Dinosaurs are in for a makeover; new research suggests they were slimmer than we have been led to believe.
They have been traditionally portrayed as ground-shaking, thundering giants.
However, experts at the University of Manchester have created a formula that calculates the weight of the extinct creatures and found they were much more slender than earlier estimates.
The team used laser technology to calculate the amount of skin required to wrap around the average skeletons of modern living mammals.
They found that the total body mass of each animal was 21 percent more than the minimum volume of the 'skin and bone' wraps.
Their findings have been published in Biology Letters.
