World's most complete Stegosaurus dinosaur

The world's most complete specimen of a Stegosaurus dinosaur dating back to 150 million years weighed 1,600kg, equivalent to a small rhino, researchers have found.The researchers from Imperial College London and the Natural History Museum calculated the body mass of the extinct creature to get an accurate measurement.They used this approach on a Stegosaurus skeleton nicknamed Sophie, which was found in Wyoming in the US in 2003. They have calculated that Sophie would have weighedaround 1,600 kg, similar in weight to a small rhino."Although the Stegosaurus is something of an iconicdinosaur, scientists know very little about its biologybecause its fossils are surprisingly rare," Dr Susannah Maidment, Junior Research Fellow from the Department of EarthScience and Engineering at Imperial College London, said.
