The #1 thing wrong with the report is that Triceratops was herbivorous, so eating part of a Pterodactyl wouldn’t have been of interest.The #2 thing wrong is that gas tank contents mostly came from vegetative matter, not dinosaurs. Dinos would make lousy motor fuels, which need to start with mostly carbon and hydrogen. Vegetative matter also has sulfur, which can be removed in refining, and nitrogen which mostly escapes during the compression-and-breakdown process. Dinos contained sulfur and nitrogen, plus calcium, phosphorus and smaller amounts of other elements, all of which don’t belong in gasoline.
Powdered foodstuffs most certainly can go bad. Carbohydrates and proteins are readily attacked by bacteria, and sometimes by fungi. And oils/fats will oxidize and/or go rancid if exposed to air. Of course, in all cases, anti-bacterials, anti-oxidants and the like can be added. But you shouldn’t assume that a powdered foodstuff that’s old is OK unless you know it’s protected from deterioration.
Lima beans are wonderful.
