An international team of researchers has discovered the first-ever fossils belonging to a plant-eating dinosaur that contained both scales and featherlike structures, suggesting that plumage might have been present in a far greater number of species than previously believed.
Newly-discovered fossils belonging to the largest four-winged dinosaur ever found could help shed new light on how the creatures were able to fly, according to research published online Tuesday in the journal Nature Communications.
It has long been perceived that the modern-day bird evolved from the dinosaur millions of years ago. However, new evidence has challenged this common belief.
Over the last two decades, huge numbers of fossils have been collected from the western Liaoning Province and adjacent parts of northeastern China, including exceptionally preserved feathered dinosaurs, early birds, and mammals.
New research that revises the rules allowing scientists to decipher color in dinosaurs may also provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology prior to its origin.
Scientists at the University of Southampton have used a wind tunnel to help understand how early feathered dinosaurs were able to fly.
A new discovery made by paleontologists digging in China has put Archaeopteryx back on the map as one of the earliest birds.
A set of fossil remains discovered in northwestern China back in 2006 have been classified as a new species of carnivorous dinosaur belonging to the same suborder as the Tyrannosaurus rex.
When you inspect the legs of most birds you will find everything from the knee down is scaly rather than feathery. There is an exception to this rule however. Some birds of prey, such as eagles, have more feathering below the knee extending down to the feet.
Researchers examining the fossilized remains of dinosaur tail bones discovered that dinosaurs, like modern-day turkeys and the peacocks, may have shaken their dazzling tail feathers to attract mates.
Sinosauropteryx, meaning “Chinese reptilian wing,” is a genus of theropod dinosaur from the Late Jurassic to the Early Cretaceous Period 135 to 121 million years ago. It was discovered in 1996 by two Chinese farmers in the dry countryside near Liaoning Province, China. The same area has also produced later on other bird-like dinosaur fossils including Caudipteryx and Protarchaeopteryx. Three complete skeletons of Sinosauropteryx have been found, including few samples of protofeathers,...
Microraptor, meaning “small thief,” is a genus of dromaeosaurid dinosaur from the Early Cretaceous Period (120 million years ago). This small, four-winged animal was first discovered in the Jiufotang Formation in Liaoning, China, with more than two dozen specimens unearthed. There are two known species of Microraptor. The type species, M. zhaoianus, has been hotly debated for years. It was initially placed in the genus Archaeoraptor before a more accurate description placed it in the...
Sinornithosaurus, meaning “Chinese bird-lizard,” is a genus of feathered dromaeosaurid dinosaur from the early Aptian age of the Early Cretaceous Period (120 - 125 million years ago). It lived in what is now China and was the fifth non-avian feathered dinosaur discovered by 1999. It was discovered in the Jianshangou beds of the Yixian Formation, from the Sihetun locality of western Liaoning. Xu Xing, Wang Xiaolin and Wu Xiaochun, of the Institute of Vertebrate Paleontology, Beijing are...
Sinocalliopteryx, meaning "Chinese beautiful feather," is a genus of compsognathid dinosaur from the Early Cretaceous Period (124.6 million years ago) from China. It was recovered from the Jianshangou beds of the Yixian Formation. The type species, S. gigas, meaning "giant," was derived from the dinosaur's large size for a compsognathid. It is also unique from other compsognathids, by its relatively long hands in relation to its arms, which were also longer overall than in most...
Scipionyx, meaning "Scipio's claw," and named after Scipione Breislak, is a genus of theropod dinosaur from the Early Cretaceous Period of what is now Italy (113 million years ago). It was discovered in 1981 by amateur paleontologist Giovanni Todesco near Pietraroja, Italy, about 50 miles from Naples. Fossils were preserved in the Pietraroja limestone formation, well known for unusually well-preserved fossils. Todesco thought the fossilized remains were that of a bird. Unaware of the...
