dinosaurs shrank to become birds
2014-08-01 05:21:11

redOrbit Staff & Wire Reports - Your Universe Online The grand mystery over how massive, carnivorous dinosaurs gave rise to flying birds has a simple solution, as it turns out – the meat-eaters simply kept shrinking and shrinking over a period of 50 million years, according to research appearing in Friday’s edition of the journal Science. In their paper, an international team of scientists from the South Australian Museum, the University of Adelaide School of Earth and...

redOrbit Staff & Wire Reports - Your Universe Online 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. The fossils were discovered in Siberia and belong to a species identified as Kulindadromeus zabaikalicus, according to Dan Vergano of National Geographic. The...

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...

New Discovery Reveals Insight Into Feathers, Flight Of Archaeopteryx
2014-07-04 09:52:11

redOrbit Staff & Wire Reports - Your Universe Online Long believed to be one of the first-ever birds, a new Archaeopteryx species has provided additional evidence that feathers evolved long before creatures gained the ability to fly, according to research published online Wednesday in the journal Nature. Researchers from the Ludwig Maximilian University of Munich and the Bavarian State Collections of Paleontology and Geology in Munich, Germany found that the newest specimen of the...

Evolution Of Smaller Dinosaurs Helped Their Lineage Survive As Birds
2014-05-07 09:53:08

Brett Smith for redOrbit.com - Your Universe Online While dinosaurs may have disappeared from the face of the Earth, their lineage has survived in the form of birds and new research published in the journal PLOS Biology has found that both dinosaurs and birds evolved into smaller and smaller sizes – potentially contributing to their success. “Dinosaurs aren't extinct; there are about 10,000 species alive today in the form of birds,” said study author Roger Benson, a paleobiologist...

Microraptor Paraves Fossil
2014-02-24 05:41:20

University of Bristol The key characteristics of birds which allow them to fly – their wings and their small size – arose much earlier than previously thought, according to new research from the Universities of Bristol and Sheffield into the Paraves, the first birds and their closest dinosaurian relatives which lived 160 to 120 million years ago. Mark Puttick and colleagues investigated the rates of evolution of the two key characteristics that preceded flight: body size and...

Bird Fingers: Understanding Evolution Of Wings In Our Avian Friends
2014-01-08 08:29:58

Brett Smith for redOrbit.com - Your Universe Online While birds’ three fingers appear analogous to our own thumb, index and middle fingers, embryonic evidence has shown that the “pinky” side of a bird’s claw develops first, which some theories have said is evidence of the three bird fingers being an index, middle and ring finger. According to a new study published in the Journal of Experimental Zoology, as dinosaurs evolved into birds, they actually lost their pinky and thumb,...

Fossilized Toe Prints Identified As Belonging To Large Ancient Bird
2013-10-28 13:20:31

Lee Rannals for redOrbit.com - Your Universe Online Scientists, publishing a paper in the journal Palaeontology, say two fossilized footprints found in Australia are most likely the oldest known bird tracks in the country. The researchers said the thin-toed tracks in fluvial sandstone were most likely made by two individual birds that were the size of a great egret or a small heron. These ancient birds would have lived during the Early Cretaceous period. "These tracks are evidence...

Understanding Origins Of Flight With Wind Tunnel
2013-09-18 10:40:09

[ Watch The Video: Wind Tunnel Helps Understand Bird Flight ] Michael Harper for redOrbit.com - Your Universe Online Recent research has uncovered the evolutionary origin of birds, as the limbs of certain dinosaurs transformed into wings and gave these creatures the ability to fly. Scientists at the University of Southampton have taken this research one step farther and now say they understand how feathered dinosaurs developed the ability to use these wings for flight. For years...

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...

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...
