Dinosaur Gases Warmed the Earth
Giant dinosaurs could have warmed the planet with their flatulence, researchers said. British scientists have calculated the methane output of sauropods, including the species known as Brontosaurus. By scaling up the digestive wind of cows, they estimate that the population of dinosaurs – as a whole – produced 520 million tonnes of gas annually. The researchers, who published their results in the journal Current Biology, suggest the gas could have been a key factor in the warm climate 150 million years ago.
