Dinosaur Claws Were Used For More Than Just Ripping Flesh: Study
2014-05-07 12:08:20

Brett Smith for redOrbit.com - Your Universe Online The claws of Tyrannosaurus rex and Velociraptor are probably best known for ripping through the flesh of hapless prey, but a new study published in Proceedings of the Royal Society B has found that this family of dinosaurs, known as theropods, probably used its claws for a variety of purposes. In the study, Stephan Lautenschlager, from Bristol University, examined the differences in claw shape among theropods and analyzed them based...

Beaks Were Functionally Important In Protecting Dinosaur Skulls
2013-12-03 08:20:52

April Flowers for redOrbit.com - Your Universe Online One typical hallmark of modern birds that comes in a huge variety of shapes and sizes is the beak. While this is common knowledge, it is less well known that during the Cretaceous Period keratin-covered beaks had already evolved in different groups of dinosaurs. A international team of scientists, composed of Dr Stephan Lautenschlager and Dr Emily Rayfield of the University of Bristol with Dr Perle Altangerel of the National...

Study Peers Into Dinosaur Heads
2012-12-20 19:46:31

Lee Rannals for redOrbit.com — Your Universe Online Scientists found one dinosaur species had particularly well developed senses of smell, hearing and balance, which could be attributed to the extinct animal's big forehead. Scientists reported in PLOS ONE the well-developed senses in therizinosaurs might have affected or benefited from an enlarged forebrain. Researchers were surprised by the findings, because exceptional sensory abilities would be expected from predatory...

Evolution Of Theropods Linked To Environmental Factors

Alan McStravick for redOrbit.com - Your Universe Online The heaviest flying bird tops out at between 40-42 pounds. And sure, some of the flightless birds can grow to upwards of 300 pounds. But to imagine ancestors of these modern day creatures tipping the scales at upwards of 7,000 pounds is hard to do, indeed. A recent study out of North Carolina State University (NCSU) and the Field Museum in Chicago, Illinois, looks specifically at the feathered herbivores of the Cretaceous period...

New Dinosaur Species Is Largest Known Feathered Animal

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...

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...

A team of paleontologists, including a University of Pennsylvania doctoral candidate, has described a new species of dinosaur based upon an incomplete skeleton found in western New Mexico. The new species, Jeyawati rugoculus, comes from rocks that preserve a swampy forest ecosystem that thrived near the shore of a vast inland sea 91 million years ago. The dinosaur, whose name translates to mean "grinding-mouth, wrinkle-eye," was most likely an herbivore that ate the ferns and conifer trees...

A new dinosaur species found in southern Utah has been identified, a fearsome looking creature that ate only plants, researchers say. Lindsay Zanno, a paleontologist at the Field Museum in Chicago, and her colleagues described Nothronychus graffami in a paper published Tuesday in Proceedings of the Royal Society B: Biological Sciences, the Chicago Sun-Times reported. The species is related to the velociraptor, the carnivorous dinosaurs made famous by the book and movie Jurassic Park, and to...

Scientists have caught a dinosaur in the act of evolving from meat-eater to vegetarian. The two-legged, feathered creature ate plants, but its bones show that the transition from its carnivorous ancestors was still in progress. All plant-eating dinosaurs were ultimately descended from a meat-eater, and switchovers to plant-eating occurred several times. The newly discovered species, which lived 125 million years ago in what is now Utah, could help scientists understand details of how the...

Segnosaurus, meaning "slow lizard," is a genus of therizinosaurid theropod dinosaur from the Cenomanian to Turonian stages of the Late Cretaceous Period. The type species, S. galinensis, was described in 1979 by Dr. A. Perle. It is known from three specimens consisting of a mandible, pelvis, hind limb, partial forelimb and vertebrae, as well as other fragments. The specimens were recovered from the Bayan Shireh Formation of the Mongolian People's Republic. Segnosaurus can be distinguished...

Suzhousaurus is a genus of therizinosaurid dinosaur from the Early Cretaceous Period. It was discovered in the Xinminpu Group of the Yujingzi Basin, Gansu, China. It was described by Li et al., who performed a cladistic analysis and found that Suzhousaurus is more derived than Beipiaosaurus and Falcarius, less derived than Alxasaurus and true therizinosaurids, and a relative of Nothronychus. Suzhousaurus is one of the largest known Early Cretaceous therizinosaurids, along with...

Nothronychus, meaning "slothful claw", is a genus of dinosaur from the mid-Turonian age of the Late Cretaceous Period (91 million years ago). It was discovered in the Moreno Hill Formation in the Zuni Basin, on the border of New Mexico and Arizona. The type species, N. mckinleyi, was described in 2001. A second species, N. graffami, was discovered in the Tropic Shale Formation of Utah. This specimen dated back about a million years before the nominate species. Nothronychus had a toothless...

Nanshiungosaurus is a genus of dinosaur from the Late Cretaceous Period that lived in what is now China. There are two known species: N. brevispinus was discovered in the Yuanpu Formation and N. bohlini was discovered from the Xinminbao Group. Only partial remains have been found which do not include the skull, tail, ribs or limbs. Analysis of this genus is based on the vertebrae and pelvis alone. At first, this dinosaur was thought to be a strange type of sauropod, but with the...

Falcarius, meaning "sickle cutter", is a genus of dinosaur from the Early Cretaceous Period (130 to 125 mya). This therizinosaurid dinosaur was the first of its kind to be found in North America. The fossils were found in east-central Utah, USA in 2005. Based on fossils recovered from another closely related specimen in China, scientists may clarify this specimen's relationship to the larger family of theropod dinosaurs. The site of discovery, Cedar Mountain Formation, was only a 2 acre plot....
