Paleontology in Wyoming

Christie’s is auctioning the skeletons of an adult and a juvenile Allosaurus, sold as a pair, with an estimated price of between £5–8 million, as well as a Stegosaurus fossil, valued between £3–5 million.

The skeleton of a 22-meter-long dinosaur fetched six million euros ($6.4 million) on Nov. 16, AFP learned from auction houses Collin du Bocage and Barbarossa.

An anonymous collector snapped up the vegetarian apatosaurus, which was dug up in the United States, for 4.7 million euros rising to 6 million including costs.

The buyer pledged to allow it to be displayed in a museum.

Before a T. rex can tower over museum visitors or a Triceratops can show off its huge horns, dinosaur fossils must first be painstakingly reconstructed, cleaned, fit together and even painted.

For U.S. restorationist Lauren McClain, the process is like putting together a giant 3D puzzle.

New analyses of giant fossilized teeth are helping scientists unravel the mystery of their extinction

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.

Nearly 300 Tyrannosaurus rex bones that were dug up from three sites in the United States and assembled into a single skeleton sold Tuesday at an auction in Switzerland for 4.8 million francs ($5.3 million), below the expected price.

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.

Paleontologists in Portugal have unearthed the fossilized skeleton of what could be the largest dinosaur ever found in Europe.

The remains are thought to be those of a sauropod, a herbivorous dinosaur 12 meters (39 feet) tall and 25 meters long that roamed the Earth around 150 million years ago.

A drought in Texas dried up a river flowing through Dinosaur Valley State Park, exposing tracks from giant reptiles that lived some 113 million years ago, an official said on Aug. 23.

The world's biggest triceratops skeleton, known as "Big John," was sold for 6.6 million euros Oct. 21 to a private collector at a Paris auction house.
