(Daily Mail) — 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 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.
One of the animals, a 90-ton argentinosaurus, which measured 140ft in length, would have consumed at least half a ton of food in one day.
After breaking down in the animal’s stomach it would have produced thousands of litres of the greenhouse gas compared with a modern cow which only produces 200 litres of methane daily.
Methane is up to 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2).
It is created from a variety of natural and human-influenced sources which include landfills, natural gas, petroleum sources and agricultural activities.
Scientists claim humans have pushed levels of the gas up 2.5 times higher than they should be and estimate this is responsible for 20 per cent of modern global warming.
Cows and other livestock currently only emit about 100m tons of methane a year.
According to Professor Ruxton and his co-researcher David Wilkinson, of Liverpool John Moores University, this is only a fifth of what was produced when Dinosaurs walked the Earth.
‘In fact, our calculations suggest these dinosaurs may have produced more methane than all the modern sources, natural and human, put together,’ said Mr Wilkinson to the Sunday Times.
Yep! It is now official, EVERYTHING, except Al Gore of course, did cause, will cause, or is causing global warming, climate change, global cooling, or whatever they are calling it this week!

I wonder how they’re getting that number for the methane produced.
Are they using cows and just multiplying the gasses by a certain multiple to get weight equivalents?
Because reptile biology and mammal biology are different in how they process food.
Cows fart all the time because that’s how their stomachs operate.
I don’t know about huge lizards, but I do have an iguana who has been eating the right food (collard and mustard greens) since she was rescued, and the only time she out-gasses is when she goes poop- and that’s a just a bubble in the water and done.
That’s because the iguana hind-gut has the needed bacteria to break down vegetation instead of digesting, like mammals do.
So, It’s just natures way of controlling evolution then… that we kill ourselves off with our own flatulence (or in our case with our own comforts of life). Then maybe we shouldn’t feel so bad, as long as the dolphins survive.
