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...

Dinosaurs Took A Middle Road Between Warm- And Cold-Blooded
2014-06-13 09:10:26

Lawrence LeBlond for redOrbit.com - Your Universe Online There has been a long-standing debate over dinosaurs: were they cold-blooded like modern day reptiles or warm-blooded like mammals? In the early days of science, and in Hollywood, these prehistoric beasts were depicted as slow, lumbering giants as they were believed to be cold-blooded. But over the past few decades, these animals have been portrayed as swift-moving lizards, more reminiscent of warm-blooded behaviors. New...

Gerard LeBlond for redOrbit.com - Your Universe Online Forests affected by fires 66 million years ago during the last days of the dinosaurs recovered no differently than they do today, according to a team of researchers from McGill University and the Royal Saskatchewan Museum. The team discovered the first fossil-record evidence of forest fire ecology during an expedition in southern Saskatchewan, Canada, at Grasslands National Park in an area known as the Frenchman Formation around...

New Fossil Evidence Shows Reproductive Changes During Transition From Dinosaurs To Birds
2014-05-30 13:14:34

Brett Smith for redOrbit.com - Your Universe Online Over the course of millions of years, some dinosaurs evolved into the modern birds we see today – and that transition included the shift to a single-ovary reproductive system, according to a new report in the National Science Review journal. The study authors said this change was probably advantageous to flying animals that evolved toward lighter and lighter weights. "The most widely accepted hypothesis for the presence of a...

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...

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...

asteroid impact
2014-04-10 08:39:56

Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

Researchers used brown and black chicken feathers for their study
2014-03-06 07:01:57

April Flowers for redOrbit.com - Your Universe Online It has been proposed by paleontologists who study fossilized feathers that the shapes of certain microscopic structures found inside the feathers might tell us the color of the ancient birds. If these structures are melanosomes, that could be true. A new study, led by North Carolina State University, however, demonstrates that it is not yet possible to tell if the structures are melanosomes, or remnants of ancient bacteria. Found...

Swimming Birds Evolved Rudder-like Tail To Dive For Food
2014-02-27 15:43:42

PLOS The convergent evolution of tail shapes in diving birds may be driven by foraging style, according to a paper published in PLOS ONE on February 26, 2014 by Ryan Felice and Patrick O'Connor from Ohio University. Birds use their wings and specialized tail to maneuver through the air while flying. It turns out that the purpose of a bird's tail may have also aided in their diversification by allowing them to use a greater variety of foraging strategies. To better understand the...

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
