Main article: Feathered dinosaurs Although birds use feathers primarily for flight, several dinosaurs have been discovered with feathers on their limbs that would not have functioned for flight. One theory is that feathers originally developed on dinosaurs as a means of insulation; those small dinosaurs that then grew longer feathers may have found them helpful in gliding, which would have begun the evolutionary process that resulted in some proto-birds like Archaeopteryx and Microraptor zhaoianus. Other dinosaurs ...

The single white feather as a symbol of cowardice derives from cockfighting and the belief that a cockerel sporting a white feather in its tail is likely to be a poor fighter. Pure-breed gamecocks don't show white feathers, so its presence indicates that the cockerel is an inferior cross-breed. The symbol is particularly recognised within the British army and in countries associated with the British Empire since the 18th century. White feather - The Four Feathers.

Archaeopteryx lithographica (ahr-kee-OP-ter-ix) meaning "ancient wing", because it resembled an ancient bird (Greek archaio = ancient + pteryx = wing), refers to a Jurassic fossil with both bird and dinosaur features, and is widely accepted as the earliest and most primitive known bird. The discovery of the first intact specimen in 1861, two years after Charles Darwin published The Origin of Species, set off a firestorm of debate about evolution and the ro ...

Dinosaurs are vertebrate animals that range from reptile-like to bird-like.[1] Dinosaurs dominated the terrestrial ecosystem for over 160 million years, first appearing around 230 million years ago. 65 million years ago, at the end of the Cretaceous period, all non-avian dinosaurs became extinct.

The technology of atmospheric reentry was a consequence of the Cold War. Ballistic missiles and nuclear weapons were legacies of World War II left to both the Soviet Union and the United States.

Coelurosauria is a group of theropod dinosaurs that includes the subgroups Tyrannosauridae, Ornithomimidae, and Maniraptora. Coelurosaur characteristics include an extended sacrum, a distally stiffened tail and a bowed ulna. The tibia is also characteristically longer than the femur in coelurosaurs. Recent fossil evidence shows that some coelurosaurs were feathered, and it is conceivable (and indeed the most parsimonious hypothesis) that feathers may have been a feature of the entire group. Most coelurosaurs are bipedal ...
