosaurs were not the source of petroleum, although some petroleum may have formed from the remains of ancient reptiles and other organisms. Peat bogs are the precursor to coal, not petroleum.
