Duck-billed dinosaur had big bite
A species of dinosaur that packed hundreds of teeth inside its giant beak has just been described by scientists.
The Gryposaurus, discovered in southern Utah, had a distinct duck-like bill and a powerful, strengthened jaw.
The two-legged creature, described in the Zoological Journal of the Linnean Society, was more than 10m (30ft) long.
Analysis suggests that the dinosaur, which lived in the Cretaceous forests of North America about 65-80 million years ago, was a successful herbivore.
“When you combine the 800 teeth with the very large, strong jaw and beak you have a very formidable plant eater,” said Dr Terry Gates of the Utah Museum of Natural History, one of the authors on the paper.
Gryposaurus monumentensis was found in Grand Staircase-Escalante National Monument in Utah.
“We also have several other types of herbivores, including three new species of horned dinosaur, some domed dinosaurs and armoured dinosaurs,” Dr Gates told the BBC World Service’s Science in Action programme.
“There were lots of animals living in the ecosystem.”
At the time, North America was thought to be split by a shallow sea, dividing the continent into two.
The new species is believed to have lived on the western landmass on a strip of land running between the waterway and a range of mountains to the west.
The recently described specimen was probably fossilised when it was covered by river sediments that now make up a series of sandstones and mudstones known as the Kaiparowits Formation.
