Dinosaurs may be partly to blame for a change in climate because they created so much flatulence, according to leading scientists.
Professor Graeme Ruxton of St Andrews University, Scotland, said the giant animals spent 150 years emitting the potent global warming gas, methane.
Large plant-eating sauropods would have been the main culprits because of the huge amounts of greenery they consumed.
The team calculated the animals would have collectively produced more than 520m tons of methane a year more than all todays modern sources put together.
It is thought these huge amounts could easily have been enough to warm the planet.
It is even possible that the climate change was so catastrophic that it caused the dinosaurs eventual demise.
Unless they want to postulate that the effects of the impact were worsened by that methane or that the planet was struck by a fart-sniffing meteor attracted by the methane then the entire theory fails.
But when you are an acolyte of the Cult of Global Warming, everything proves your pet theory.
