A study conducted by the journal Current Biology suggests that dinosaur flatulence may have been a source of global warming.

The study conducted by David Wilkinson from Liverpool John Moores University and his colleagues from other various UK Universities suggested that Saurapods, a herbivorous species of dinosaurs, produced 520 million tons of greenhouse gas methane per year. Cows (50-100 million tons) and man-made sources (500 million tons) produce less methane than those extinct species.
The research found that the weight of these dinosaurs are correlated to the amount of methane produced.
Dinosaurs might have farted their way to disappearance, since many believe that global warming is a reason behind their extinction. According to BBC News, the study conducted by Current Biology states that the flatulences might have been the reason why the planet was about 10C (18F) warmer than it is today.
