Museums and TV have dinosaurs' posture all wrong, claim scientists
Research suggests the largest dinosaurs, the sauropods, did not stick their necks out in front of them but held their heads high

The staid and scholarly world of palaeontology was thrown into rare turmoil yesterday following the latest salvo in an argument that dates back to Jurassic times.
The row erupted after a team of British fossil experts published a fresh analysis of animal bones in an arcane academic journal. In their paper they challenge a view of dinosaurs that is so familiar it has almost become the accepted truth.
The controversy goes to the heart of our perception of the largest of the dinosaurs, the sauropods, which became widespread 150m years ago in the late Jurassic. According to the researchers, the beasts did not stick their necks out in front of them as so often depicted, but held their heads high on majestic, curving, swan-like necks.
The claim overturns the popular impression of the lumbering creatures given by museum exhibits and TV series like the BBC's Walking with Dinosaurs. The sauropods include many of the most well known prehistoric beasts, such as diplodocus and apatosaurus, the dinosaur formerly known as brontosaurus. Some sauropods were more than 40m long and weighed over 100 tonnes.
"Unless sauropods carried their heads and necks differently from every living vertebrate, we have to assume that the base of their neck was curved strongly upwards," said Mike Taylor, a palaeontologist at Portsmouth University in the UK, who led the study. "In some sauropods this would have meant a graceful, swan-like S-curve to the neck, and a look quite different from the recreations we are used to seeing today."
