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 ...

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 - 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 ...

Walking with Dinosaurs is a 1999 six-part television series produced by the BBC and narrated by Kenneth Branagh (UK version, BBC) and Avery Brooks (US version, Discovery Channel). The series used computer-generated imagery and animatronics to recreate the life in the Mesozoic, and showed dinosaurs in a way that was only shown before in Jurassic Park, six years earlier. The series was a commercial and scientific success. Dinosaur paleontologists, like Peter Dodson, Peter Larson and James Farlow were scientific advisors. Their influence in the filming proce ...

Feathers are one of the epidermal growths that form the distinctive outer covering, or plumage, on birds. They are the outstanding characteristic that distinguishes the Class Aves from all other living groups. Other Theropoda also had feathers (see Feathered dinosaurs). Feather - Characteristics. Feathers are among the most complex structural organs found in vertebrates: integumentary appendages, formed by controlled proliferation of cells in the epidermis, or outer skin layer, that produce keratin proteins ...

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 ...

Over a hundred distinct anatomical features are shared by birds and theropod dinosaurs. A recent case in point: "Archaeopteryx, therefore, is closely related to the theropods. This in turn means that theropod dinosaurs are the ancestors of the modern birds that followed Archaeopteryx. The find, according to Mayr, 'not only provides further evidence for the theropod ancestry of birds, but it blurs the distinction between basal [the earliest] birds and basal deinonychosaurs,' their fearsome-clawed ancestors. 'I do think that the question of a ...

Shortly after the 1859 publication of Charles Darwin's The Origin of Species, British biologist and evolution-defender Thomas Henry Huxley proposed that birds were descendants of dinosaurs. He cited skeletal similarities, particularly between some saurischian dinosaurs, fossils of what was considered the "first bird," Archaeopteryx, and modern birds. In 1868 he published "On the Animals which are Most Nearly Intermediate between Birds and Reptiles," making the case; but the leading dinosaur expert of the time, Richard Owen, disagreed, claiming Archaeop ...

A number of non-avian dinosaurs are now known to have been feathered. Direct evidence of feathers exists for the following genera: Sinosauropteryx, Dilong paradoxus, Shuvuuia, Yixianosaurus, Beipiaosaurus, Caudipteryx, Protarchaeopteryx, Pedopenna, Microraptor (Cryptovolans), Sinornithosaurus, Jinfengopteryx, Epidendrosaurus (Scansoriopteryx). At present, the most primitive (known) feathered dinosaur is Sinosauropteryx (Jurassic/Cretaceous, 150-120 mya), whose body was covered with feather-like structures that look like hollow ...

After a century of hypotheses without hard evidence, beautifully preserved - and legitimate - fossils of feathered dinosaurs were discovered during the 1990s and 2000s. The fossils were preserved in a Lagerstätte — a sedimentary deposit exhibiting remarkable richness and completeness in its fossils — in Liaoning, China. The area had repeatedly been smothered in volcanic ash produced by eruptions in Inner Mongolia 124 million years ago, during the early Cretaceous. The fine-grained ash preserved the living organisms that it buried in ext ...

Dinosaurs are divided into two major orders, the Saurischia and the Ornithischia, on the basis of hip structure. Cladograms and phylogenetic definitions in this scheme are based primarily on those in The Dinosauria, Second Edition (ed. Weishampel, Dodson & Osmolska, 2004). The symbol + between taxa should be read as indicating a node-based clade defined as comprising all decendants of the last common ancestor of the "added" taxa; the symbol > ("greater than") should be read as indicating a stem-based taxon comprising all organisms shari ...

An iguanodon egg is stolen from its nest by an oviraptor, which starts it on a journey that ends it up an Lemur Island, an island inhabited by lemurs and other creatures. The baby iguanodon Aladar soon emerges from the egg, to the fear and delight of the tiny mammals. The lemurs are initially cautious about the dinosaur, but they nonetheless take him in and raise him. Not long after Aladar has grown up, disaster strikes. A tremendous meteorite falls from the sky, landing in the ocean. The resulting fiery shockwave destroys Lemur Island, but Ala ...
