2012-04-05 06:52:09

A new species of giant, feathered dinosaur discovered in northeastern China is the largest known feathered animal —- living or extinct -- ever to have existed, scientists reported on Wednesday. Xing Xu and from the Chinese Academy of Sciences in Beijing and colleagues discovered three nearly-complete skeletons of the dinosaur, named Yutyrannus huali, meaning "beautiful feathered tyrant", in beds of sediment in Liaoning province.  The meat-eating creatures, known as...

According to new research, the Tyrannosaurus Rex, which has traditionally been seen as a lone wolf kind of dinosaur, hunted in packs. The new research based on finds in the Gobi Desert suggests that the species was equipped with the build and speed for pack hunting, but also the brain capacity to work together as a team. Dr. Philip Currie of the University of Alberta said evidence from 90 skeletons of Tarbosaurus Bataar, a cousin of Tyrannosaurs Rex, suggests that about half a dozen of the...

A new study from an international team of scientists suggests juvenile and adult predatory dinosaurs had a range of hunting and feeding strategies. While adult tyrannosaurs wielded size and power to take down large prey, juveniles relied on their agility to hunt smaller game. "It's one of the secrets of success for tyrannosaurs"”the different age groups weren't competing with each other for food because their diets shifted as they grew," said Ohio University paleontologist Lawrence...

A gigantic theropod dinosaur measuring 11 meters long (36 feet), four meters tall (13 feet) and weighing in at six tons has been discovered in eastern China. Scientists named this new dinosaur Zhuchengtyrannus magnus, which means the "Tyrant from Zhucheng," since the bones were found in the city of Zhucheng in eastern China's Shandong Province. The quarry in Shandong Province, where the fossils were discovered, has one of the largest concentrations of dinosaur bones in the world. This is...

Scientists have unveiled fossils of one of the earliest dinosaurs ever discovered -- a petite, nimble carnivore from the late Triassic period some 230 million years ago. Dubbed Eodromaeus, or "dawn runner", the never-before seen species was a small, two-legged creature that may have been among the first dinosaurs to roam the Earth, making them likely ancestors of the famous Tyrannosaurus rex. The scientists reconstructed the dinosaur from a nearly complete set of bones found in Ischigualasto,...

Tyrannosaurs are more than large carnivores at the top of the food chain We've all heard this story: the Late Cretaceous of Asia and North America"”about 65 million years ago"”was dominated by several large-headed, bipedal predatory dinosaurs like Tyrannosaurus rex and Tarbosaurus that had tiny arms. But a decade of new fossil discoveries that have more than doubled the number of known tyrannosaur species has changed this tale. Older and smaller tyrannosaurs have made the...

Scientists have uncovered a hip bone believed to belong to an ancestor of the Tyrannosaurus Rex in Australia, providing the first evidence that the fearsome carnivore may have lived in the southern hemisphere, according to a Thursday University of Cambridge press release. The 30 centimeter long bone was discovered in Dinosaur Cove in Victoria by a team of researchers that included Dr. Roger Benson from the University of Cambridge's Department of Earth Science, Dr. Paul Barrett from the...

Scientists have uncovered new clues about the early stages of the Tyrannosaurus rex's beginnings. A team of British and German researchers studied a fossil held at London's Natural History Museum. They have concluded that the remains, which belong to a dinosaur named Proceratosaurus, may be the earliest known relative of the T. rex. Scientists say Proceratosaurus roamed the earth about 165 million years ago, during the middle Jurassic Period. He stood on two legs, was carnivorous, and would...

Carnivorous but smaller T. rex relative shared environment with larger cousins Now, just a few weeks after tiny, early Raptorex kriegsteini was unveiled, a new wrench has been thrown into the family tree of the tyrannosaurs. The new Alioramus altai"”a horned, long-snouted, gracile cousin of Tyrannosaurus rex"”shared the same environment with larger, predatory relatives. A paper published this week in the Proceedings of the National Academy of Sciences describes this exceptionally...

The Tyrannosaurus Rex is characterized by its big head, packed with sharp teeth, and tiny arms. However, a new ancestor has been dug up in China that was only 10 feet tall and 150 pounds, aptly nicknamed "Raptorex." Though the mini Raptorex is almost 100 times smaller than the T. rex, it is practically identical in structure, even sporting the same little arms and all the fortunate traits that made it such a successful predator, said lead author Paul Sereno from the University of Chicago and...

Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...

Tarbosaurus, meaning “alarming lizard” is a genus of tyrannosaurid theropod dinosaur that thrived in Asia about 70 million years ago, at the end of the Late Cretaceous Period. Fossils have been uncovered in Mongolia, with more incomplete remains found further afield in parts of China. Many species have been named, although, modern paleontologists recognize only one, T. bataar, as legitimate. Like most tyrannosaurus, Tarbosaurus was a sizeable bipedal predator, weighing up to six...

Tyrannosaurus, meaning “tyrant lizard,” was a genus of theropod dinosaur from the Late Cretaceous Period (68 to 65 million years ago). It was among the last non-avian dinosaurs to exist prior to the Cretaceous-Tertiary extinction event. Perhaps the most famous Tyrannosaurus species, T. rex, was named in 1905 by Henry Fairfield Osborn, president of the American Museum of Natural History (AMNH). Teeth belonging to Tyrannosaurus were first discovered in 1874 by A. Lakes near Golden...

Xiongguanlong, named after the city of Jiayuguan in northwestern China, is a genus of tyrannosauroid dinosaur from the Aptian to Albian ages of the Early Cretaceous Period (100 to 125 million years ago). The type species, X. baimoensis, was described in 2009 by a group of researchers from China and the USA. The species name, baimoensis, means "white ghost", after "white ghost castle", a rock formation near where the fossil was found. Xiongguanlong was a medium-sized tyrannosauroid. It...

Labocania, meaning "red lips"(named for the La Bocana Roja Formation), is a genus of theropod dinosaur from the Campanian age of the Late Cretaceous Period (70 million years ago). It lived in what is now Baja California, Mexico. The type species, L. anomala, was described in 1974 by Ralph Molnar. Labocania is known only from fragmentary remains, and its physical characteristics are not well known. There is some speculation that it may be closely similar to tyrannosaurid dinosaurs, but...
