Image 1 - Killer Claws Help Provide New Theory On Evolution Of Flight
2011-12-16 03:57:20

New research from Montana State University's Museum of the Rockies has revealed how dinosaurs like Velociraptor and Deinonychus used their famous killer claws, leading to a new hypothesis on the evolution of flight in birds. In a paper published Dec. 14 in PLoS ONE, MSU researchers Denver W. Fowler, Elizabeth A. Freedman, John B. Scannella and Robert E. Kambic (now at Brown University in Rhode Island), describe how comparing modern birds of prey helped develop a new behavior model for...

Princeton Model Shows Fallout Of Giant Meteorite Strike

Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions. Princeton researchers created the first model to take into account Earth's elliptical shape, surface features and ocean...

Image 1 - Worms Among First Animals To Appear After Asteroid Impact
2011-10-11 12:21:28

University of Colorado researchers have found that worms were among the first animals to surface after an asteroid plowed into the Gulf of Mexico 65.5 million years ago. Geological sciences Associate Professor Karen Chin of the university said this "K-T extinction" is often focused on the survival and proliferation of mammals, and studies show some of the earliest terrestrial ecosystems to emerge were aquatic plants. However, new evidence from North Dakota shows networks of...

Image 1 - Study Finds 'Clear Evidence' Meteorite Wiped Out Primitive Birds

  The same meteorite impact that caused dinosaurs to go extinct 65 million years ago also essentially wiped out ancient birds, a team of paleontologists claim in a new study. The researchers, led by Nicholas Longrich of Yale University, studied collections of approximately two dozen bird fossils of various species from the school's Peabody Museum of Natural History, as well as from the American Museum of Natural History, the University of California Museum of Paleontology, and 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...

Lawrence LeBlond for redOrbit.com - Your Universe Online The debate whether dinosaurs went extinct due to a large space rock that struck the Earth 65.5 million years ago (MYA) may have been answered with the discovery of a distinctive brow horn from a Ceratopsian dinosaur just 13 centimeters (5.1 inches) below the K-T boundary -- the distinct layer of geological sediments separating the Cretaceous and Tertiary periods. Rocks laid down 65.5 MYA show a thin layer abundant in rare elements...

Dinosaur Expert Dr. Phillip Manning Hosts Jurassic C.S.I.: In Living Color, Premiering Thursday, July 7, at 10:00 PM ET/PT WASHINGTON, June 30, 2011 /PRNewswire-USNewswire/ -- Whether predator or prey, sneaking around or strutting before potential mates, dinosaurs likely lived and died by their distinct color patterns. But nobody knows how dinosaurs really looked. Exactly what color patterns did dinosaurs display? A team of scientists are closer to answering that question, reporting...

Scientists have found a way to take the temperature of dinosaurs that have been extinct for millions of years. But since you cannot take their temperature like you do with humans, the researchers did the next best thing -- study dinosaur teeth, which can reflect body temperature. What they found is surprising. Studying the teeth of the long-necked Brachiosaurus, they discovered it had a temperature of about 100.8 degrees F and the smaller Camarasaurus had a temp of 98.3 degrees. Humans...

University of Alberta researchers determined that a fossilized dinosaur bone found in New Mexico confounds the long established paradigm that the age of dinosaurs ended between 65.5 and 66 million years ago. The U of A team, led by Larry Heaman from the Department of Earth and Atmospheric Sciences, determined the femur bone of a hadrosaur as being only 64.8 million years old. That means this particular plant eater was alive about 700,000 years after the mass extinction event many...

Scientists have unveiled fossils of one of the earliest dinosaurs ever discovered -- a petite, nimble carnivore from the late Triassic period some 230 million years ago. Dubbed Eodromaeus, or "dawn runner", the never-before seen species was a small, two-legged creature that may have been among the first dinosaurs to roam the Earth, making them likely ancestors of the famous Tyrannosaurus rex. The scientists reconstructed the dinosaur from a nearly complete set of bones found in Ischigualasto,...

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...
