Fart o saurus reasponsible for prehistoric climate change!!!
So the latest bit of mind blowing marvelous science says that the dinosaurs had a massive effect on their climate from the amount of gas they passed!
What a funny and bizarre story, I am waiting for the environmental gestapo to jump on this one and insist we all pay for our anal emissions.A suggestion, this could be implemented with the idea of a rolling scale tailored to individuals, this scale would take into account your weight and diet, certain spicy foods and dishes would have and an extra charge added due to the increased level of flatulence they tend to produce in consumers.Those with irritable bowel would of course have to register their disability so to avoid being unfairly over taxed.
Certain animals and the keeping of these animals would be highly policed,where possible said animals would be kept in air tight tents in order to trap the gas that is emitted this is then processed for measurement and a tariff charged.
All joking aside this is an interesting read but in the grand scheme of things one can not help think that these guys may have just a little too much time on their hands.
The following article shows the research and findings, enjoy:
We might want to rename theBrachiosaurus with the monikerGassiosaurus, new research indicates. The gassy emissions from these giant dinosaurs may have been enough to warm the Earth, the researchers say.
Sauropods are large plant-eating dinosaurs typified by such titans as Apatosaurus(once known as Brontosaurus) and Brachiosaurus. When they lived, during the Mesozoic era — from about 250 million years ago until the dinosaurs died out 65 million years ago — the climate was warm and wet. Nothing on Earth today compares with these giants.
The researchers found that the greenhouse gas methane produced by all sauropods across the globe would have been about 520 million tons per year, a number on par with the total amount of methane currently produced by both natural and man-made sources. [Album: World’s Biggest Beasts]
The researchers, led by David Wilkinson of Liverpool John Moores University in the United Kingdom, did their best to get an accurate estimate of how much gas these big dinosaurs would have created, but their answers are still just estimates based on multiple assumptions, they warn.
The greenhouse gas methane is a natural byproduct of the digestive process of plant eaters, especially in herbivores called ruminants (like cows and camels). The researchers suspect that like ruminants, sauropods would have harbored methane-producing bacteria in their intestines to help digest these fibrous foods.
There is currently no way to tell what kind of bacteria lived in the digestive systems of dinosaurs, what gasses they produced, or what those digestive systems would have looked like, but Wilkinson thinks they would have produced methane like today’s animals.
“To process that amount of vegetation they have to be relying on microbes in their digestive system,” Wilkinson told LiveScience. “But without a time machine you can’t be sure.”
Crunching gassy numbers
They used a mathematical model to determine how much gas these plant-eating giants would have eaten. They extended data on methane production by modern mammals, based on size, up into the reaches of the sauropods.
In their calculations the researchers used middle-of-the-road numbers: 10 sauropods, each weighing 20,000 pounds (9,071 kilograms), could have roamed 1 square kilometer of lush Mesozoic habitats. “We’ve taken a middle-ground value,” Wilkinson said. “We tried to be reasonably conservative.”
They found that these 10 sauropods would have contributed 7.6 tons (6.9 tonnes) of methane every year. Expanding this number to cover the amount of land estimated to be hospitable habitat for these animals (about half the land on Earth at the time), the researchers end up with more than 550 million tons (500 million tonnes) of methane produced every year.
“I was expecting a number like that produced by cows, so the size of the number really surprised me,” Wilkinson said. “It’s way, way, way ahead of the estimated methane production by modern livestock.” (Cows produce 55 to 110 million tons (50 to 100 million tonnes) of methane each year, he estimated.)
It makes sense, based on the animal’s huge size, that they would make much more methane per individual than a cow. But, there are several other reasons why these large dinosaurs could have produced so much more gas than modern herbivores.
The animals would have had plenty of plants to eat, because they could reach high and low, and because of the warm climate, there was plenty of vegetation; in addition, these animals had much vaster areas in which to graze.
The real question is, did these dinosaur’s gassy emissions warm the planet?
“The thing about methane is it is an extremely potent greenhouse gas,” Wilkinson said. If the levels were anywhere near where their calculations indicate, he said, it very well could have been one of many factors that made that era warmer and wetter than modern times.
