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...

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....

Dinosaur Abdominal Analysis Reveals Wolf-Like Hunting Prowess

Lawrence LeBlond for redOrbit.com - Your Universe Online Analysis of two dinosaur fossil specimens have revealed new information about hunting and feeding behaviors of a wolf-like dinosaur, according to a report published in the latest issue of PLoS ONE. Researchers from University of Alberta at Edmonton found evidence that a feathered dinosaur known as Sinocalliopteryx was able to capture and consume small flying dinosaurs. Sinocalliopteryx, itself a flightless dinosaur, stood about...

Researchers have uncovered chemical traces of a pigment, an important component of color, that once formed patterns in the feathers of fossilized birds. The pigment is one of the coloring agents responsible for brown eyes and dark hair in many modern species.  This discovery would have been one of the factors that determined the birds' color patterns, along with structural properties of the birds' feathers and other pigments they ingested as part of their diets. The discovery will help...

The earliest birds may have had feathers, but they were not strong enough to carry the winged creatures in flight, researchers revealed Thursday. Recent fossil discoveries show that feathers on some of the early birds, including Confuciusornis and Archaeopteryx, were too weak to support the birds in flight. While modern birds have feathers with a strong central shaft that is hollow to reduce weight, the earliest-known birds had feathers that were much thinner and more frail. Robert Nudds...

The color of some feathers on dinosaurs and early birds has been identified for the first time, reports a paper published in Nature this week. The research found that the theropod dinosaur Sinosauropteryx had simple bristles "“ precursors of feathers "“ in alternate orange and white rings down its tail, and that the early bird Confuciusornis had patches of white, black and orange-brown coloring. Future work will allow precise mapping of colors and patterns across the whole bird....
