Dinosaurs lighter than previously thought

Dinosaurs are often portrayed as heavy, lumbering beasts - now it seems that this wasn't the case.

A team at the University of Manchester have used laser technology to perform new calculations on the body mass of dinosaurs, what they found was that many species of dinosaur would have weighed far less than you would expect. The colossal Brachiosaurus for example which was estimated to weigh up to 80 tons was more likely to weigh around 23 tons.

"Our method provides a much more accurate measure and shows dinosaurs, while still huge, are not as big as previously thought," said Dr Bill Sellers.

"The enormous animals are traditionally portrayed as monstrously heavy, with thundering footsteps and a huge bulk adding to their fearsome appearance."

Not a well reported article and using mammals to compare to dinosaurs seems strange, surely reptiles would be a better choice.

Chickens would have been a better comparison I think

Eggs would be a better comparison.

Producing a formula to accurately calculate the animalís dimensions, they found a Brachiosaur, estimated to be as heavy as 80 tons, would actually have weighed a relatively light 23 tons Not much of a difference there if you just happen to get stepped on by one of them.

The Chinese were right all along...they were dragons....not our modern quasi-scientific falsely labeled Dinosaurs!

Once again science has to correct itself. Makes one wonder what other things science is wrong about.

actually, dinosaurs are believed to have been warm blooded. Not mammals but warm blooded like birds. Reptiles came before dinosaurs during the late Carboniferous period. At that time it was so hot animals would have no need to produce their own body heat, blah blah blah... That being said, no one really knows whether or not Dinosaurs were warm or cold blooded. Either way they were definitely NOT reptiles, not to mention, the only animals alive today big enough to compare bone to flesh ratios on a large scale are in fact MAMMALS. So, in short; your're dumb.

I've always remembered the 80 ton estimate for big Brachiosaurus that's been around for years. 23 tons sounds a lot more reasonable.
