Giant prehistoric sand worm fossils discovered

Fossil evidence of a completely unknown prehistoric species of giant sand worm has been discovered in Devon, England. The giant worms would have lived 260 million years ago, long before dinosaurs roamed the Earth, growing up to 3ft long and 6in wide. Large burrow holes were found indicating that the creatures would have travelled beneath the surface."Scientists have found evidence of a giant prehistoric sand worm in an Eng...

Fossil of dinosaur-skin traces found

Workers at a leisure facility found a fossil containing traces of dinosaur skin patterns, a rare discovery that could shed light on the actual appearance of the creature, the Fukui Prefectural Dinosaur Museum said Thursday. Museum officials said classifying the dinosaur has been difficult because fossils of its bones have not been found. But they said it could be a plant-eater from the early Cretaceous Period, about 100 million to 140 million years ago, judging from the age of the stratum where ...

Baby mammoth discovery unveiled

A baby mammoth unearthed in the permafrost of north-west Siberia could be the best preserved specimen of its type, scientists have said. The frozen carcass is to be sent to Japan for detailed study. The six-month-old female calf was discovered on the Yamal peninsula of Russia and is thought to have died 10,000 years ago. The animal's trunk and eyes are still intact and some of its fur remains on the body. Mammoths are an extinct member of the elephant family. Adults often possessed long...

Protein links T. rex to chickens

Submitted by Waspie Dwarf: Protein extracted from 68 million-year-old T. rex bones has shed new light on the evolutionary link between dinosaurs and birds. Researchers compared organic molecules preserved in the T. rex fossils with those of living animals, and found they were similar to chicken protein. The discovery of protein in dinosaur bones is a surprise - organic material was not thought to survive this long. A US team of researchers have published the finding in Science journal. The team ...

Walking with dinosaurs (and humans) ?

First appearing approximately 230 million years ago colossal creatures known as ‘dinosaurs’ ruled the earth. For millions of years, no other animal species legitimately threatened the existence of dinosaurs. Nonetheless, on one unlucky day, approximately 65 million years ago, the dinosaurs seemingly disappeared from the face of the earth or so the story goes…On occasion throughout history, there have been sightings from remote regions of the world of enormous creatures that resemble various dino...

Human ancestor was not so brainy

Submitted by Pandora: A monkey-like animal seen as an ancestor of monkeys, apes and humans was not as brainy as expected, according to scientists who analyzed its nicely preserved 29-million-year-old skull. The finding indicated that primate brain enlargement evolved later than once thought, the researchers said on Monday.They analyzed a remarkably well-preserved fossilized skull of the little primate Aegyptopithecus zeuxis, which lived in the trees and ate fruit and leaves about 29 million year...

Comet may have doomed mammoths

There's a new extraterrestrial suspect in the mysterious, highly debated disappearance of the woolly mammoth some 12,900 years ago. A team of two dozen scientists say the culprit was likely a comet that exploded in the atmosphere above North America. The explosions sent a heat and shock wave across the continent, pelted the ground with a layer of telltale debris, ignited massive wildfires and triggered a major cooling of the climate, said nuclear analytic chemist Richard Firestone of Lawrenc...

Massive Birdlike Dinosaur Unearthed in China

The remains of a huge beaked dinosaur with the looks of an ostrich but the weight of a rhino have been discovered in China's Gobi desert, fossil hunters have announced. The previously unknown dinosaur weighed in around 1.5 tons (1.4 metric tons) and stood more than 16 feet (5 meters) tall—an extraordinary size given its birdlike appearance, say the Chinese researchers who found it. (See a photo gallery of the giant dinosaur. Gigantoraptor erlianensis, which lived some 70 million yea...
