Bistahieversor Mount
''Bistahieversor'' (meaning "Bistahi destroyer"), also known as the "Bisti Beast", is a genus of eutyrannosaurian tyrannosauroid dinosaur; the genus contains only a single known species, ''B. sealeyi'', described in 2010, from the Late Cretaceous of New Mexico. The holotype and a juvenile were found in the Hunter Wash Member of the Kirtland Formation, while other specimens came from the underlying Fossil Forest member of the Fruitland Formation. This dates ''Bistahieversor'' approximately 75.5 to 74.5 million years ago, found in sediments spanning a million years. Discovery and naming The first remains now attributed to ''Bistahieversor'', a partial skull and skeleton, were described in 1990 as a specimen of ''Aublysodon''. Additional remains, consisting of the incomplete skull and skeleton of a juvenile, were described in 1992. Another, complete, skull and partial skeleton were found in the Bisti/De-Na-Zin Wilderness of New Mexico in 1998, known colloquially as the "Bisti Beas ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ...

Zhuchengtyrannus
''Zhuchengtyrannus'' (meaning "Zhucheng tyrant") is a genus of tyrannosaurid theropod dinosaur known from the Campanian stage of the Late Cretaceous of Shandong Province, China. It belongs to the subfamily Tyrannosaurinae, and contains a single species, ''Zhuchengtyrannus magnus''. Discovery and naming ''Zhuchengtyrannus'' was first described and named by David W. E. Hone, Kebai Wang, Corwin Sullivan, Xijin Zhao, Shuqing Chen, Dunjin Li, Shuan Ji, Qiang Ji and Xing Xu in 2011 and the type species is ''Zhuchengtyrannus magnus''. The generic name is derived from the word ''Zhucheng'', which refers to the type locality, and ''tyrant'' in reference to its phylogenetic position as a tyrannosaurid. The specific name ''magnus'' meaning "great" in Latin refers to the relatively large size of ''Zhuchengtyrannus''. ''Zhuchengtyrannus'' is known solely from the holotype ZCDM V0031, a nearly complete right maxilla and associated left dentary (lower jaw, both with teeth) discovered around 2 ...

Tarbosaurus
''Tarbosaurus'' ( ; meaning "alarming lizard") is a genus of tyrannosaurid dinosaur that flourished in Asia about 70 million years ago, at the end of the Late Cretaceous Period, considered to contain a single known species, ''Tarbosaurus bataar''. Fossils have been recovered from the Nemegt Formation of Mongolia, with more fragmentary remains found further afield in the Subashi Formation of China. Although many species have been named, modern paleontologists recognize only one, ''T. bataar'', as valid. Some experts see this species as an Asian representative of the North American genus ''Tyrannosaurus''; this would make the genus ''Tarbosaurus'' redundant. ''Tarbosaurus'' and ''Tyrannosaurus'', if not synonymous, are considered to be at least closely related genera. ''Alioramus'', also from Mongolia, has previously been thought by some authorities to be the closest relative of ''Tarbosaurus'', though this has since been disproven with the discovery of '' Qianzhousaurus'' and ...

Nanuqsaurus
''Nanuqsaurus'' (meaning "polar bear lizard") is a genus of carnivorous tyrannosaurid theropod known from the Late Cretaceous period (early Late Maastrichtian stage) Prince Creek Formation of the North Slope of Alaska, United States. It contains a single species, ''Nanuqsaurus hoglundi'', known only from a partial skull and multiple undescribed postcranial and teeth elements. Discovery and naming In 2006, at the Kikak-Tegoseak Quarry, in North Slope Borough in the north of Alaska, fossils were found of a medium-sized theropod, with an estimated skull length of . These were first referred to ''Gorgosaurus'' and later to ''Albertosaurus''. After preparation in the Perot Museum of Nature and Science (Dallas Museum of Natural History) it was recognized these represented a species new to science. The holotype, DMNH 21461, has been found in a layer of the Prince Creek Formation, dated at 69.1 million years. It consists of a partial skull with a lower jaw, which were found very close to ...

Lythronax
''Lythronax'' () is a genus of tyrannosaurid dinosaur that lived in North America around 81.9-81.5 million years ago during the Late Cretaceous period. The only known specimen was discovered in Utah in the Wahweap Formation of the Grand Staircase–Escalante National Monument in 2009, and it consists of a partial skull and skeleton. In 2013, it became the basis of the new genus and species ''Lythronax argestes''; the generic name ''Lythronax'' means "gore king", and the specific name ''argestes'' originates from the Greek poet Homer's name for the wind from the southwest, in reference to the specimen's geographic provenance in North America. Size estimates for ''Lythronax'' have ranged between in length, and between in weight. It was a heavily built tyrannosaurid, and as a member of that group, it would have had small, two-fingered forelimbs, strong hindlimbs, and a very robust skull. The rear part of the skull of ''Lythronax'' appears to have been very broad, with eye socket ...

Teratophoneus
''Teratophoneus'' ("monstrous murderer"; Greek: ''teras'', "monster" and ''phoneus'', "murderer") is a genus of tyrannosaurid dinosaur which lived during the late Cretaceous period (late Campanian age, about 77 to 76 million years ago) in what is now Utah, United States, containing a single known species, ''T. curriei''. It is known from an incomplete skull and postcranial skeleton recovered from the Kaiparowits Formation. It was specifically named ''T. curriei'' in honor of Philip J. Currie. Discovery and naming Fossils of ''Teratophoneus'' were first found in the Kaiparowits Formation of southern Utah. Later, fossils from the same formation were discovered and identified as the genus. Argon-argon radiometric dating indicates that the Kaiparowits Formation was deposited between 76.1 and 74.0 million years ago, during the Campanian stage of the Late Cretaceous period. This date means that ''Teratophoneus'' lived in the middle of the Campanian stage of the Late Cretaceous. ...

Tyrannosaurinae
The tyrannosaurines (Tyrannosaurinae) is an extinct subfamily of Tyrannosauridae a family of coelurosaurian theropod dinosaurs that consists of at least three tribes and several genera. All fossils of these genera have been found in the Late Cretaceous deposits of western North America and east Asia. Compare to the related subfamily Albertosaurinae, tyrannosaurines overall are more robust and larger though the alioramins were gracile by comparison. This subfamily also includes the oldest known tyrannosaurid genus ''Lythronax'' as well as the youngest and most famous member of the group, ''Tyrannosaurus rex''. History of discovery The first remains of tyrannosaurids were uncovered during expeditions led by the Geological Survey of Canada, which located numerous scattered teeth. These distinctive dinosaur teeth were given the name ''Deinodon'' ("terrible tooth") by Joseph Leidy in 1856. In 1892 Edward Drinker Cope described more tyrannosaur material in the form of isolated vertebra ...
