If only I was willing to waste my time “researching” fossil fuels and the Mesozoic era to then anoint myself an expert in the field that’s do ‘doing my own research’. If only I was arrogant to think that these are such simple questions.

At what depths, and locations, are all types of fossil fuels found around the world?

What are all the locations and depths of dinosaur life that died ?

Calculate probability that, on some reasonable level, these remains formed hydrocarbon materials potentially used as fuel?

Super simple.
