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 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 Hence dinosaur is sometimes used colloquially as a metaphor for people and things that are perceived to be out of date or no longer in touch with the spirit of the times, and therefore ought to be extinct.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" ...

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 ...

The impact of SL9 highlighted Jupiter's role as a kind of "cosmic vacuum cleaner" for the inner solar system. Studies have shown that the planet's strong gravitational influence leads to many small comets and asteroids colliding with the planet, and the rate of cometary impacts on Jupiter is thought to be between two and ten times higher than the rate on Earth [14] If Jupiter were not present, these small bodies could collide with the inner planets instead. The extinction of the dinosaurs at the end of the Cretaceous period ...

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 ...

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 ...

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 ...

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

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 ...
