Tyrannosaurus is a genus of large theropod dinosaur. The type species Tyrannosaurus rex, often called T. rex or colloquially T-Rex, is one of the best represented theropods. It lived throughout what is now western North America, on what was then an island continent known as Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the Upper Cretaceous period, 72.7 to 66 million years ago. It was the last known member of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event.
Triceratops is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America. It was one of the last-known non-avian dinosaurs and lived until the Cretaceous–Paleogene extinction event 66 million years ago. The name Triceratops, which means 'three-horned face', is derived from the Greek words trí- meaning 'three', kéras meaning 'horn', and ṓps meaning 'face'.
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.
Ceratopsidae is a family of ceratopsian dinosaurs including Triceratops, Centrosaurus, and Styracosaurus. All known species were quadrupedal herbivores from the Upper Cretaceous. All but one species are known from western North America, which formed the island continent of Laramidia during most of the Late Cretaceous. Ceratopsids are characterized by beaks, rows of shearing teeth in the back of the jaw, elaborate nasal horns, and a thin parietal-squamosal shelf that extends back and up into a frill. The group is divided into two subfamilies—Chasmosaurinae and Centrosaurinae. The chasmosaurines are generally characterized by long, triangular frills and well-developed brow horns. The centrosaurines had well-developed nasal horns or nasal bosses, shorter and more rectangular frills, and elaborate spines on the back of the frill.
Edmontosaurus, often colloquially and historically known as Anatosaurus or Anatotitan, is a genus of hadrosaurid (duck-billed) dinosaur. It contains two known species: Edmontosaurus regalis and Edmontosaurus annectens. Fossils of E. regalis have been found in rocks of western North America that date from the late Campanian age of the Cretaceous period 73 million years ago, while those of E. annectens were found in the same geographic region from rocks dated to the end of the Maastrichtian age, 66 million years ago. Edmontosaurus was one of the last non-avian dinosaurs to ever exist, and lived alongside dinosaurs like Triceratops, Tyrannosaurus, Ankylosaurus, and Pachycephalosaurus shortly before the Cretaceous–Paleogene extinction event.
Emmet Sullivan, was an American sculptor. He was born in Powder River, Montana, and claimed to have worked on Mount Rushmore. He created the five dinosaurs in Dinosaur Park in Rapid City, South Dakota in 1934, his first large-scale project. His other dinosaur creations were the Apatosaurus at Wall Drug in Wall, South Dakota in the late 1960s, and the many dinosaurs of Dinosaur World in Beaver, Arkansas. In 1966 Sullivan sculpted the 20 meter tall Christ of the Ozarks statue in Eureka Springs, Arkansas.
The Truth About Killer Dinosaurs is a two-part BBC documentary film, directed by Bill Oddie, in which a group of men test out dinosaur weapons, using studies. The first episode determines the winner of a battle between Tyrannosaurus and Triceratops, and the second compares the strength of an Ankylosaurus and Velociraptor. The episodes were broadcast on BBC 1 in August and September 2005. In the U.S., The Truth About killer Dinosaurs was also known as Dinosaur Face-Off.
When Dinosaurs Roamed America is a two-hour American television program that first aired on the Discovery Channel on July 15, 2001. The show features the reign of the non-avian dinosaurs in America over the course of more than 160 million years, through five different segments, each with their own variety of flora and fauna.
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."
Stegosaurus is one of the most recognizable types among cultural depictions of dinosaurs. It has been depicted on film, in cartoons, comics, as children's toys, as sculpture, and even was declared the state dinosaur of Colorado in 1982. Stegosaurus is a subject for inclusion in dinosaur toy and scale model lines, such as the Carnegie Collection.
Tyrannosaurus is one of the most iconic dinosaurs and is known from numerous specimens, some of which have individually acquired notability due to their scientific significance and media coverage.
Dinamation International Corporation was a robotics effects company based in San Juan Capistrano, Santa Ana, and Tustin, California, United States.
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.

Dinosaur Island was an animatronic dinosaur themed attraction at Sea World on the Gold Coast, Australia. The attraction was manufactured by Canadian company Dinosaurs Unearthed and opened on 16 June 2012.
Paleontology in the United States refers to paleontological research occurring within or conducted by people from the United States. Paleontologists have found that at the start of the Paleozoic era, what is now "North" America was actually in the southern hemisphere. Marine life flourished in the country's many seas. Later the seas were largely replaced by swamps, home to amphibians and early reptiles. When the continents had assembled into Pangaea drier conditions prevailed. The evolutionary precursors to mammals dominated the country until a mass extinction event ended their reign.
The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex 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.
The Dueling Dinosaurs or Montana Dueling Dinosaurs is a fossil specimen originating from the Hell Creek Formation of Montana. It consists of the fossilized skeletons of an adolescent Tyrannosaurus rex and a Triceratops horridus entangled with one another, and entombed in sandstone. The "dueling" inference comes from the numerous injuries sustained by both dinosaurs, including a tooth from the Tyrannosaurus embedded within the Triceratops, although it is not known whether they were actually buried fighting one another. Despite the scientific importance of the specimen, it has remained relatively obscure due to a lengthy legal dispute over property rights to the specimen, which has since been resolved. The fossil is currently in the possession of the North Carolina Museum of Natural Sciences.
