Stegosaurus 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 strata, dating to between 155 and 145 million years ago. Of the species that have been classified in the upper Morrison Formation of the western US, only three are universally recognized: S. stenops, S. ungulatus and S. sulcatus. The remains of over 80 individual animals of this genus have been found. Stegosaurus would have lived alongside dinosaurs such as Apatosaurus, Diplodocus, Camarasaurus and Allosaurus, the latter of which may have preyed on it.
Timeline of paleontology
Sauropoda, whose members are known as sauropods, is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads, and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include Apatosaurus, Brachiosaurus, Brontosaurus, Camarasaurus, and Diplodocus.
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." In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia, based on their hip structure. These divisions have proved remarkably enduring, even through several seismic changes in the taxonomy of dinosaurs.
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae. They were found in Asia, Africa, North America, South America, and Europe from the Miocene to the Pleistocene, living from about 16 million until about 10,000 years ago.
Dryosaurus is a genus of an ornithopod dinosaur that lived in the Late Jurassic period. It was an iguanodont. Fossils have been found in the western United States and were first discovered in the late 19th century. Valdosaurus canaliculatus and Dysalotosaurus lettowvorbecki were both formerly considered to represent species of Dryosaurus.
Age of Reptiles is a series of comics written by Ricardo Delgado published by Dark Horse Comics.
The Lost World is a 1925 American silent fantasy giant monster adventure film directed by Harry O. Hoyt and written by Marion Fairfax, adapted from Arthur Conan Doyle's 1912 novel of the same name.
The Land That Time Forgot is a 1974 British-American adventure fantasy film directed by Kevin Connor and written by Michael Moorcock and James Cawthorn, based upon the 1918 novel The Land That Time Forgot by Edgar Rice Burroughs. It stars Doug McClure, John McEnery, Keith Barron, Susan Penhaligon, Anthony Ainley and Declan Mulholland.
Saurophaganax is a genus of large allosaurid dinosaur from the Morrison Formation of Late Jurassic Oklahoma, United States. Some paleontologists consider it to be a junior synonym and species of Allosaurus. Saurophaganax represents a very large Morrison allosaurid characterized by horizontal laminae at the bases of the dorsal neural spines above the transverse processes, and "meat-chopper" chevrons. It was the largest terrestrial carnivore of North America during the Late Jurassic, reaching 10.5 metres (34 ft) in length and 2.7–3.8 metric tons in body mass.
Marshosaurus is a genus of medium-sized carnivorous theropod dinosaur, belonging to the Megalosauroidea, from the Late Jurassic Morrison Formation of Utah and possibly Colorado.
The Carnegie Collection was a series of authentic replicas based on dinosaurs and other extinct prehistoric creatures, using fossils featured at the Carnegie Museum of Natural History as references. They were produced by Florida-based company Safari Ltd., known for their hand-painted replicas, from 1988 to 2015, and became known as "the world’s premier line of scale model dinosaur figures."
Diplodocus was a genus of diplodocid sauropod dinosaurs, whose fossils were first discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a Neo-Latin term derived from Greek διπλός (diplos) "double" and δοκός (dokos) "beam", in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique.
Dinosaur Ridge is a segment of the Dakota Hogback in the Morrison Fossil Area National Natural Landmark located in Jefferson County, Colorado, near the town of Morrison and just west of Denver.
Dinosaur Train is a animated television series aimed at preschoolers ages 3 to 6 and created by Craig Bartlett, who also created Nickelodeon's Hey Arnold!. The series features a Tyrannosaurus rex named Buddy who, together with the rest of his family, who are all Pteranodons, takes the Dinosaur Train to explore his time period, and have adventures with a variety of dinosaurs. It is co-produced by The Jim Henson Company in association with the Infocomm Media Development Authority, Sparky Animation, FableVision, Snee-Oosh, Inc., Reel FX, and Sea to Sky Entertainment. As of September 2018, PBS Kids had ordered 11 more episodes, taking the total number of episodes to 100. A film based on the series from Universal Pictures and Universal 1440 Entertainment titled, Dinosaur Train: Adventure Island premiered on April 12, 2021.
Paleontology in Colorado refers to paleontological research occurring within or conducted by people from the U.S. state of Colorado. The geologic column of Colorado spans about one third of Earth's history. Fossils can be found almost everywhere in the state but are not evenly distributed among all the ages of the state's rocks. During the early Paleozoic, Colorado was covered by a warm shallow sea that would come to be home to creatures like brachiopods, conodonts, ostracoderms, sharks and trilobites. This sea withdrew from the state between the Silurian and early Devonian leaving a gap in the local rock record. It returned during the Carboniferous. Areas of the state not submerged were richly vegetated and inhabited by amphibians that left behind footprints that would later fossilize. During the Permian, the sea withdrew and alluvial fans and sand dunes spread across the state. Many trace fossils are known from these deposits.
Jurassic Park, later also referred to as Jurassic World, is an American science fiction adventure media franchise. It focuses on the cloning of dinosaurs through ancient DNA, extracted from mosquitoes that have been fossilized in amber. The franchise explores the ethics of cloning and genetic engineering, and the morals behind de-extinction.
Sri Lanka exhibits a remarkable biological diversity and is considered to be the richest country in Asia in terms of species concentration.
