The game consists of three parts which is the game itself, creating a dinosaur, and printing coloring pages of dinosaurs. [7] To create a dinosaur, a paleontologist of the Museum of Natural History allows the player to use bones from its collection to build their own dinosaur. Every design details the likelihood of the final dinosaur surviving. [8]
The braincase is mostly hidden from view by overlying bones; only the occipital region (rear part) is exposed. The uppermost bone of the occipital region is the supraoccipital, which in Bajadasaurus was completely fused to the exoccipital-opisthotic bone below and featured a distinct and narrow longitudinal ridge, the sagittal nuchal crest.
Einiosaurus parietal frill bones, including of holotype specimen (A, MOR 456 8-9-6-1). At the time of the expeditions, it was assumed that all horned dinosaur fossils found in the reservation belonged to a single species, especially as they came from a limited geological time period, its duration estimated at about half a million years.

Deinocheirus (/ ˌ d aɪ n oʊ ˈ k aɪ r ə s / DY-no-KY-rəs) is a genus of large ornithomimosaur that lived during the Late Cretaceous around 70 million years ago. In 1965, a pair of large arms, shoulder girdles, and a few other bones of a new dinosaur were first discovered in the Nemegt Formation of Mongolia.
The discovery of gigantic bone beds of Centrosaurus in Canada suggest that they were gregarious animals and could have traveled in large herds. [2] A bone bed composed of Centrosaurus and Styracosaurus remains is known from the Dinosaur Park Formation in what is now Alberta. [21]
The mandible consists of both endochondral bones, which ossified from the Meckelian cartilage, and dermal bones. [5] In dinosaurs, only the dentary bears teeth. [25]: 40 mandibular fenestra The external mandibular fenestra is an opening in the lower jaw between the dentary, surangular, and angular bones. It is characteristic for archosauriforms ...
Brachiosaurus (/ ˌ b r æ k i ə ˈ s ɔː r ə s /) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154 to 150 million years ago. [1] It was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River valley in western Colorado, United States.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are 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.
