April Flowers for redOrbit.com - Your Universe Online What do New Mexico and Alberta, Canada, have in common? Perhaps not much today, but millions of years ago they were both inhabited by closely related species of ankylosaurid dinosaurs, according to a study from the University of Alberta, New Mexico Museum of Natural History and the State Museum of Pennsylvania. The findings, published in PLOS ONE, describe a newly discovered species of armored dinosaur found in the Bisti/De-Na-Zin...

asteroid impact

April Flowers for redOrbit.com - Your Universe Online Approximately 66 million years ago, a relatively small chunk of rock changed the entire face of the planet. A meteorite, approximately 6 miles in diameter, impacted the Earth near the present-day site of the town of Chicxulub, in the Yucatan. With a force nearing that of 100 teratons of TNT, the meteorite left a crater nearly 100 miles wide and set off a megatsunami, wildfires, global earthquakes and volcanism that, to our knowledge,...

John Hopton for redOrbit.com - Your Universe Online Fossils discovered in China are providing clues to a species of flying reptile that may have had a jaw pouch for catching and storing food. The pterosaurs lived around 120 million years ago and scientists working on the project noted that as well as being similar to pelicans, they resembled the fictional winged creature Ikran from the movie Avatar. So much so they named it Ikrandraco avatar. Pterosaurs, which are more closely related...

April Flowers for redOrbit.com - Your Universe Online When we think of dinosaurs, we think of giant, scary reptiles that once ruled the Earth. But even giant monsters were babies at one point. And apparently, even dinosaur babies need a babysitter. A new study, led by the University of Pennsylvania, examined a rock slab from northeastern China's Liaoning Province containing fossils of 24 very young dinosaurs and one older individual. This kind of grouping is suggestive of a group of...

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered nearly 50 bones belonging to a new species of winged reptile with a bizarre head crest comparable to a butterfly or a yacht sail, various media outlets reported earlier this week. The new creature, identified as Caiuajara dobruskii, lived in southern Brazil during the Cretaceous period. The remains were discovered in a pterosaur bone bed from an interdunal lake deposit from an ancient desert, and it...

April Flowers for redOrbit.com - Your Universe Online An international team of scientists has discovered what they believe to be the earliest example of social behavior in bird-hipped dinosaurs, along with a brand new species, in the Andes Mountains of Venezuela. The new species is described in the journal Proceedings of the Royal Society B: Biological Sciences. Until now, researchers have assumed this region was not home to dinosaurs because of the large deserts that surround it. The...

redOrbit Staff & Wire Reports - Your Universe Online Newly-discovered fossils belonging to the largest four-winged dinosaur ever found could help shed new light on how the creatures were able to fly, according to research published online Tuesday in the journal Nature Communications. The creature, which has been named Changyuraptor yangi, was discovered in 125-million-year-old sediments in the Liaoning Province of northeastern China, according to Michael Balter of Science. It was...

April Flowers for redOrbit.com - Your Universe Online For the last 15 summers, research teams from the Museum of the Rockies have been exploring the badlands of Eastern Montana to excavate dinosaur bones from the Hell Creek Formation. Those teams have made many exciting and important discoveries regarding some of the last dinosaurs to walk our planet. Their latest study, published in the Proceedings of the National Academy of Sciences, involves the evolution of perhaps one of the most...

April Flowers for redOrbit.com - Your Universe Online Earth is full of evidence that dinosaurs once walked our planet. From fossil fuels to fossils themselves, the dinosaurs left their mark. These prehistoric creatures also left their footprints. Footprints can be found from Texas to China, tantalizing the imagination of the public and researchers alike. Such tracks have been found in an ancient seabed in China that, according to an international research team from the University of...

redOrbit Staff & Wire Reports - Your Universe Online While working at a remarkable fossil site in China, a team of paleontologists has managed to unearth not only the first-ever three-dimensionally preserved pterosaur eggs, but at least dozens of bones representing an entirely new genus and species of the creature as well. According to research published Thursday in the Cell Press journal Current Biology, the study authors found a population of sexually dimorphic pterosaur species...

Edwin Harris Colbert (September 28, 1905 – November 15, 2001), known as “Ned” to his friends and colleagues, was a distinguished American Paleontologist. He helped popularize the study of dinosaurs through his prolific research, writings, and 40 years of work as a curator at the American Museum of Natural History in New York. Colbert was born in Clarinda, Iowa, but moved to Maryville, Missouri during infancy. Like many young children, and most of his predecessors and contemporaries,...

Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American paleontologist, specializing primarily in vertebrates. He is highly renowned as one of the most prominent scientists of his time, having discovered and described dozens of new species. Marsh is also credited with developing what is currently the most widely accepted theory of the origin of birds. Marsh was born in Lockport, New York, to a family of moderate means. Thanks to the generosity of his uncle, George...

Styracosaurus
2013-04-29 14:54:48

Styracosaurus, meaning “spiked lizard” from the Ancient Greek styrax “spike at the butt-end of a spear-shaft” and sauros “lizard” was a genus of herbivorous ceratopsian dinosaur from the Cretaceous Period, about 76.5 to 75 million years ago. It had four to six long horns, stretching from its neck frill, a smaller horn on each cheek, and a single horn jutting out from its nose, which may have been up to 2 feet long and 6 inches wide. The function/functions of these horns and frills...

Thescelosaurus

Thescelosaurus, meaning “godlike”, “wondrous”, or “marvelous” and “lizard” was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Paleogene extinction event around 65.5 million years ago. The completeness and preservation of many of its specimens illustrate that it might have preferred to live near streams. This bipedal ornithopod is known from...

Daspletosaurus

Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...
