Scientists say they have discovered a 350-million-year-old scorpion fossil, recovered from Devonian formation layers in Grahamstown, South Africa.
Mass extinction certainly sounds like it would be the end of the line, and perhaps even evoke images of the end of the world. However, new research suggests that the end can also be the beginning.
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.
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.
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 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.
A team of experts from Brazil and Japan say they have discovered their version of Atlantis, or at least an ancient piece of granite that was part of a continent that disappeared nearly a hundred million years ago when Africa and South America separated.
Scientists writing in the journal Nature Communications have identified a new species of dog-sized bone-headed (pachycephalosaur) dinosaur. The dinosaur, Acrotholus audeti, represents the oldest bone-headed dinosaur in North America, and possibly the world, dating back 85 million years ago.
Nearly a year after a dinosaur fossil was first reported stolen from Mongolia it is finally being returned to its rightful owner. US authorities in New York have returned the remains of the 70-million-year-old Tyrannosaurus bataar to the Mongolian government.
New research reveals that the flying Microraptor dinosaur was a capable aquatic hunter as well and was able to swoop down and pluck fish out of the water.
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, 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, 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, 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...
