Scientists have discovered that a small dinosaur which lived 100 million years ago in northeastern China was covered with course, hairlike fuzz, suggesting that feathers may have evolved much earlier than previously believed.  Although feathers and so-called "dinofuzz" have been previously identified in theropods, two-legged carnivores that are widely believed to be the ancestors of modern birds, the Chinese creature is only remotely related to theropods, and the hollow threads of...

"This juvenile skull indicates that these dinosaurs were still in the midst of that transition," said Laura Porro, a post-doctoral student at the University of Chicago, who...

Berkeley - The fossilized skeleton of a small crocodile relative excavated last year at Petrified Forest National Park in Arizona throws a wrench into theories of how and where the dinosaurs arose more than 210 million years ago at the end of the Triassic Period. The animal, one of many creatures from the Late Triassic known only from their teeth, was thought to be an ancestor of the plant-eating ornithischian dinosaurs like Stegosaurus and Triceratops, which roamed the world millions of...

Yinlong, meaning "hidden dragon," is a genus of ceratopsian dinosaur from the Late Jurassic Period of what is now central Asia. A team of American and Chinese paleontologists -- Xu Xing, Catherine Forster, Jim Clark, and Mo Jinyou -- described and named Yinlong in 2006. Its name is in fact a reference to the movie "˜Crouching Tiger, Hidden Dragon,' large portions of which were filmed in Xinjiang, near the area where the fossil remains of Yinlong were discovered. The type species, Y....

Othnielia is a genus of hypsilophodont dinosaur from the Oxfordian-Tithonian age of the Late Jurassic Period. Several remains have been discovered in the Morrison Formation in the North American states of Wyoming, Utah and Colorado. But, according to revisions made on Morrison ornithischians, the only definite remains are that of a femur belonging to the type species Othnielia rex, named by Peter Galton in 1977. Othnielia was named for its original describer, famed 19th century...

This herbivorous dinosaur ate mostly plants despite having canines. It was a small ornithischian reaching a total length of 3 feet. It had a long, narrow pelvic bone which was like more advanced ornithischians....
