All of them.Has anyone ever thought about it? With all the oil in the earth did it all come from dinosaurs? If so how many did it take to produce all of our oil?
You beat me to it, LOL!All of them.
Our oil formed from the remains of marine plants and animals that lived millions of years ago.
Oil comes from solar energy. Plants are a very efficient solar panel.
Animals eat plants. And each other...
Add a couple of millions of years to the process and you can fill 'er up!

I was led to believe that coal was plant based and crude oil was from single celled sea organisms/plankton and algae.
Wikipedia said:Upon heating, kerogen converts in part to liquid and gaseous hydrocarbons. Petroleum and natural gas form from kerogen.[1] Kerogen may be classified by its origin: lacustrine (e.g., algal), marine (e.g., planktonic), and terrestrial (e.g., pollen and spores).
Dinos couldn't take the "high temp, high shear" of that comet/asteroid ramming into the Earth.If dinosaur oil were synthetic and thicker, they would still be alive & running!

The problem is that we use the oil up exponentially faster then the Earth and make it.The earth produces and reproduces crude petroleum. It is the ultimate renewable resource.
