So there was a massive extinction event caused by coal 250million years ago - before the dino extinction 65 million years ago.
If coal comes from dinosaurs, where did the coal come from?
West Virginia and Pennsylvania mostly.

Contrary to what many people believe, fossil fuels are not the remains of dead dinosaurs. In fact, most of the fossil fuels we find today were formed millions of years before the first dinosaurs.

Coal formed from the dead remains of trees, ferns and other plants that lived 300 to 400 million years ago. In some areas, such as portions of what-is-now the eastern United States, coal was formed from swamps covered by sea water.
Coal is the remnants of decayed vegetative material not dinosaur.
If made past elementary school and did not know that you should have a serious talk with your school board.
During the Permian herbaceous matter, such as trees and other plants, would die and be buried under silt. The bacteria that eats such matter today did not yet exist then and this plant material eventually metamorphosed (due to extreme pressure and heat underground) into coal. That is why coal is referred to as a ‘fossil fuel’.
Dinosaurs have nothing to do with the formation of coal, natural gas, or petroleum.
