'Dinosaurs killed off by their own flatulence'

Dinosaurs may have had been partly responsible for causing climate change as they emitted the potent global warming gas, methane, which could have been a factor for their own demise, say scientists.

Dinosaurs may have had been partly responsible for causing climate change as they emitted the potent global warming gas, methane, which could have been a factor for their own demise, say scientists.

A team at St Andrews University, Scotland, said the animals spent 150 years emitting methane. Large plant-eating sauropods would have been the culprits due to huge amounts of greens they consumed.

The scientists calculated the animals would have collectively produced more than 520 million tonnes of methane a year - more than all of today's 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, Daily Mail reported.

One of the animals, a 90-tonne argentinosaurus, which measured 140ft in length, would have consumed at least half a tonne of food in one day.

After breaking down in the animal's stomach, it would have produced thousands of kilos of the greenhouse gas.
