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...

Tiny New Dinosaur Helps Understand Ancient Ecosystem

April Flowers for redOrbit.com - Your Universe Online Although most of us imagine dinosaurs as large, fierce animals, a team of paleontologists from the University of Toronto, Royal Ontario Museum, Cleveland Museum of Natural History and University of Calgary“¯have highlighted a previously overlooked diversity of small dinosaurs. The study, published in the Journal of Vertebrate Paleontology, describes a new dinosaur — the smallest plant-eating dinosaur species known from...

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...

Feathered Dinosaurs May Have Been The Norm

Brett Smith for redOrbit.com - Your Universe Online One of the most complete dinosaur fossils ever discovered suggests that feathered dinosaurs were more prevalent than previously thought and could have been the norm, not the exception. The 150 million-year-old fossil found in northern Bavaria shows that the dinosaur had down-like feathers over parts of its front and back as well on its tail. Scientists dubbed the creature Sciurumimus albersdoerferi after "Scirius”, the scientific...

The rise of the tyrants of the South The stubby arms of Tyrannosaurus rex obviously weren't designed for hand-to-hand combat. However, the abelisaurids of the Southern hemisphere were even less well equipped in that department—and upper limb reduction began very early in their evolution. When Tyrannosaurus and its relatives roamed North America and Asia, the abelisaurids occupied a similar niche in Patagoniaand other areas ofGondwanaland. They were the dominant predators in the...

Some Dinosaurs Were Already Dying Out Before Asteroid Impact

Lawrence LeBlond for RedOrbit.com [ Watch the Video ] An asteroid impact may have ended the reign of the dinosaurs here on Earth about 65 million years ago, but new evidence suggests many of the large, plant-eating dinosaurs were already dying out during the last 12 million years of the Cretaceous period. The findings, by an international team of US and German scientists, do not dispute the mass extinction that killed off all the dinosaurs at the end of the Cretaceous era. They do,...

A team of researchers at the University of Bristol decided to find out, with investigations of dinosaur and human evolution. Their study, which is published this week in Proceedings of the Royal Society B, suggests most fossil discoveries do not make a huge difference, confirming, not contradicting our understanding of evolutionary history. This is especially true of the fossil record of human origins from their monkey relatives. Even though early human fossils are immensely rare, and new...

Paleontologists have discovered a dinosaur-like animal that lived 10 million years earlier than the oldest known dinosaurs, suggesting that dinosaurs and close relatives such as pterosaurs (flying reptiles) originated much earlier than scientists previously thought. The research also suggests that at least three times in the evolution of dinosaurs and their closest relatives, meat-eating animals evolved into animals with diets that included plants. These shifts all occurred in less than 10...

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...

Psittacosaurus, meaning “parrot lizard,” is a genus of ceratopsian dinosaur from the Early Cretaceous Period of what is now Asia (130 to 100 million years ago). It is the most species-rich dinosaur genus with nine to eleven recognized species from fossils found in different regions of modern-day China, Mongolia and Russia. There is also a possible species from Thailand. Psittacosaurus was named by Henry Fairfield Osborn, paleontologist and president of the American Museum of Natural...

Scutellosaurus, meaning "little-shielded lizard," is a genus of herbivorous dinosaur from the Early Jurassic Period of what is now North America (200 to 196 million years ago). It is classified in the sub-order Thyreophora, which include armored dinosaurs. Its closest relative may have been Scelidosaurus, which, unlike the bipedal Scutellosaurus, was mainly quadrupedal. It was one of earliest representatives of Thyreophora. Fossil evidence includes two partial skeletons recovered from...
