[ Watch the Video: Mummified Dino Fossil Had A Fleshy Head Crest ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from Australia's University of New England (UNE) and Italy’s University of Bologna have reportedly discovered the first evidence that dinosaurs had fleshy head ornaments similar to a rooster’s comb. As the study authors report in Thursday’s edition of the journal Current Biology, they discovered the head crest on a rare, mummified specimen of...

How Did Duck Billed Dinosaurs Get Through Dark, Polar Winters?
2012-04-12 06:21:02

Researchers from the University of Cape-Town, the Museum of Nature and Science in Dallas, and Temple University have discovered that duck-billed dinosaurs endured long, dark polar winters. These dinosaurs lived within Arctic latitudes approximately 70 million years ago, and rather than migrating south for the harsh winters, they simply stayed put. The paper, entitled “Hadrosaurs Were Perennial Polar Residents,” was published in the journal The Anatomical Record: Advances in...

Tyrannosaurus rex was an opportunistic feeder, not a top predator, paleontologists say The ferocious Tyrannosaurus rex has been depicted as the top dog of the Cretaceous, ruthlessly stalking herds of duck-billed dinosaurs and claiming the role of apex predator, much as the lion reigns supreme in the African veld. But a new census of all dinosaur skeletons unearthed over a large area of eastern Montana shows that Tyrannosaurus was too numerous to have subsisted solely on the dinosaurs it...

A new study suggests that a hadrosaur's jaw wasn't hinged in the same way as modern people and animals, answering a question that researchers have long wondered about how these ancient animals handled food. The researchers reported in Tuesday's edition of Proceeding of the National Academy of Sciences that the study focused on scratch marks on hadrosaur teeth. "For millions of years, until their extinction at the end of the Cretaceous, duckbilled dinosaurs "” or hadrosaurs "”...

University of Manchester scientists are using laser imaging to investigate how fat "“ or fit "“ T. rex and his fellow dinosaurs were. Karl Bates and his colleagues in the palaeontology and biomechanics research group have reconstructed the bodies of five dinosaurs, two T. rex (Stan at the Manchester Museum and the Museum of the Rockies cast MOR555), an Acrocanthosaurus atokensis, a Strutiomimum sedens and an Edmontosaurus annectens. The team, whose findings are published in the...

Contrary to popular belief, polar dinosaurs may not have traveled nearly as far as originally thought when making their bi-annual migration. University of Alberta researchers Phil Bell and Eric Snively have suggested that while some dinosaurs may have migrated during the winter season, their range was significantly less than previously thought, which means their treks were shorter. Bell and Snively's findings were recently published in Alcheringa: An Australasian Journal of Paleontology. The...

Researchers at North Dakota's state museum are scrupulously chipping away at a giant greenish-black 65-million-year-old rock, using tiny brushes and chisels to uncover a nearly complete dinosaur fossil, with skin and all.  Named Dakota, the fossil is unlike almost any other ever found, and was unearthed in 2004 in southwestern North Dakota. The Edmontosaurus is covered by fossilized skin that is hard as a rock, and among only a few mummified dinosaurs ever discovered. "This is the...

Edmontosaurus is a genus of a crestless hadrosaurid, meaning duck-billed, dinosaur. It includes two species: Edmontosaurus regalis and Edmontosaurus annectens. Fossils of E. regalis have been recovered in rocks of western North America that date from the late Campanian stage of the Cretaceous Period 73 million years ago, while those of E. annectens were recovered in the same geographic region but in rocks that dated to the end of the Maastrichtian stage of the Cretaceous, 65.5 million years...

Claosaurus, meaning "˜broken lizard', is a genus of hadrosaurid dinosaur from the Late Cretaceous Period (Santonian age). It got its name due to the odd display of its fossils in the bone bed, which appeared to be broken. It was first discovered near the Smokey Hill River in Kansas, USA in 1872. It was originally named Hadrosaurus agilis in 1872, but was changed to Claosaurus agilis in 1890 when major differences between the specimen and Hadrosaurus were discovered. A second species was...

Brachylophosaurus or "short-crested lizard" is a genus of dinosaur that was found in the Oldman Formation of Alberta, Canada in 1936. It was first described by Charles M. Sternberg in 1953. It remained the only described specimen until 1988, when Jack Horner described the specimen B. goodwini that was discovered in the Judith River Formation in Montana. A find by Nate Murphy in 1994 was a complete and uncrushed skeleton which he nicknamed "Elvis", and then he discovered another specimen in...

Anatotitan or "large duck" is a genus of flat-headed dinosaur commonly referred to as a "duck-billed dinosaur". It lived during the end of the Cretaceous Period, in what is now North America. Its remains have been preserved in the Hell Creek and Lance Formations dated 68 to 65 mya. They were among the last dinosaurs that existed on the planet before the extinction of all dinosaurs 65 million years ago. Like many dinosaurs, the history of Anatotitan is somewhat confusing. The original...
