Fossil experts say the stunning remains of a "four-winged" dinosaur have confirmed that birds owe their ancestry to two-footed dinosaurs that lived millions of years ago, AFP reported. The well-preserved fossil of a bird-like dinosaur called Anchiornis huxleyi may be the deciding factor, according to Xing Xu of the Chinese Academy of Science in Beijing. Based on incomplete fossils, A. huxleyi was thought to have been a near contemporary of Archaeopteryx, the first recognized bird, which flew...

About 150 million years ago, an evolutionarily hybrid creature, a dinosaur on its way to becoming a bird, died in what is now Germany, and become fossilized in limestone. About 150 years ago, the fossil of this "dinobird" was discovered and celebrated as proof of Charles Darwin's new theory of evolution. Now fast forward to a few weeks ago: The famous fossil, the Thermopolis specimen of Archaeopteryx lithographica, made its way by truck from the Wyoming Dinosaur Center to the Stanford...

According to researchers, brainpower may have enabled birds to survive in the midst of mass extinction. Dinosaurs were wiped out during the Cretaceous-Tertiary mass extinction 65 million years ago, but birds were able to survive and thrive. Recent analysis of fossil skulls using computer tomography scans shows that modern birds were able to survive the dire conditions due to their well-developed brains. The birds' ability to solve problems gave them a crucial edge. "Birdbrained is a dreadful...

New British research finds that the Archaeopteryx lithographica seems to have been more like a bird than a reptile in terms of hearing ability. The researchers based their conclusion on their discovery that the length of a part of the inner ear of reptiles and birds can help predict their hearing ability. The team examined whether the length of the cochlear duct, which lies in the inner ear and is part of the cochlea, could be used to deduce hearing ability in a group of modern birds and...

New research from the University of Calgary and the Royal Tyrrell Museum in Alberta, Canada, finds that the Tyrannosaurus rex tops the list of carnivorous dinosaurs when it comes to sense of smell. The scientists examined the size of the dinosaurs' olfactory bulbs, a part of the brain that regulates smell, using CT scans and measurements of fossilized skulls for a number of meat-eating dinosaurs known as Theropods.  They discovered that the Tyrannosaurus edged out all the other...

The fossilized remains of a dinosaur about the size of a pigeon that may be the ancestor of birds has been discovered by archeologists in China. Scientists recovered 90 percent of the skeleton which was preserved in rock found in Ningcheng county in Inner Mongolia of northern China. The find was reported in an article in Nature. It has four limbs which lacked contour feathers that could be used for flight, making it a flightless creature. It probably live 176 to 146 million years ago in...

The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE, October 3, by Alexander Vargas and colleagues at Yale University, the University of Wisconsin-Madison and Yale Peabody Museum of Natural History. Bird wings only have three fingers, having evolved from remote ancestors that, like humans and most reptiles, had five fingers. Biologists have typically used embryology to identify the evolutionary origin (homology)...

Remains of Cretaceous 'anteater' found during Albertosaurus dig reveal new species of tiny dino An unusual breed of dinosaur that was the size of a chicken, ran on two legs and scoured the ancient forest floor for termites is the smallest dinosaur species found in North America, according to a University of Calgary researcher who analyzed bones found during the excavation of an ancient bone bed near Red Deer, Alberta. "These are bizarre animals. They have long and slender legs, stumpy arms...

Regarding Elliott Epstein's June 8 column, "No evolution in this debate," I believe the religion that conflicts with science is evolution. In true science, a theory is proposed to explain available evidence. Rigorous testing will expose bad theory. Evolution has been discredited but lives on in spite of contradicting evidence and its violation of fundamental principles of science. "Widely accepted" means nothing - it was once widely accepted that the sun revolved around the Earth. The...

By Faux, Cynthia Marshall Padian, Kevin Abstract.- An extreme, dorsally hyperextended posture of the spine (opisthotonus), characterized by the skull and neck recurved over the back, and with strong extension of the tail, is observed in many well-preserved, articulated amniote skeletons (birds and other dinosaurs, pterosaurs, and at least placental mammals). Postmortem water transport may explain some cases of spinal curvature in fossil tetrapods, but we show how these can be distinguished...

John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American Paleontologist who was greatly influential in the revival of scientific research on Dinosaurs. He is best known for demonstrating that Dinosaurs were less like contemporary reptiles but more closely related to large, flightless birds like the ostrich – a theory that holds its ground in the paleontological community to this day. John Ostrom was born and raised in Schenectady, New York. His father was a physician, and...

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,...

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...
