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.
The park is a favoured destination for palaeontologists, who have previously found other new species in the area including a Velociraptor-like carnivore called Hagryphus and a species of tyrannosaur.
“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.

Dinosaur Skeleton Found in Argentina

The skeleton of what could be a new dinosaur species _ a giant, Patagonian plant-eater _ has been uncovered in Argentina. At more than 105 feet, it is among the largest ever found, scientists said Monday.
Scientists from Argentina and Brazil said the Patagonian dinosaur appears to represent a previously unknown species because of the unique structure of its neck. They named it Futalognkosaurus dukei after the Mapuche Indian words for ‘giant’ and ‘chief,’ and for Duke Energy Argentina, which helped fund the skeleton’s excavation.
‘This is one of the biggest in the world and one of the most complete of these giants that exist,’ said Jorge Calvo, director of paleontology center of National University of Comahue, Argentina, lead author of a study on the dinosaur published in the peer-reviewed Annals of the Brazilian Academy of Sciences.
Scientists said the giant herbivore walked the Earth some 88 million years ago.
Since the first bones were found on the banks of Lake Barreales in the Argentine province of Neuquen in 2000, paleontologists have dug up the dinosaur’s neck, back region, hips and the first vertebra of its tail.
‘I’m pretty certain it’s a new species,’ agreed Peter Mackovicky, associate curator for dinosaurs at Chicago’s Field Museum, who was not involved with the discovery. ‘I’ve seen some of the remains of Futalognkosaurus and it is truly gigantic.’
Patagonia also was home to the other two largest dinosaur skeletons found to date _ Argentinasaurus, at around 115 feet long, and Puertasaurus reuili, between 115 to 131 feet long.
Comparison between the three herbivores, however, is difficult because scientists have only found few vertebrae of Puertasaurus and while the skeleton of Futalognkosaurus is fairly complete, scientists have not uncovered any bones from its limbs.
The site where Futalognkosaurus was found has been a bonanza for paleontologists, yielding more than 1,000 specimens, including 240 fossil plants, 300 teeth and the remains of several other dinosaurs.
