I THINK petroleum
You're thinking on the right track, but in reverse. Petroleum is a product made from crude oil, not the other way around. Crude oil is made from extinct biomass, that is plants and animals that lived millions of years ago, subjected to underground pressure over a long period of time until the oil is all that is left of them.
Oil is commonly formed in rock or in sealed pockets under the seabed and it is from the Latin for 'rock oil' that the word 'Petroleum' is derived

Oil cakes are formed from remains of oil seeds after the extraction of oil by oil mills.
Crude oil is made from prehistoric decomposed plants formed millions of years ago, it is extracted using an oil rig. :)

Crude oil, coal and are fossil fuels. They were formed over millions of years. Crude oil and gas were formed from dead marine organisms

Scientists don't just believe, they know coal is formed from ancient plants compressed in anaerobic environments. However, nobody with a knowledge of geology or paleontology believes oil is formed from dinosaurs. Oil is primarily formed from plankton and algae.
Oil sands are formed from a mixture of sand, water, clay, and bitumen - a heavy oil. Over millions of years, organic material decays and the bitumen collects in sand and silt deposits, creating oil sands. Heat and pressure further transform the bitumen into crude oil.
