The group identified the color of the raven-sized creature's fossilized wing feather, determining it was black. The color and the structures that supplied the pigment suggest that Archaeopteryx's feathers were rigid and durable, which would have helped it to fly.

Until now, remains of sauropoda had been recovered from all continental landmasses, except Antarctica. The identification of the remains of the sauropod dinosaur suggests that advanced titanosaurs achieved a global distribution at least by the Late Cretaceous.

Researchers collected two gigantic vertebrae and a femur in New Mexico. The bones belong to the sauropod dinosaur Alamosaurus sanjuanensis: a long-necked plant eater related to Diplodocus. The Alamosaurus roamed what is now the southwestern United States and Mexico about 69 million years ago.

The animal, named Spinops sternbergorum, lived approximately 76 million years ago in southern Alberta, Canada. Spinops was a plant-eater that weighed around two tons when alive, a smaller cousin of Triceratops.

Researchers have found that Madagascar dinosaurs carried giant, hollow bones in their skin that may have helped them survive the harsh environments they inhabited. This discovery has shed new light on the anatomy and function of these bones in the biggest animals to ever walk on land.

Carnotaurus was a seven-meter-long predator with a huge tail muscle that paleontologists say made it one of the fastest running hunters of its time.

Their terrifying image has been popularized in part because members of this group possess a greatly enlarged talon on their foot -- analogous to a butcher's hook. Yet the function of the highly recurved claw on the foot of raptor dinosaurs has largely remained a mystery to paleontologists. Scientists have now unveiled a new species of raptor dinosaur discovered in southern Utah that sheds new light on this and several other long-standing questions in paleontology, including how dinosaurs evolved on the "lost continent" of Laramidia (western North America) during the Late Cretaceous -- a period known as the zenith of dinosaur diversity.

The resin turned to resilient amber, preserving some 80 million-year-old protofeathers, possibly from non-avian dinosaurs, as well as plumage that is very similar to modern birds, including those that can swim under water.

It is the youngest nodosaur ever discovered, and a founder of a new genus and species that lived approximately 110 million years ago during the Early Cretaceous Era. Nodosaurs have been found in diverse locations worldwide, but they've rarely been found in the United States.

The finding indicates that dinosaurs did not go extinct prior to the impact and provides further evidence as to whether the impact was in fact the cause of their extinction.

It depends largely on whether they were cold or warm blooded. Now, a team of researchers has developed a new approach to take body temperatures of dinosaurs for the first time, providing new insights into whether dinosaurs were cold or warm blooded.

If the reptile is pteranodon, it would be the first of its kind discovered as far south as Texas within the ancient Western Interior Seaway.

Brontomerus may have used its powerful thighs as a weapon to kick predators, or to help travel over rough, hilly terrain. Brontomerus lived about 110 million years ago, during the Early Cretaceous Period, and probably had to contend with fierce "raptors" such as Deinonychus and Utahraptor.

A new census of dinosaurs in Montana's Hell Creek Formation shows that T. rex was far too abundant to be a top predator. Paleontologists argue that T. rex probably subsisted on a broad variety of dead as well as live animals, much like today's hyena.

They represent the oldest embryos of any land-dwelling vertebrate ever found. The eggs, found in 1976 in South Africa, date from the early part of the Jurassic Period, 190 million years ago. They belong to Massospondylus, a member of a group of dinosaurs known as prosauropods that are the ancestors to the later sauropods -- the large, four-legged dinosaurs with long necks, typified by the popular ' Brontosaurus' and Diplodocus.

Dating from the Late Jurassic, some 148 million years ago, these tracks were made before the Rocky Mountains rose, when the area was a broad savanna full of dinosaurs.

Paleontologists from the United States and Canada have found bite marks on the giants' bones that were made by other T. rex, according to a new study.

With more than 400 bones brought to light, this site is remarkable both for the quantity of discoveries and their state of preservation.

Just one or two million years after the massive Permian-Triassic extinction, an animal smaller than a house cat walked across fine mud in what is now Poland.

Now, researchers have found that dinosaurs had thick layers of cartilage in their joints, which means they may have been considerably taller than previously thought.
