redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Colorado claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet´s species. According to Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences (CIRES) and colleagues, the firestorm...

April Flowers for redOrbit.com - Your Universe Online The last region on Earth to be colonized by humans was home to more than 1,000 species of birds that went extinct shortly after people reached their island homes, new research from the Zoological Society of London (ZSL) and collaborators reveals. Tropical Pacific Islands, like Hawaii and Fiji, were an untouched paradise almost 4,000 years ago when the arrival of the first people caused irreversible damage with overhunting and...

Comet May Have Caused Chicxulub Crater And Dinosaur Extinction
2013-03-24 05:34:56

Brett Smith for redOrbit.com - Your Universe Online One of the most popular theories on the disappearance of the dinosaurs surrounds the 110 mile-wide Chicxulub crater in Mexico. Many scientists believe the extinction was caused by an asteroid that crashed into Earth, leaving only a massive crater behind. However, a group of American scientists is presenting a theory that the culprit was actually a speeding comet, not a relatively slow-moving asteroid as many theories assert....

WATCH VIDEO: [Ancient Crocs And Their Prey] Brett Smith for redOrbit.com - Your Universe Online By catching an ancient reptile with its ℠hand in the cookie jar,´ paleontologists were able to identify a relationship between a predator and a previously unknown species of dinosaur that it preyed upon. According to a report in the open-access journal PLoS ONE, a group of American researchers has discovered a new species of herbivorous dinosaur that was preyed upon by...

Evidence Supports Dinosaur Extinction Level Event
2013-02-07 19:14:22

Alan McStravick for redOrbit.com — Your Universe Online We´ve had an increasing fascination with comets and asteroids over the past several years. We´ve fictionally sent a rogue group of astronauts to detonate one of these heavenly travelers. We´ve seen the disastrous effect of a potential impact in both movies and on television. We´ve elevated our global anxiety tracking the trajectory of these large, quickly moving celestial bodies. And it seems our vigilance...

Research Suggests Eurasian Jays May Be Able To Determine Aspects Of The 'Internal Life' Of Their Mate
2013-02-04 19:51:10

University of Cambridge New research shows that male Eurasian Jays in committed relationships are able to share food with their female partner according to her current desire. The behavior suggests the potential for 'state-attribution' in these birds — the ability to recognize and understand the internal life and psychological states of others. The research was carried out in Professor Nicola Clayton's Comparative Cognition lab at Cambridge University's Department of...

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....

Dinosaurs May Have Shaken Tail Feathers In Elaborate Mating Display
2013-01-07 14:42:34

Alan McStravick for redOrbit.com - Your Universe Online This week University of Alberta researchers examining the fossilized remains of dinosaur tail bones made what appears to be a startling discovery. Our modern day birds like the turkey and the peacock, which often use their dazzling plumage to attract a mate, may be channeling their long-departed ancestors: the feathered dinosaurs. This discovery was not made in a single find, however. Scott Persons, a paleontologist at the...

Fossil Bird Discovered With Teeth For A Tough Diet
2013-01-07 11:02:26

Alan McStravick for redOrbit.com - Your Universe Online A trip to the Galapagos islands will bring you face to face with 14 closely related species of finch that Charles Darwin discovered on his adventure abroad in the 1830s. The finches he noted, still referenced in essentially every biology textbook, had beak sizes of varying lengths and sizes. This was true of both the ground- and tree-dwelling birds, and Darwin postulated that differing diets might have required the birds´ unique...

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...

Robert Thomas Bakker (born March 24, 1945) is an American Paleontologist known for his contribution to the “Dinosaur Renaissance” and his support of his mentor Ostrom’s theory that some dinosaurs were warm-blooded. He specializes in the ecological context and behavior of dinosaurs. Bakker was born in Bergen County, New Jersey. As a young boy, he developed an interest in dinosaurs following his first trip to the dinosaur exhibit at the American Museum of Natural History – he was...

Ornithology
2013-10-09 12:32:30

Ornithology, a branch of zoology, is the study of birds. The term ornithology is derived from the ancient Greek words for bird and rationale or explanation. This study differs from other sciences because amateurs often take part in studies and because birds are commonly seen. It is thought that ornithology developed in the same manner than biology developed. Drawings from the Stone Age show the earliest interest in birds and the remains of over eighty bird species have been found at excavated...
