redOrbit Staff & Wire Reports - Your Universe Online A team of researchers led by Jahan Ramezani of MIT’s Department of Earth, Atmospheric and Planetary Sciences has discovered evidence that dinosaurs lived in North America millions of years earlier than previously suggested. Writing in the latest edition of the American Journal of Science, Ramezani and his colleagues state that precise dating of rocks which were found in the southern US and contained dinosaur fossils, suggest the...

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...

Fossil Discovery May Be Of Earliest Living Dinosaur

Lawrence LeBlond for redOrbit.com - Your Universe Online Some of the earliest known dinosaurs to have walked the planet were considered to be small dinosaurs like the swift-footed Eoraptor. But researchers have discovered a new dinosaur-like fossil that may be even older. Called Nyasasaurus parringtoni, the specimen is thought to have existed 10 to 15 million years earlier than dinosaur fossils have previously shown, originating in the Middle rather than the Late Triassic Period. Study...

The discovery of a 200-million year old fossil of a reptile with extremely pointed teeth, from an area now known New Mexico, is filling a gap in previously known dinosaur evolution, the Associated Press reports. Named Daemonosaurus chauliodus, from the Greek words "daimon" meaning evil spirit and "sauros" meaning lizard or reptile. Chauliodus is derived from the Greek word for "buck-toothed" and refers to the species' big slanted front teeth. This species featured a short snout and...

Scientists have unveiled fossils of one of the earliest dinosaurs ever discovered -- a petite, nimble carnivore from the late Triassic period some 230 million years ago. Dubbed Eodromaeus, or "dawn runner", the never-before seen species was a small, two-legged creature that may have been among the first dinosaurs to roam the Earth, making them likely ancestors of the famous Tyrannosaurus rex. The scientists reconstructed the dinosaur from a nearly complete set of bones found in Ischigualasto,...

A new species of dinosaur discovered in Arizona suggests dinosaurs did not spread throughout the world by overpowering other species, but by taking advantage of a natural catastrophe that wiped out their competitors. The new dinosaur, named Sarahsaurus, was studied by an international team of scientists, including Robert R. Reisz, professor and chair of biology at the University of Toronto Mississauga, Tim Rowe, professor of paleontology at the University of Texas at Austin's Jackson School...

New fossil material redefines Azendohsaurus as a peculiar early reptile Azendohsaurus just shed its dinosaur affiliation. A careful new analysis of A. madagaskarensis"”this time based on the entire skull rather than on just teeth and jaws"”aligns this 230-million-year-old animal with a different and very early branch on the reptile evolutionary tree. Many aspects of Azendohsaurus are far more primitive than previously assumed, which in turn means that its plant-eating adaptations,...

A team of paleontologists has unearthed a previously unknown meat-eating dinosaur from a fossil bone bed in northern New Mexico. The discovery settles a long-standing debate about early dinosaur evolution, and reveals a period of explosive diversification.  It also hints at how dinosaurs spread across the supercontinent Pangaea. A description of the new species, named Tawa after the Hopi word for the Puebloan sun god, appears in the Dec. 10 issue of the journal Science. The...

WASHINGTON -- Dinosaurs shared the Earth for millions of years with the species that were their ancestors, a new study concludes. Dinosaurs arose in the Late Triassic, between 235 million and 200 million years ago, and came to dominate the planet in the Jurassic, 200 million to 120 million years ago. Scientists had thought the dinosaurs rapidly replaced their ancestor species. Indeed, until 2003, when a creature called Silesaurus was discovered in Poland, no dinosaur precursors had been found...

NASA -- Palaeontologists from the University of Bonn report on an intriguing diagnosis in the 16 December issue of the journal Science. A dinosaur which they have examined was apparently able to vary the speed of its growth according the conditions obtaining in its environment. Although tortoises and crocodiles also do this, plateosaurus engelhardti seems to be unique among dinosaurs, leading experts to puzzle over whether the family history of the dinosaurs will need to be rewritten....

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,...

Plateosaurus, meaning “Broadway lizard,” is a genus of plateosaurid dinosaur from the Late Triassic Period (216 to 199 million years ago), which lived in what is now Central and Northern Europe. It is a primitive sauropodomorph dinosaur. There are two recognized species: the type species P. engelhardti from the late Norian and Rhaetian stages, and the slightly earlier P. gracilis from the lower Norian. Plateosaurus was discovered in 1834 by Johann Friedrich Engelhardt and described...

Segisaurus, meaning "Segi canyon lizard," is a genus of coelophysoid theropod dinosaur from the Early Jurassic Period (183 million years ago). It was discovered by a Navajo Indian -- Max Littlesalt -- in 1933 in Tsegi Canyon, Arizona, for which it was named. Segisaurus is the only dinosaur ever to be excavated from that area. Although it was described in 1936 by paleontologist Charles Lewis Camp, the specimen went relatively ignored for the next half century. When the specimen was...

Zupaysaurus, meaning "devil lizard," is a genus of theropod dinosaur from the Rhaetian stage of the Late Triassic, and possible the Hettangian stage of the Early Jurassic Period of what is now Argentina. It was discovered in the Los Colorados Formation of La Rioja province in Argentina. The formation is normally assigned to the Norian stage (216-203), but has also been assigned to the slightly younger Rhaetian stage (203-200 million years ago), where Zupaysaurus was found. The type...

Staurikosaurus, meaning "Southern Cross lizard," is a genus of dinosaur from the Carnian age of the Late Triassic Period (225 million years ago). The first known specimen was recovered from the paleontological site Jazigo Cinco of the Santa Maria Formation, in Rio Grande do Sul, Brazil. The genus name refers to the star constellation, "The Southern Cross," pictured in the coat of arms of Brazil, which is only visible in the southern hemisphere. In 1970, when Staurikosaurus was first...
