During periods of extreme global warming, which were mass
extinction events both 90 and 150 million years ago, the oceans
became stagnent, and most marine organisms died, sunk to the bottom
and were buried by sediment.
Oil was formed from the remains of animals and plants (diatoms) that lived millions of years ago in a marine (water) environment before the dinosaurs. Over millions of years, the remains of these animals and plants were covered by layers of sand and silt. Heat and pressure from these layers helped the remains turn into what we today call crude oil. The word "petroleum" means "rock oil" or "oil from the earth"
