Alaska's Denali National Park Holds 70M-Year-Old Dinosaur Footprints
2014-07-10 07:57:51

April Flowers for redOrbit.com - Your Universe Online Denali National Park covers over six million acres of land in the center of Alaska. One road bisects the park, leading from taiga forests to the highest mountain in North America, Mount McKinley. Today, many species of wildlife roam freely through the park. According to a new study led by the Perot Museum of Nature and Science, Denali was once home to large herds of duck-billed dinosaurs called hadrosaurs, as well. A remarkable...

Listed in the Guinness World Book of Records as having the best preserved dinosaur remains ever found, this fossilized duckbill dinosaur (Brachylophosaurus) gives scientists their first real look at the skin, the scales, the foot pads, and even the stomach contents of the behemoths that roamed the planet 77 million years ago. Indianapolis, IN (PRWEB) March 12, 2014 Leonardo, the mummified dinosaur, does not look like bones of a dinosaur puzzle carefully pieced together. In death, he looks...

[ Watch the Video: Baby Parasaurolophus Dinosaur ] Lee Rannals for redOrbit.com - Your Universe Online The Raymond M. Alf Museum of Paleontology at The Webb Schools announced on Tuesday one of its students has discovered the youngest, most complete fossil skeleton of a Parasaurolophus. Three-dimensional scans of the entire fossil have been made available for free online, making this dinosaur the most digitally accessible one to date. High school student Kevin Terris discovered the...

Intact Hadrosaur Tail Found
2013-07-23 12:07:09

Lee Rannals for redOrbit.com - Your Universe Online Paleontologists have uncovered 50 vertebrae of the only complete, articulated hadrosaur tail to be found in the desert of Coahuila in Mexico. The scientists carefully removed sedimentary rock that covered the vertebrae to discover the skeleton of a 72 million-year-old hadrosaur tail that reaches nearly 16-feet in length. The 50 vertebrae excavated remain bound together the same way as when the dinosaur inhabited the planet....

Duck-billed Dinosaurs Had Complex Grinding Teeth
2012-10-05 05:34:13

April Flowers for redOrbit.com - Your Universe Online A new study has found that duck-billed dinosaurs had an amazing capacity to chew tough and abrasive plants with grinding teeth more complex than those of modern grazers. The study, published in Science, is the first to recover material properties from fossilized teeth. The dinosaurs, also known as hadrosaurids, were the dominant plant-eaters during the Late Cretaceous — about 85 million years ago — in the areas now known...

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...

A new genus and species of hadrosaur (duck-billed) dinosaur "“ the oldest duck-billed dinosaur known from North America "“ has been named by scientists who expect the discovery to shed new light on dinosaur evolution. The most striking feature of Acristavus gagslarsoni, the name given to the new dinosaur, is that its head lacked the distinctive ornamentation common to later duck-billed relatives. Acristavus means "non-crested grandfather." The genus name is symbolic of the...

John R. “Jack” Horner (born June 15, 1946) is an American paleontologist known for his research on dinosaur growth, and for discovering evidence that some dinosaurs nested and cared for their young.  He is perhaps the most famous paleontologist due to his role as technical advisor for all three Jurassic Park films, and his providing inspiration for Dr. Alan Grant, the film's lead character. He also advised on the FOX television show Terra Nova. Horner was born and raised in the small...

Edmontosaurus

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...

Saurolophus, meaning “lizard crest,” is a genus of hadrosaurid dinosaur from the Late Cretaceous Period (70 million years ago) of what is now North America and Asia. It is one of the few genera of dinosaurs that is known from multiple continents. The first specimen was described by paleontologist Barnum Brown in 1911. The skeleton is now on display at the American Museum of Natural History and is the first nearly complete dinosaur skeleton found in Canada. It was found in rocks of the...

Prosaurolophus, meaning “before Saurolophus,” is a genus of hadrosaurid dinosaur from the Late Cretaceous Period (75 million years ago) of North America. It is known from the remains of at least 25 individuals belonging to two species. The first specimen was discovered in 1915 by paleontologist Barnum Brown at Red Deer River in Alberta, near Steveville. It was described as a new genus in 1916, based on its similarities to the genus Saurolophus, which he had described in 1912. Saurolophus...

Parasaurolophus, meaning “near-crested lizard,” is a genus of ornithopod dinosaur from the Late Cretaceous Period of what is now North America (76 to 73 million years ago). This genus is based on a skull and partial skeleton missing most of the tail and hind legs below the knees, which was found by a field party from the University of Toronto in 1920 near Sand Creek along the Red Deer River in Alberta, Canada. The rocks where the specimen was unearthed are known as the Campanian-age Upper...
