Latest Origin of birds Stories
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.
Researchers at Oregon State University have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight â€“ and the finding means it's unlikely that birds descended from any known theropod dinosaurs.
A team of researchers led by a North Carolina State University scientist has found soft tissue on a dinosaur skeleton. The team was led by Professor Mary Schweitzer, who in 2005 found soft tissue in the fossilized bone of a 68-million-year old Tyrannosaurus rex, The (Raleigh, N.C.) News & Observer reported Thursday. The findings will be published this week in the journal Science. As was the case with the T.
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.
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.
Early dinosaurs were likely to have used their feathers for looks rather than for flight or staying warm, researchers reported on Monday.
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.
By Perkins, Sid New study questions analyses of T. rex remains Three years ago, a team of scientists rocked the paleontology world by reporting the recovery of flexible tissue resembling blood vessels from a 68- million-year-old dinosaur fossil.
By Dan Vergano New research is challenging claims made three years ago that scientists had discovered soft tissue remnants in the thighbone of a Tyrannosaurus fossil.
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...
Protarchaeopteryx, meaning "before Archaeopteryx," is a genus of feathered theropod dinosaur from the Aptian age of the Early Cretaceous Period (124 million years ago). It was found in the Jianshangou bed of the Yixian Formation in what is now China. It was most likely more primitive than Archaeopteryx, making it a non-avian theropod dinosaur rather than a true avian bird. Protarchaeopteryx was about 3.3 feet in length, making it larger than Archaeopteryx. It had symmetrical feathers on...
Citipati, meaning "funeral pyre lord", is a genus of theropod dinosaur from the Late Cretaceous Period of what is now Mongolia. It is known from the Djadokhta Formation in the Gobi Desert. It is one of the best known oviraptorids thanks to a number of well preserved fossils, some of which have been found in brooding positions on top of egg nests. These findings help solidify the link between non-avian dinosaurs and birds. It was first described by James M. Clark, Mark Norell, and Rinchen...
Anchiornis, meaning "near bird", is a genus of small, feathered dinosaur. The type species A. Huxleyi is named in honor of Thomas Henry Huxley, a scientist known for his early studies in the biological evolutionary relationship between birds and dinosaurs. The type specimen was described by paleontologist Xu Xing in 2008. The remains of Anchiornis were discovered in western Liaoning, China in sedimentary lake deposits. The age of the dinosaur is uncertain, but it is likely that it lived...
