The sudden mass extinction of the non-avian dinosaurs, which occurred around 65 million years ago, is one of the most intriguing mysteries in paleontology. Many other groups of animals also became extinct at this time, including ammonites (nautilus-like mollusks), mosasaurs, plesiosaurs, pterosaurs, herbivorous turtles and crocodiles, most birds, and many groups of mammals.[32] The nature of the event which caused this mass extinction has been extensively studied since the 1970s. At present, several related th ...

Dinosaur - Warm-blooded?. A vigorous debate on the subject of temperature regulation in dinosaurs has been ongoing since the 1960s. Originally, scientists broadly disagreed as to whether dinosaurs were capable of regulating their body temperatures at all. More recently, dinosaur endothermy has become the consensus view, and debate has focused on the mechanisms of temperature regulation. After dinosaurs were discovered, paleontologists first posited that they were ectothermic creatures: "terrible lizards" a ...

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. Dinosaurs still exist today in the line of birds (avian dinosaurs). Knowledge about dinosaurs is derived from both fossil and non-fossil records, includ ...

A wide range of organisms became extinct at the end of the Cretaceous period. The most conspicuous, of course, were the dinosaurs. While there is evidence that dinosaur diversity declined in the Late Cretaceous of North America, many species are known from the Hell Creek and Lance Formations of the Late Cretaceous. These include six or seven families of theropods and a similar number of ornithischians. Among the Dinosauria, the only survivors were the birds, but birds suffered heavy losses. A number of diverse groups became extinct, includin ...

Cretaceous-Tertiary extinction event - Alvarez hypothesis. In 1980, a team of researchers led by Nobel-prize-winning physicist Luis Alvarez, his son, geologist Walter Alvarez, and a group of colleagues discovered that fossilized sedimentary layers found all over the world at the Cretaceous-Tertiary boundary, 65.5 million years ago contain a concentration of iridium hundreds of times greater than normal. The end of the Cretaceous coincided with the end of the dinosaurs. It was in general a period of extraordinary ...

Asteroid deflection strategies - Nuclear weapons. One of the most often proposed solutions is firing nuclear missiles at the oncoming asteroid to vaporize all or most of it. While today's nuclear weapons are not powerful enough to destroy a 1 km asteroid, theoretically, thermonuclear weapons can be scaled up to any size so long as enough raw materials are available. If not completely vaporised, the resulting reduction of mass from the blast combined with the radiation blast could produce positive results. The lar ...

Any deflection effort would require the object in question to be identified years in advance of the projected impact, allowing for expenditure of sufficient time and resources to build a slow-pusher device or an explosive device unlike any currently existing. Don Yeomans, manager of NASA's Near Earth Object Monitoring program, said that 10 years or more of advance warning would be needed for it to be pract ...

Asteroid deflection strategies - Formation of Moon. It has been theorised that Earth collided with a 'Mars' sized object in its early development, effectively creating the moon. Another theory is that once there was a planet between Mars and Jupiter where now there is an asteroid belt in which some of the pieces flew outward, contributing to excentric orbits of the outer planets, and unusual sizes of some moons, relative to their planets, including that of Earth.

Asteroid or comet impacts are a common subgenre of disaster fiction, and such stories typically feature some attempt - successful or unsuccessful - to prevent the catastrophe. Most involve trying to destroy or explosively redirect an object, perhaps understandably from the direction of dramatic interest. Science Fiction authors Charles Sheffield and Arthur C. Clarke (Sunstorm) have also written of a "cosmic bullet" extraterrestial intelligence threat consisting of a projectile aimed at our sun at near light speed. In the openin ...

Dinosaur - Definition. The superorder or clade "Dinosauria" was formally named by the English scientist Richard Owen in 1842. The term is a portmanteau derived from the Greek words deinos ("terrible" or "fearfully great" or "formidable") and sauros ("lizard" or "reptile"). Owen chose it to express his awe at the size and majesty of the extinct animals, not out of fear or trepidation at their size ...

Information on dinosaurs is obtained from a widely varying fields of study which include Physics, Chemistry, Biology, and the Earth Sciences (which also includes Paleontology). Activities include the discovery, reconstruction and conservation of dinosaur fossils and the interpretation of those fossils which enables us to better understand the evolution, classification and behavior of dinosaurs.

Dinosaur fossils have been known of for millennia, although their true nature was not recognized; the Chinese considered them to be dragon bones, while Europeans believed them to be the remains of giants and other creatures killed by the Great Flood. The first dinosaur species to be identified and named was Iguanodon, which was discovered in 1822 by the English geologist Gideon Mantell, who recognized similarities bet ...

Dinosaurs were highly successful creatures; they were the dominant land animals on Earth for over 150 million years. However, it is their sudden extinction as much as their success that has made them an enduring part of human popular culture. Hence dinosaur is sometimes used colloquially as a metaphor for people and things that are perceived to be out of date or no longer in touch with the spirit of the times, and therefore ought to be extinct. For example, members of the punk movement derided the "progressive" ...

Dinosaur - Warm-blooded?. Scientists have waged an ongoing and vigorous debate over temperature regulation in dinosaurs, at first over its possibility, and then over its method. This thermoregulation debate was first popularized by Robert T. "Bob" Bakker. After dinosaurs were discovered, paleontologists first posited that they were ectothermic creatures: "terrible lizards" as their name suggested. This supposed cold-bloodedness implied that dinosaurs were mostly slow, sluggish organisms, comparable to modern reptil ...
