Study: Allosaurus Ate Less Like A Crocodile, More Like A Falcon
April Flowers for redOrbit.com – Your Universe Online To dismember its prey, the mighty Tyrannosaurus rex thrashed its massive head from side to side. T. rex’s smaller cousin, the Allosaurus, was a more dexterous hunter and tugged at prey...

redOrbit Staff & Wire Reports - Your Universe Online A set of fossil remains discovered in northwestern China back in 2006 have been classified as a new species of carnivorous dinosaur belonging to the same suborder as the Tyrannosaurus rex. The theropod fossils were discovered in a remote region of Xinjiang and included a skull, a mandible and a partial skeleton of the dinosaur. The creature, which was named Aorun zhaoi in honor of the Dragon King from the Chinese literary work...
Peter Suciu for redOrbit.com – Your Universe Online While these never actually walked the Earth, and didn’t fully develop or hatch, a trove of dinosaur embryos could give researchers rare insight into their development. Paleontologists working in China recently unearthed what could be the earliest collection of fossilized dinosaur embryos to date, and it has provided the researchers with a new opportunity to study ongoing growth patterns and development of the prehistoric species....
Lawrence LeBlond for redOrbit.com - Your Universe Online When you inspect the legs of most birds you will find everything from the knee down is scaly rather than feathery. There is an exception to this rule however. Some birds of prey, such as eagles, have more feathering below the knee extending down to the feet. As for those with scaly legs, it is a remnant of their ancestry, when birds evolved from small two-legged dinosaurs millions of years ago. For the most part, experts...
Lawrence LeBlond for redOrbit.com – Your Universe Online The Brontosaurus has been one of the most well-known dinosaurs in popular culture for more than a hundred years. It has been portrayed in books, on TV, and in cinema and has also had its likeness put on a US postage stamp in 1989, albeit with a good dose of controversy and criticism. And while the Brontosaurus has been a mainstay in popular culture for decades, the actual use of the word Brontosaurus was discarded by science...
Brett Smith for redOrbit.com - Your Universe Online A pair of U.K. biologists has revived an older and heavily debated theory that suggests sauropod dinosaurs reached their massive sizes due to the plants they ate. About ten years ago, plant ecologists from South Africa originally formulated this theory; however their ideas have fallen out of favor with many dinosaur researchers. According to a paper from David Wilkinson of Liverpool John Moores University (LJMU) and Graeme Ruxton...
[ Watch the Video: Making of Heterodontosaurus Flesh Model ] Lee Rannals for redOrbit.com - Your Universe Online Scientists have unveiled new details about a fanged dinosaur with a parrot-shaped beak known as Pegomastax africanus. A single specimen of the new species was first uncovered in southern Africa in the 1960's, but new details of the dinosaur's anatomy and lifestyle have been published in the journal ZooKeys. Scientists report that Pegomastax had fangs, but was more in...
April Flowers for redOrbit.com - Your Universe Online A team of researchers from the University of Bristol, Natural History Museum of London, the University of Missouri and Ohio University report they have discovered the eating habits of the Jurassic age dinosaur, the Diplodocus. Found nearly 130 years ago, the eating habits of the giant herbivore were still largely uncertain until now. Understanding these habits could provide insights into extinct ecosystems and today's modern animal...
redOrbit Staff & Wire Reports - Your Universe Online A great number of hypotheses have been suggested on feeding behavior of Diplodocus - thought to be one of the largest dinosaurs ever since its discovery over 130 years ago. These range between standard biting, combing leaves through peg-like teeth, ripping bark from trees similar to behavior in some living deer, and even grabbing shellfish from rocks. A team of international researchers, led by the University of Bristol and the...
Brett Smith for redOrbit.com - Your Universe Online One of the most complete dinosaur fossils ever discovered suggests that feathered dinosaurs were more prevalent than previously thought and could have been the norm, not the exception. The 150 million-year-old fossil found in northern Bavaria shows that the dinosaur had down-like feathers over parts of its front and back as well on its tail. Scientists dubbed the creature Sciurumimus albersdoerferi after "Scirius”, the scientific...
Dinosaurs, some of the largest creatures to have ever walked the earth, have for the first time been accurately weighed by scientists using a new technique, and the results indicate that we have been guilty of wrongly portraying them as massively heavy beasts. Biologists at the University of Manchester, using lasers to calculate body mass, measured the minimum amount of skin that would be required to contain the skeletal structure of modern-day mammals, including reindeer, polar bears, and...

Supersaurus, meaning “super lizard” is a genus of diplodocid sauropod dinosaur that was discovered by Vivian Jones of Delta, Colorado, in the Upper Jurassic Morrison Formation of Colorado in the year 1972. The fossil remains came from the Brushy Basin Member of the formation, dating back to about 153 million years ago. It’s among the largest dinosaurs known from good remains, possibly reaching 108 to 112 feet long and around 35 to 40 tons. In most respects, Supersaurus is much like...
Megalaosaurus, meaning “Great Lizard”, from Greek megalo, meaning ‘big’ or ‘tall’ and sauros, meaning “lizard”, is a genus of large and meat-eating theropod dinosaurs of the Middle Jurassic period of Europe. It’s significant as the first genus of dinosaur, outside of birds, to be described and named. Megalosaurus might have been the first dinosaur to be described in scientific literature. Part of a bone was recovered from a limestone quarry at Cornwell by Chipping Norton,...
Stegosaurus, meaning “roof lizard,” is a genus of stegosaurid armored dinosaur from the Kimmeridgian to early Tithonian stages of the Late Jurassic Period (145 mya) in what is now western North America. It was first discovered from a bone bed in the Morrison Formation in Morrison, Colorado, and was first described in 1877 by Othniel Charles Marsh. These first fossils became known as the type species S. armatus. Marsh initially believed the remains were from an aquatic turtle-like...
Sauroposeidon, meaning “earthquake god lizard,” is a genus of sauropods dinosaur from the Aptian and Albian ages of the Early Cretaceous Period (110 million years ago). It was discovered in the southeast region of Atoka County, Oklahoma, not far from the border of Texas, in a claystone outcrop. The fossils were initially misidentified as pieces of petrified wood when they were found in 1994. A more detailed analysis in 1999 revealed they were truly dinosaurian bones. They were formally...
Massospondylus, meaning “longer vertebrae,” is a genus of prosauropod dinosaur from the Hettangian to Pliensbachian ages of the Early Jurassic Period (200 to 183 million years ago). Massospondylus was discovered in 1853 by J.M. Orpen in the Upper Elliott Formation at Harrismith, South Africa. It was described in 1854 by Sir Richard Owen. It is one of the first dinosaurs to have been named. The type species is M. carinatus. There have been seven other named species during the past 150...
