"Dinosaur gases warmed the Earth"
Giant dinosaurs could have warmed the planet with their flatulence, say researchers.
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.
They suggest the gas could have been a key factor in the warm climate 150 million years ago.
David Wilkinson from Liverpool John Moore’s University, and colleagues from the University of London and the University of Glasgow published their results in the journal Current Biology.
