While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...
A model of the hypothetical dinosauroid, Dinosaur Museum, Dorchester The dinosauroid is a hypothetical species created by Dale A. Russell in 1982. Russell theorized that if a dinosaur such as Stenonychosaurus had not perished in the Cretaceous–Paleogene extinction event, its descendants might have evolved to fill the same ecological niche as humans.

Ceratopsia or Ceratopia (/ ˌ s ɛr ə ˈ t ɒ p s i ə / or / ˌ s ɛr ə ˈ t oʊ p i ə /; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period, although ancestral forms lived earlier, in the Late Jurassic of Asia.
Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria." [1] In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia, based on their hip structure. [2]
With the recent description of Maip, I thought it would be appropriate to make size comparison diagrams for the named dinosaurs of the Chorrillo Formation.All three pages (Isasicursor, Nullotitan, and Maip) are low on images, so perhaps a new version of the skeletal diagrams could be made without the human scale for use on the page.
Designasaurus is an educational game created by Ezra Sidran and published by Britannica Software. It was released for Amiga, Apple II, Apple IIGS, Commodore 64, and MS-DOS. [2] [3] [4] The game is about creating a custom dinosaur and helping it survive. It is divided into three activities: "Walk-a-Dinosaur", "Build-a-Dinosaur" and "Print-a ...
Dinosaurs should be shown with fleshy pads underneath their feet and toes, and on their hands and fingers, these should match the pattern seen on tracks known to belong to related animals. [3] No dinosaurs could cross the radius and ulna arm bones, making their ability to rotate their hands very limited/impossible.
