It has long been known that cows are a major source of emissions of pollutants, particularly methane. Cows, sheep and other ruminants are estimated to be responsible for one-fifth of global methane production — a greenhouse gas linked to climate change.
Scientists used cow farts to estimate the amount of gas produced by dinosaurs at 520 million tons a year. Perhaps the creationists are right and man did walk with the dinosaurs. If so, those primitive cave pictures might have been efforts to design the world’s largest air freshener.
The most gaseous were likely sauropods who fed on vegetation in the Mesozoic Era like the Brontosaurus. Studies indicate that the Earth was up to 10°C (18°F) warmer in the Mesozoic Era and apparently a lot smellier.
