King Of Gore: Super Predator Cousin Of T. Rex Found In Utah
2013-11-07 14:47:55

Alan McStravick for redOrbit.com - Your Universe Online You may have noticed your local paleontologist has had an extra bounce in his step this week. That might have something to do with a monumental find of a new super-predator dinosaur in the Wahweap Formation within the Grand Staircase-Escalante National Monument in south-central Utah. Known as Lythronax argestes, this super predator lived 80 million years ago and is a distant, older cousin to the larger Tyrannosaurus rex. Measuring...

Mammal Diversity Faltered When Flowering Plants Arrived
2013-10-02 16:02:24

Brett Smith for redOrbit.com - Your Universe Online As mammals were trying to emerge from the shadows of dinosaurs 100 million years ago, there was a dramatic proliferation of flowering plant species. However, instead of early mammals benefiting from new food and shelter opportunities that would have been provided by the plants, they experienced a decline during the mid-Cretaceous. Using a morphological analysis, two researchers were able to provide these new insights about mammalian...

Ancient Crocodile Diversity
2013-09-11 12:31:02

[ Watch the Video: Crocodiles Thrived During Prehistoric Times ] Brett Smith for redOrbit.com - Your Universe Online Ancient relatives of crocodiles had a wide range of habitats and ecosystems, with some species built like domestic dogs and others built for swimming through the open seas. Using a combination of morphological and biomechanical metrics to analyze these ancient crocodilians, a new study from researchers at the University of Bristol in the UK identified distinct trends...

Earliest Known Scorpion Fossil Discovered In South Africa
2013-09-03 12:41:53

Lee Rannals for redOrbit.com - Your Universe Online Scientists publishing a study in the journal African Invertebrate say they have discovered a 350-million-year-old fossilized scorpion. The specimen, discovered in rocks from the Devonian Witteberg Group near Grahamstown, is a new species of scorpion called Gondwanascorpio emzantsiensis. Dr Robert Gess, from the Evolutionary Studies Institute at Wits University, discovered the specimen, which is said to be the oldest known land-living...

End-Permian Mass Extinction Paved Way For Modern Mammals
2013-08-28 16:19:55

Peter Suciu for redOrbit.com - Your Universe Online Mass extinction certainly sounds like it would be the end of the line, and perhaps even evokes images of the end of the world. However, new research conducted by the University of Lincoln, the National Museum in Bloemfontein, South Africa, and the University of Bristol suggests that the end can also be the beginning. This research, which was published this month in the Proceedings of the Royal Society B, noted that the ancient closest...

Dinosaur Skull Analysis Shows Three Species Are Actually One
2013-08-11 04:56:11

redOrbit Staff & Wire Reports - Your Universe Online A number of Psittacosaurus fossils, once believed to represent three different species, actually all belong to a single dinosaur species, researchers from the University of Pennsylvania claim in a new study. Differences in the specimens had led scientists to label them as separate species, senior author Peter Dodson, a professor of anatomy in Penn's School of Veterinary Medicine and professor of paleontology in the School of Arts...

High Diversity Of Flying Reptiles 110 million Years Ago In England
2013-06-12 16:19:23

Pensoft Publishers Brazilian paleontologists Taissa Rodrigues, of the Federal University of Espirito Santo, and Alexander W. A. Kellner, of the National Museum of the Federal University of Rio de Janeiro, have just presented the most extensive review yet available of toothed pterosaurs from the Cretaceous of England. The study features detailed taxonomic information, diagnoses and photographs of 30 species and was published in the open access journal ZooKeys. Pterosaurs from the...

Study: Allosaurus Ate Less Like A Crocodile, More Like A Falcon
2013-05-22 10:42:47

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 more like a modern day falcon, a new study from Ohio University shows. "Apparently one size doesn't fit all when it comes to dinosaur feeding styles," said Ohio University paleontologist Eric Snively. "Many people think of Allosaurus...

Ichthyosaur Fossil Indicates Dolphin-Like Dinos Survived Into Jurassic
2013-05-15 14:43:09

Brett Smith for redOrbit.com - Your Universe Online A fossil previously used as a stepping stone for mules has deepened the mystery surrounding the evolution of ichthyosaurs, dolphin-like marine reptiles that were contemporaries of the dinosaurs. According to a newly published report in the journal“¯Biology Letters,“¯an analysis of the fossil, dubbed Malawania anachronus, has suggested that ichthyosaurs survived well into the...

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

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...
