The distribution of birds in the United States today will probably look very different in 60 years as a result of climate, land use and land cover changes.
Recently launched by Appersian, World Of Dinosaurs is the comprehensive dinosaur resource for iOS and features original HD Illustrations, Dolby audio, and a wealth of scientifically verified information
A fossilized skull discovered in Madagascar belongs to a previously unknown groundhog-like creature that lived alongside dinosaurs and is the largest known mammals of its era, according to research published Wednesday in the journal Nature.
Researchers have located fossil evidence of an amphibious ichthyosaur, a discovery that for the first time links the dolphin-like ichthyosaur to its terrestrial ancestors and is reported in the November 5 advance online edition of the journal Nature.
Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species
University of Bonn researchers postulate: Dinosaurs’ color vision sheds light on the origin of feathers.
The scientific community has accepted the idea that birds evolved from a branch of the dinosaur tree. What evolutionary biologists haven't figure out, however, is how wrists evolved from straight to bent and hyperflexible.
The early stages of the process through which birds evolved from dinosaurs was slow and gradual, and there was no single “missing link” separating the two different types of creatures, according to research published in Thursday’s edition of the journal Current Biology.
How did the earliest birds take wing? Did they fall from trees and learn to flap their forelimbs to avoid crashing? Or did they run along the ground and pump their “arms” to get aloft?
A team of researchers led by Jahan Ramezani of MIT’s Department of Earth, Atmospheric and Planetary Sciences has discovered evidence that dinosaurs lived in North America millions of years earlier than previously suggested.
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, 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...
