New Evidence Refutes The 'Birds Evolving From Dinosaurs' Theory
2014-07-11 06:58:58

Gerard LeBlond for redOrbit.com - Your Universe Online It has long been perceived that the modern-day bird evolved from the dinosaur millions of years ago. However, evidence from a new study published in the Journal of Ornithology has challenged this common belief. After re-examining a bird-like fossil from China, it was discovered that it was not a dinosaur as first thought. Instead, it was a tree-climbing animal that could glide, according to researchers Stephen Czerkas from The...

Less Diversity Found In Bird Species Of 125M Years Ago
2014-05-28 11:10:57

Brett Smith for redOrbit.com - Your Universe Online While the typical American wetland hosts a range of birds with different physiologies and behaviors, bird diversity in prehistoric times was significantly lower, according to a new study published in the journal Proceedings of the Royal Society B. "There were no swans, no swallows, no herons, nothing like that. They were pretty much all between a sparrow and a crow," said study author Jonathan Mitchell, an evolutionary biologist at the...

Avian Evolution: How Raptor Limbs Became Bird Wings
2013-09-18 06:09:13

April Flowers for redOrbit.com - Your Universe Online Scientists are certain that sometime around 150 million years ago birds originated from a group of small, meat-eating theropod dinosaurs called maniraptorans. According to recent studies conducted around the world, the maniraptorans were very bird-like, with feathers, hollow bones, small body sizes and high metabolic rates. What remains unclear is at what point the forelimbs evolved into wings, making it possible for the maniraptorans...

Dinosaur Fossil Challenges Bird Evolution Theory
2013-01-25 04:10:05

redOrbit Staff & Wire Reports - Your Universe Online A recently discovered dinosaur fossil believed to pre-date those from which birds were believed to have evolved could drastically change current theories on the origins of flight, according to a new UK study. According to BBC News, the fossil comes from a feathered-but-flightless dinosaur that was less than a foot in length and lived approximately 140 million years ago. The creature, which has been dubbed the Eosinopteryx, would...

How To Tell If An Avian Dinosaur Was Male Or Female
2013-01-23 08:14:54

April Flowers for redOrbit.com - Your Universe Online An international team of paleontologists, including Dr. Luis Chiappe, Director of the Natural History Museum of Los Angeles Country's Dinosaur Institute has discovered a definitive way to determine the sex of an avian dinosaur species. The 125-million-year-old Mesozoic bird, Confuciusornis sanctus, had remarkable differences in plumage between specimens. Some had almost body length ornamental tail feathers, while others had none....

Evidence Links Birds And Dinosaurs
2012-11-21 21:16:27

Lee Rannals for redOrbit.com — Your Universe Online More evidence has emerged, published in the journal Current Biology, claiming birds are the descendants of dinosaurs. The prehistoric Archaeopteryx and bird-like dinosaurs before them had a more primitive version of a wing, according to the recent findings. Scientists are piecing together how the wing evolved, lending to evidence that gliding dinosaurs spent much of their days in the trees. "Before, it seemed that we had...

When Evolving From T-Rex To Sparrow, Timing Is Critical
2012-05-28 08:31:30

Although a sparrow and a Tyrannosaurus Rex might appear to have nothing in common, evolutionary biologists see more that relates the two creatures than not.  A new study, led by Harvard scientists, has shown that modern birds are essentially living dinosaurs with skulls that are remarkably similar to those of their juvenile ancestors. Arkhat Abzhanov, Associate Professor of Organismic and Evolutionary Biology and Bhart-Anjan Bhullar, a PhD student in Abzhanov laboratory and the first...

New Research Shows Feathered Dinosaur Could Fly
2012-01-25 06:22:05

[ Watch the Video ] An international team of researchers led by Brown University has shed some new light on whether the winged dinosaur Archaeopteryx could fly. The team has determined that a well-preserved feather on the raven-sized dinosaur's wing was black, which is evidence that the feathers had traits that could help Archaeopteryx fly. Also, the researchers determined that the fossilized feather's structure is identical to living birds, according to the research published in the...

Archaeopteryx, once believed to be the world's earliest bird, may actually have been just another feathered dinosaur, according to a report published Wednesday in the journal Nature. Researchers in China, led by Xing Xu of Linyi University, carried out a phylogenetic analysis combining a newly discovered fossil with other similar dinosaurs and early birds, and concluded that the species should no longer be considered a fully developed bird. If confirmed, the controversial hypothesis would be...

Scientists' find describes how one family of dinosaurs came to look like birds--independent of birds Through an expedition to the Gobi Desert of China, scientists have solved the puzzle of how one group of dinosaurs came to look like birds--independent of birds. The discovery extends the fossil record of the family Alvarezsauridae--a bizarre group of bird-like dinosaurs with a large claw on the hand and very short, powerful arms--back 63 million years, further distancing the group from birds...
