Turtles Began Living in Shells Earlier Than Previously Thought

Peter Suciu for redOrbit.com — Your Universe Online While there are several species that have shells, the turtle is the only animal to form such a shell on the outside of its body through a fusion of modified ribs, vertebrae and shoulder girdle bone. This makes the turtle´s shell a unique modification, one that has fascinated and confounded biologists for more than two centuries. How and when it originated has remained mostly conjecture. However, a team of researchers led...

Lawrence LeBlond for redOrbit.com - Your Universe Online The debate whether dinosaurs went extinct due to a large space rock that struck the Earth 65.5 million years ago (MYA) may have been answered with the discovery of a distinctive brow horn from a Ceratopsian dinosaur just 13 centimeters (5.1 inches) below the K-T boundary -- the distinct layer of geological sediments separating the Cretaceous and Tertiary periods. Rocks laid down 65.5 MYA show a thin layer abundant in rare elements...

By examining the type of rock in which dinosaur fossils were embedded, an often unappreciated part of the remains, scientists have determined that different species of North American dinosaurs from the Late Cretaceous period 65 million years ago occupied different environments separated by just a few miles.Hadrosaurs or duck-billed dinosaurs, along with the small ornithopod Thescelosaurus, preferred to live along the edge of rivers, according to the research. Ceratopsians, on the other hand,...

Researchers at North Dakota's state museum are scrupulously chipping away at a giant greenish-black 65-million-year-old rock, using tiny brushes and chisels to uncover a nearly complete dinosaur fossil, with skin and all.  Named Dakota, the fossil is unlike almost any other ever found, and was unearthed in 2004 in southwestern North Dakota. The Edmontosaurus is covered by fossilized skin that is hard as a rock, and among only a few mummified dinosaurs ever discovered. "This is the...

WASHINGTON -- One of the most complete dinosaur mummies ever found is revealing secrets locked away for millions of years, bringing researchers as close as they will ever get to touching a live dino. The fossilized duckbilled hadrosaur is so well preserved that scientists have been able to calculate its muscle mass and learn that it was more muscular than thought, probably giving it the ability to outrun predators such as T. rex. While they call it a mummy, the dinosaur is not really...
