Remains of a species of herbivorous dinosaur previously unknown in the southern hemisphere have been discovered in Chile, challenging long-held beliefs about the range of duck-billed dinosaurs, scientists said on June 17.

Measuring up to four meters in length and weighing a ton, Gonkoken nanoi lived 72 million years ago in the extreme south of what is now Chilean Patagonia.

The Tyrannosaurus rex is often shown baring massive, sharp teeth, like the ferocious creature in "Jurassic Park." But new research suggests that this classic image might be wrong.

A Tyrannosaurus-Rex skeleton dating back 67-million years will be auctioned in Switzerland next month, marking the first such sale in Europe, the auction house said on March 11.

The skeleton dubbed Trinity will go under the hammer in Zurich on April 18, the Koller auction house said.

A skeleton of a Gorgosaurus dinosaur is going up for auction for the first time and is expected to fetch between $5 million and $8 million, Sotheby's said on July 5. 

The auction house will put the specimen, which is 10 feet tall (three meters) and 22 feet long, under the hammer in New York on July 28.

The new specimen of ancient flying reptile, or pterosaur, measured around 30 feet (9 meters) long

Argentine paleontologists have announced the discovery of an apex-predator dinosaur that measured three stories from nose to tail and eviscerated its prey with sharp, curved claws.

The six-ton giant, the largest megaraptor unearthed to date, fed on smaller dinosaurs that it ripped to shreds with its talons before digging into their intestines, paleontologist Mauro Aranciaga told AFP.

Birds are descended from a dinosaur species called Oviraptorosaurs

“It became clear years ago that paleontologists were not just neglecting to test dinosaur bones for C-14 content but were refusing to”

They will be replaced with other colleagues

The huge African predator Spinosaurus spent much of its life in the water, propelled by a paddle-like tail while hunting large fish - a "river monster," according to scientists, that showed that some dinosaurs invaded the aquatic realm.
