Jobu Formation (Japan)

The Jobu Formation is a Cretaceous geologic formation of Late Cenomanian age. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The oldest confirmed tyrannosaurid premaxillary tooth was recovered from the Jobu Formation. [1] The mammal Sorlestes is also known from the formation.

Torvosaurus is a genus of carnivorous megalosaurid theropod dinosaur that lived approximately 165 to 148 million years ago during the late Middle and Late Jurassic period in what is now Colorado, Portugal, Germany, and possibly England, Tanzania, and Uruguay. It contains two currently recognized species, Torvosaurus tanneri and Torvosaurus gurneyi, plus a third species from Germany that is currently unnamed.

<i>Chilantaisaurus</i> Theropod dinosaur genus from the Late Cretaceous period

Chilantaisaurus is a genus of large theropod dinosaur, possibly a neovenatorid or basal coelurosaur, from the late Cretaceous Ulansuhai Formation of China. The type species, C. tashuikouensis, was described by Hu in 1964. Chilantaisaurus was a large theropod, estimated as weighing between 2.5 metric tons and 4 metric tons. In 2010, Brusatte et al. estimated it to weigh 6,000 kilograms (13,000 lb), based on femur length measurements. It is estimated to be around 11 m (36 ft) to 13 m (43 ft) long.

Timeline of tyrannosaur research

This timeline of tyrannosaur research is a chronological listing of events in the history of paleontology focused on the tyrannosaurs, a group of predatory theropod dinosaurs that began as small, long-armed bird-like creatures with elaborate cranial ornamentation but achieved apex predator status during the Late Cretaceous as their arms shrank and body size expanded. Although formally trained scientists did not begin to study tyrannosaur fossils until the mid-19th century, these remains may have been discovered by Native Americans and interpreted through a mythological lens. The Montana Crow tradition about thunder birds with two claws on their feet may have been inspired by isolated tyrannosaurid forelimbs found locally. Other legends possibly inspired by tyrannosaur remains include Cheyenne stories about a mythical creature called the Ahke, and Delaware stories about smoking the bones of ancient monsters to have wishes granted.

<i>Basilemys</i> Extinct genus of turtles

Basilemys is a large, terrestrial trionychoid turtle that was from the Upper Cretaceous time period. In Greek, the "Basil (name)" means royal or kingly and the word "Emys" means turtle. Therefore, Basilemys means King Turtle. The stratigraphic subdivisions of the Upper Cretaceous include Cenomanian, Turonian, Coniacian, Santonian, Campanian, and Maastrichtian. Basilemys was mostly from the Campanian and Maastrichtian subdivisions of the Cretaceous time period and is considered to be the largest terrestrial turtle of its time. This extinct genus of land turtles belongs to the family Nanhsiungchelyidae. Occurrences of Basilemys have largely been reported in the North America region. It is interesting to note that the family Nanhsiungchelyidae made its first appearance in the Lower Cretaceous in Asia and we know from Basilemys that this family appeared in the Upper Cretaceous in North America. The North American populations of Basilemys are considered to be immigrants from Asia through the Beringia during the Upper Cretaceous. In an analysis made by Sukhanov et al. on a new Nansiunghelyid turtle from the Upper Cretaceous of Mongolia, it was demonstrated that Asian nanhsiungchelyids gave rise to the North American nanhsiungchelyids. One genus from the family Nanhsiungchelyidae, Zangerlia, is similar to Basilemys in terms of skull proportions. However, Basilemys has a more complex triturating surface that includes well-defined pockets on the dentary. Basilemys also has tooth-like projections on the triturating surface of the maxilla.

Batylykh Formation

The Batylykh Formation is a geological formation in Yakutia, Russia. It is of an uncertain Early Cretaceous age, probably dating between the Berriasian and the Barremian. It is the oldest unit of the 1,500 metres (4,900 ft) thick Sangar Series within the Vilyuy syneclise. The mudstones, sandstones and shales of the formation were deposited in a fluvial to lacustrine environment.

The Bladen Formation is a geologic formation in North Carolina. It is known for a plethora of terrestrial and aquatic Cretaceous fossils, including dinosaurs and mosasaurs.

Ulaanoosh Formation

The Ulaanoosh Formation, formerly Baruunbayan Formation, is a geologic formation in the Ömnögovi Province of southern Mongolia. The formation dates to the Albian to Cenomanian stages of the Cretaceous. The Ulaanoosh Formation has provided fossils of dinosaurs, turtles and dinosaur eggs assigned to Parafaveoloolithus sp.. In 2020, the neoceratopsian Beg tse was described from the alluvial sandstones, mudstones and conglomerates of the formation.
