Evolution of the wolf. Illustration of a Pleistocene wolf cranium that was found in Kents Cavern, Torquay, England [1] It is widely agreed that the evolutionary lineage of the grey wolf can be traced back 2 million years to the Early Pleistocene species Canis etruscus, and its successor the Middle Pleistocene Canis mosbachensis. [2] [3] The ...
Stegosaurus ( / ˌstɛɡəˈsɔːrəs /; [2] lit. 'roof-lizard') is a genus of herbivorous, four-legged, armored dinosaur from the Late Jurassic, characterized by the distinctive kite-shaped upright plates along their backs and spikes on their tails. Fossils of the genus have been found in the western United States and in Portugal, where they are found in Kimmeridgian - to Tithonian -aged ...
Dinosaurs Alive! is a 2007 IMAX documentary produced by Giant Screen Films about various dinosaurs that inhabited the Earth between 251 and 65 Ma. The documentary features animals from the Triassic period of New Mexico to the Cretaceous period of Mongolia, as well as the American Museum of Natural History's research on both periods.
The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have been subject to much research and debate.
Coelophysis was a bipedal, carnivorous, theropod dinosaur and a fast, agile runner. [41] Despite its basal position within Theropoda, the bauplan of Coelophysis differed from those of other basal theropods, such as Herrerasaurus, showing more derived traits common in theropods that superseded it.
Ornithischia ( / ˌɔːrnəˈθɪski.ə /) is an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. [6] The name Ornithischia, or "bird-hipped", reflects this similarity and is derived from the Greek stem ornith- ( ὀρνιθ- ), meaning "bird", and ischion ( ἴσχιον ...
Spinosauridae (or spinosaurids) is a clade or family of tetanuran theropod dinosaurs comprising ten to seventeen known genera. Spinosaurid fossils have been recovered worldwide, including Africa, Europe, South America and Asia. Their remains have generally been attributed to the Early to Mid Cretaceous . Spinosaurids were large bipedal carnivores.
Suchomimus (meaning "crocodile mimic") is a genus of spinosaur dinosaur that lived between 125 and 112 million years ago in what is now Niger, north Africa, during the Aptian to early Albian stages of the Early Cretaceous period. It was named and described by paleontologist Paul Sereno and colleagues in 1998, based on a partial skeleton from the Elrhaz Formation. Suchomimus 's long and shallow ...
