Recreating the spectacular pose many dinosaurs adopted in death might involve following the simplest of instructions: just add water. When palaeontologists are lucky enough to find a complete dinosaur skeleton – whether it be a tiny Sinosauropteryx or an enormous Apatosaurus – there's a good chance it will be found with its head thrown backwards and its tail arched upwards – technically known as the opisthotonic death pose. No one is entirely sure why this posture is so common, but Alicia Cutler and colleagues from Brigham Young University in Provo, Utah, think it all comes down to a dip in...

Some of the largest animals to ever walk on Earth were the long-necked, long-tailed dinosaurs known as the sauropods—and the most famous of these giants is probably Brontosaurus, the "thunder lizard." Deeply rooted as this titan is in the popular imagination, however, for more than a century scientists thought it never existed. The first of the Brontosaurus genus was named in 1879 by famed paleontologist Othniel Charles Marsh. The specimen still stands on display in the Great Hall of Yale's Peabody Museum of Natural History. In 1903, however, paleontologist Elmer Riggs found that Brontosaurus was apparently the same as the...

On the edge of the solar system, the dwarf planet Pluto, which knows what it feels like to be banished from an exclusive club, may be cheering for the brontosaurus. While the long-necked dinosaur's name may be known by legions of fans and even made it on to a postage stamp in the 1980s, most paleontologists would be quick to correct people that the brontosaurus is not a dinosaur. But the iconic dinosaur name may finally be reinstated more than a century after researchers found the long-necked brontosaurus and apatosaurus likely belonged to the same genus, according to an analysis...

It's official, long-necked sauropod dinosaurs once roamed every continent on Earth — including now-frigid Antarctica. The discovery of a single sauropod vertebra on James Ross Island in Antarctica reveals that these behemoths, which included Diplodocus, Brachiosaurus and Apatosaurus, lived on the continent in the upper Cretaceous Period about 100 million years ago.
