BERKELEY -- The peculiar pose of many fossilized dinosaurs, with wide-open mouth, head thrown back and recurved tail, likely resulted from the agonized death throes typical of brain damage and asphyxiation, according to two paleontologists. A classic example of the posture, which has puzzled paleontologists for ages, is the 150 million-year-old Archaeopteryx, the first-known example of a feathered dinosaur and the proposed link between dinosaurs and present-day birds. "Virtually all...

By Patricia Reaney LONDON -- A newly discovered, perfectly preserved fossil of a 150 million-year-old dinosaur found in southern Germany may force scientists to rethink how and when feathers evolved. The nearly complete remains of the chicken-size dinosaur named Juravenator, which is described in the journal Nature on Wednesday, were preserved in limestone. But unlike other members of the group of two-legged meat-eating predators known as coelurosaurs, it had no feathers. "It is an absolutely...

WASHINGTON (Reuters) - An especially well-preserved specimen of Archaeopteryx shows the first known bird had feet like a dinosaur -- made not for perching but for running on the ground, scientists said on Thursday. The first toe on the fossil turns inward, similar to a human thumb and most like the hunting dinosaurs known as deinonychosaurs -- notably the Velociraptor with its long claw for disemboweling prey. Gerald Mayr of the Forschungsinstitut Senckenberg in Frankfurt, Germany,...

WASHINGTON -- A new analysis of Archaeopteryx, the earliest known birdlike animal, shows it had feet like dinosaurs - a finding that adds weight to the belief that the birds frequenting backyard feeders today are descendants of mighty ancient carnivores. While not all scientists agree, many consider Archaeopteryx the first bird, since it had wings and was the first fossil found with feathers. Details have been lacking on the animals, however, since only a few fossil specimens have been...

CHAPEL HILL -- No good evidence exists that fossilized structures found in China and which some paleontologists claim are the earliest known rudimentary feathers were really feathers at all, a renowned ornithologist says. Instead, the fossilized patterns appear to be bits of decomposed skin and supporting tissues that just happen to resemble feathers to a modest degree. Led by Dr. Alan Feduccia of the University of North Carolina at Chapel Hill, a team of scientists says that as a result of...

Biologists examining evidence for the claim that birds evolved from dinosaurs have reached some surprising new conclusions. However, they caution that "the problem of avian origins is far from being resolved." Their analysis is published online October 10, 2005 in the Journal of Morphology, published by John Wiley & Sons, Inc. and available via Wiley InterScience (www.interscience.wiley.com/journal/morphology). Dinosaurs have long captured the imagination while their relationships have...

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...
