Dictionary

Dinosaur : any of a group (Dinosauria) of extinct often very large chiefly terrestrial carnivorous or herbivorous reptiles of the Mesozoic era — Webster

OneLook, Free Dictionary, Wiktionary, Urban Dictionary

Encyclopedia

Dinosaurare a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago; their dominance continued through the Jurassic and Cretaceous periods. Reverse genetic engineering and the fossil record both demonstrate that birds are modern feathered dinosaurs, having evolved from earlier theropods during the late Jurassic Period. As such, birds were the only dinosaur lineage to survive the Cretaceous–Paleogene extinction event 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds. — Wikipedia

    on June 3, 2020 at 2:45 pm

    More than 110 million years ago, a lumbering 1,300-kilogram, armor-plated dinosaur ate its last meal, died, and was washed out to sea in what is now northern Alberta. This ancient beast then sank onto its thorny back, churning up mud in the seabed that entombed it -- until its fossilized body was discovered in a mine near Fort McMurray in 2011.

    Palaeontologists from St Petersburg University have been the first to study in detail the structure of the brain and blood vessels in the skull of the ankylosaur Bissektipelta archibaldi, an herbivorous dinosaur somewhat similar in appearance to a modern armadillo. Scientists produced the first three-dimensional computer reconstruction of a dinosaur endocast made in Russia,a digital cast of its braincase. It made it possible to determine that ankylosaurs, and Bissektipelta in particular, were […]

    on June 3, 2020 at 1:58 pm

    Scientists from the SETI Institute and Purdue University have found that the only way to produce Deimos's unusually tilted orbit is for Mars to have had a ring billions of years ago. While some of the more massive planets in our solar system have giant rings and numerous big moons, Mars only has two small, misshapen moons, Phobos and Deimos. Although these moons are small, their peculiar orbits hide important secrets about their past.
