Dinosaur flatulence warmed the earth

Published 07/05/2012

The flatulence emitted by dinosaurs during their reign on earth could have warmed the planet, scientists have suggested.

Researchers have calculated the methane output of sauropods, including the species known as Brontosaurus, and believe it could have been up to as much as 520 million tonnes of gas annually.

Comparing dinosaurs’ flatulent output to the digestive wind of cows, they believe the gas could have been a key factor in the warm climate 150 million years ago.

David Wilkinson from Liverpool John Moore's University told the BBC: "Although it's the dinosaur element that captures the popular imagination with this work, actually it is the microbes living in the dinosaurs' guts that are making the methane."
