An international team of paleontologists has unearthed a new species of dinosaur in Inner Mongolia, China.  The dinosaur, named Linhenykus monodactylus after the nearby city of Linhe, was a miniature, single-clawed theropod, and was likely an early relative of the infamous Tyrannosaurus Rex, the researchers said. It is the only creature known to have just one finger, and would have been about three feet tall with the approximate weight of a parrot. The new species belongs to the...

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,...

While dinosaurs such as the Tyrannosaurus rex have long been assumed to be carnivorous, many of them were, in fact, vegetarians, according to a new study set to be published in the journal Proceedings of the National Academy of Sciences (PNAS). Paleontologists from the Field Museum in Chicago, Illinois, used statistical analysis in order to discern the dietary preferences of 90 species of theropods--bipedal, bird like dinosaurs that first appeared in the late Triassic period. Of those...

The flightless ostrich uses its wings very effectively in high-performance running and may provide valuable information about how its dinosaur ancestors moved, say researchers in Germany Once thought to be "evolutionary leftovers", new research has shown that ostriches in fact use their feathered forelimbs as sophisticated air-rudders and braking aids. According to the researchers, wing-use and hindlimb function in ostriches may help paleontologists in their quest to reconstruct locomotor...

Was it the other way around? A new study published in the Proceedings of the National Academy of Sciences provides yet more evidence that birds did not descend from ground-dwelling theropod dinosaurs, experts say, and continues to challenge decades of accepted theories about the evolution of flight. A new analysis was done of an unusual fossil specimen discovered in 2003 called "microraptor," in which three-dimensional models were used to study its possible flight potential, and it concluded...

Scientists' find describes how one family of dinosaurs came to look like birds--independent of birds Through an expedition to the Gobi Desert of China, scientists have solved the puzzle of how one group of dinosaurs came to look like birds--independent of birds. The discovery extends the fossil record of the family Alvarezsauridae--a bizarre group of bird-like dinosaurs with a large claw on the hand and very short, powerful arms--back 63 million years, further distancing the group from birds...

A team of paleontologists has unearthed a previously unknown meat-eating dinosaur from a fossil bone bed in northern New Mexico. The discovery settles a long-standing debate about early dinosaur evolution, and reveals a period of explosive diversification.  It also hints at how dinosaurs spread across the supercontinent Pangaea. A description of the new species, named Tawa after the Hopi word for the Puebloan sun god, appears in the Dec. 10 issue of the journal Science. The...

Fossil experts say the stunning remains of a "four-winged" dinosaur have confirmed that birds owe their ancestry to two-footed dinosaurs that lived millions of years ago, AFP reported. The well-preserved fossil of a bird-like dinosaur called Anchiornis huxleyi may be the deciding factor, according to Xing Xu of the Chinese Academy of Science in Beijing. Based on incomplete fossils, A. huxleyi was thought to have been a near contemporary of Archaeopteryx, the first recognized bird, which flew...

Two titans fighting a bloody battle "“ that often turns fatal for both of them. This is how big predatory dinosaurs like Tyrannosaurus are often depicted while hunting down their supposed prey: even larger herbivorous dinosaurs. The fossils, though, do not account for that kind of hunting behavior but indicate that theropods, the large predatory dinosaurs, were frying much smaller fish. Dr. Oliver Rauhut, paleontologist at Ludwig-Maximilians-Universität (LMU) in Munich, and his...

Scientists have uncovered a beaked dinosaur in China that is providing new clues into how birds' hands evolved to develop fingers.Writing in the journal Nature, scientist James Clark of George Washington University and Xu Xing of the Chinese Academy of Science's Institute of Vertebrate Paleontology and Paleoanthropology in Beijing detailed the new discovery, which was found amidst 159-million-year-old deposits in the Junggar Basin of Xinjiang."This finding is truly exciting, as it changes...

Velociraptor

Velociraptor, meaning “swift seizer” is a genus of dromaeosaurid theropod dinosaur that lived about 75 to 71 million years ago during the later part of the Cretaceous Period. There are two species that are presently recognized. The type species is V. mongoliensis; fossils of this particular species have been uncovered in Mongolia. A second species, V. osmolskae, it was named in 2008 for some skull material from Inner Mongolia, China. They are smaller than other dromaeosaurids such as...

Tarbosaurus

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...

Spinosaurus, meaning “Spine lizard,” is a genus of theropod dinosaur from the lower Albian to lower Cenomanian stages of the Mid Cretaceous Period (112 to 97 million years ago). It lived in what is now North Africa. The type species is S. aegyptiacus. A potential second species, S. maroccanus, was discovered in Morocco. It was the first known dinosaur fossil from Egyptian remains discovered in 1912 and described by German paleontologist Ernst Stromer in 1915. The original remains were...

Sinosauropteryx, meaning “Chinese reptilian wing,” is a genus of theropod dinosaur from the Late Jurassic to the Early Cretaceous Period 135 to 121 million years ago. It was discovered in 1996 by two Chinese farmers in the dry countryside near Liaoning Province, China. The same area has also produced later on other bird-like dinosaur fossils including Caudipteryx and Protarchaeopteryx. Three complete skeletons of Sinosauropteryx have been found, including few samples of protofeathers,...

Tyrannosaurus

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...
