I’ll be that guy - fun facts time!

Coal comes from the carboniferous period and is really just anoxic transformation of layers and layers of old peat bog covered by sedimentation and transformed by heat, pressure and geologic time ~ 300 Ma.

Oil and gas come from the mesozoic era which was the time of the dinosaura clade, but the carbon in the oil comes from marine deposits of phyto and zooplanktons. - 252-65 Ma.

No actual dinos in fossil fuel. Weird I know. I also know you likely didn’t care to hear any of this, but like I said, I’m that guy.
