Kerogen Type Primary Source Primary Fossil Fuel I Algae Oil II Plankton, Bacteria, Algae Oil and Gas III Land Plants Gas and Coal Modern Evidence and Extraction We know the biological origin of oil not just from theory, but from direct observation. The question of whether oil came from dinosaurs is one of the most persistent myths in modern geology.
Marine Life: The Primary Source of Crude Oil
When these organisms died, they sank to the bottom of shallow seas and oceans, accumulating in thick layers of sediment on the sea floor. These chemical fingerprints confirm that the source material was once living marine life.
Instead, it is subjected to intense heat and pressure over millions of years. Why the Dinosaur Myth Persists The association between oil and dinosaurs likely stems from the visual imagery used in advertising and popular culture.
From Marine Life to Crude Oil: How Plankton and Algae Became Oil
This process breaks down the complex organic molecules into the simpler hydrocarbon chains that make up crude oil and natural gas. Type III kerogen is primarily from land-based plant matter and is more likely to produce natural gas or coal than liquid oil.
