Is this actually a widespread belief held by adults? I think the first time I came across it expressed was in Airplane II - “Well, let's see: First, the Earth cooled. And then the dinosaurs came, but they got too big and fat, so they all died and they turned into oil.” - where, like, the naïveté of the statement is the joke, right?

So then when Pixar movies have an oil company called ‘Dinoco’ in them, I’d always assumed that’s as part of that same kind of knowing ‘obviously only a child believes oil comes from dinosaurs’ reference.

The idea that oil could be made from dinosaurs is just.. on its face, it’s not plausible, right? It can’t be something people are actually taught. Please.
