Tyrannosaurus is a genus of large theropod dinosaur. The 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, 68 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.
Tyrannosaurus rex is unique among dinosaurs in its place in modern culture; paleontologist Robert Bakker has called it "the most popular dinosaur among people of all ages, all cultures, and all nationalities". Paleontologists Mark Norell and Lowell Dingus have likewise called it "the most famous dinosaur of all times." Paleoartist Gregory S. Paul has called it "the theropod. [...] This is the public's favorite dinosaur [...] Even the formations it is found in have fantastic names like Hell Creek and Lance." Other paleontologists agree with that and note that whenever a museum erects a new skeleton or bring in an animatronic model, visitor numbers go up. "Jurassic Park and King Kong would not have been the same without it." In the public mind, T. rex sets the standard of what a dinosaur should be. Science writer Riley Black similarly states, "In all of prehistory, there is no animal that commands our attention quite like Tyrannosaurus rex, the tyrant lizard king. Since the time this dinosaur was officially named in 1905, the enormous carnivore has stood as the ultimate dinosaur."
Eastend is a town in south-west part of the Canadian province of Saskatchewan, situated approximately 55 kilometres (34 mi) north of the Montana border and 85 kilometres (53 mi) east of the Alberta border.
The Frenchman Formation is stratigraphic unit of Late Cretaceous age in the Western Canada Sedimentary Basin. It is present in southern Saskatchewan and the Cypress Hills of southeastern Alberta. The formation was defined by G.M. Furnival in 1942 from observations of outcrops along the Frenchman River, between Ravenscrag and Highway 37. It contains the youngest of dinosaur genera, much like the Hell Creek Formation in the United States.
Highway 13 is a highway in the Canadian province of Saskatchewan. It runs from the Alberta border until it transitions into Highway 2 at the Manitoba border near Antler. Highway 13 is about 676 km (420 mi.) long. Highway 13 passes through Shaunavon, Assiniboia, Weyburn, Redvers and Carlyle. It is also referred to as the Red Coat Trail, as much of its length follows the route of the original historic path. A majority of the route between Wauchope and Govenlock going through the Palliser's Triangle is also referred to as the Ghost Town Trail.
Sue is the nickname given to FMNH PR 2081, which is one of the largest, most extensive, and best preserved Tyrannosaurus rex specimens ever found, at over 90 percent recovered by bulk. FMNH PR 2081 was discovered on August 12, 1990, by American explorer and fossil collector Sue Hendrickson, and was named after her.
The Bearpaw Formation, also called the Bearpaw Shale, is a geologic formation of Late Cretaceous (Campanian) age. It outcrops in the U.S. state of Montana, as well as the Canadian provinces of Alberta and Saskatchewan, and was named for the Bear Paw Mountains in Montana. It includes a wide range of marine fossils, as well as the remains of a few dinosaurs. It is known for its fossil ammonites, some of which are mined in Alberta to produce the organic gemstone ammolite.
"Stan", also known by its inventory number BHI 3033, is a Tyrannosaurus rex fossil found in the Hell Creek Formation in South Dakota, just outside of Buffalo in 1987, and excavated in 1992. It is the fifth most complete T. rex fossil discovered to date, at more than 70% bulk. In October 2020, the fossil was sold for $31.8 million at auction, making it the most expensive dinosaur specimen and fossil ever sold. In March 2022 Abu Dhabi's Department of Culture and Tourism stated that they had acquired Stan and were planning on displaying the fossil at a new museum of natural history scheduled to open in 2025.
Tyrannosaurus rex 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.
Terminonatator is a genus of elasmosaurid plesiosaur from the Late Cretaceous of Saskatchewan, Canada. It is known from a skull and partial skeleton from a young adult, found in the Campanian-age Bearpaw Formation near Notukeu Creek in Ponteix. Terminonatator is currently one of the youngest plesiosaurs from the Western Interior Seaway.
Herschel is a special service area in the Canadian province of Saskatchewan. It is the seat of the Rural Municipality of Mountain View No. 318 and held village status prior to December 31, 2006. The population was 30 people in 2016. The community is located 37 km northwest of the town of Rosetown at the intersection of Highway 31 and Highway 656, along a now abandoned section of the Kerrobert-Rosetown Canadian Pacific Railway line. Herschel is the home of the Ancient Echoes Interpretive Centre. The Vancouver-based backpack manufacturer Herschel Supply Co., founded by Lyndon and Jamie Cormack in 2009, adopted the name of Herschel, the town where three generations of their family grew up.
Carmichael is a special service area within the Rural Municipality of Carmichael No. 109, Saskatchewan, Canada that held village status prior to 2019. The population was 58 at the 2016 Census. Carmichael lies 1 km (1 mi) south of Highway 1 commonly known as the Trans Canada Highway, approximately 158 km (98 mi) east of city of Medicine Hat, Alberta.
Terminonaris is a genus of extinct pholidosaurid crocodyliforms that lived during the Late Cretaceous epoch. The name means: “enlarged snout or nose” at the front of the skull. Terminonaris is an early crocodile, within a subgroup called Mesoeucrocodylia. Its remains have only been found in North America and Europe. Originally known under the generic name Teleorhinus, it was once believed to be a teleosaurid. Both prehistoric crocodiles such as Terminonaris, as well as modern crocodiles, belong to the same group called crocodyliformes, although modern crocodiles have specific features that indicate they are distant relatives of this species and members of the subgroup Eusuchia.
The Eastend Formation is a stratigraphical unit of Maastrichtian age in the Western Canadian Sedimentary Basin. It takes its name from the town of Eastend, Saskatchewan, and was first described in outcrop around the settlement by L.S. Russell in 1932. The type locality was later defined south-west of the town by W.O. Kupsch in 1956.
Suskityrannus is a genus of small tyrannosauroid theropod from the Late Cretaceous in southern Laramidia. It contains a single species, Suskityrannus hazelae, believed to have lived roughly 92 million years ago. The type specimen was found in the Turonian-age Moreno Hill Formation of the Zuni Basin in western New Mexico.
Trix is a Tyrannosaurus rex specimen excavated in 2013 in Montana, United States by a team of paleontologists from the Naturalis Biodiversity Center in Leiden, the Netherlands and Black Hills institute of Geological Research in South Dakota. This Tyrannosaurus, over thirty years old – the oldest known Tyrannosaurus specimen – lived about 67 million years ago. It is considered to be the third most complete Tyrannosaurus found, with between 75% and 80% of its bone volume recovered. The specimen was named Trix after the former Queen Beatrix of the Netherlands. It is one of only two Tyrannosaurus specimens on permanent exhibit in mainland Europe. The other one is a specimen named Tristan on exhibit at the Natural History Museum of Berlin.
Titus is an obsidian black skeleton of a Tyrannosaurus rex discovered in Montana's Hell Creek Formation in 2014 and excavated in 2018.
Scotty is the nickname for the Tyrannosaurus rex fossil, catalogued as RSM P2523.8, that was discovered in Saskatchewan, Canada in 1991. The fossilised remains were painstakingly removed, almost completely by hand, over two decades from the rock in which they were embedded. When the preparation was complete in 2011, a ~65% complete T. rex skeleton was revealed.
