(Ulugh Beg's lizard).
Named By: Kohei Tanaka, Otabek Ulugbek Ogli Anvarov, Darla K. Zelenitsky, Akhmadjon Shayakubovich Ahmedshaev, & Yoshitsugu Kobayashi - 2021.
Classification: Chordata, Dinosauria, Saurischia, Theropoda, Carcharodontosauria.
Species: U. uzbekistanensis (type).
Size: Uncertain due to lack of fossil remains. Comparison of holotype fossil to other carcharodontosaurid genera suggests a skull size of about 90 centimetres. Body length of holotype individual about 7.5 to 8 meters.
Known locations: Uzbekistan - Bissekty Formation.
Time period: Turonian of the Cretaceous.
Fossil representation: Holotype a partial left maxilla. Further skull bones and teeth referred to the genus.
is a genus of carcharodontosaurid
theropod dinosaur that lived in
Central Asia during the early stages of the Late Cretaceous,
specifically the Turonian period. The carcharodontosaurid theropod
dinosaurs were apex predators that rose to prominence during the early
Cretaceous, however there is plenty of fossil evidence to show that
as a group they continued to be key predators well into the early
stages of the late cretaceous, especially in South America, but
also now it seems central Asia as well.
Ulughbegsaurus was named from a partial maxilla, the tooth bearing bone of the upper jaw. Like other carcharodontosaurid dinosaurs, Ulughbegsaurus would have had blade like teeth specifically adapted for slicing flesh as opposed to crunching through bone. There are several other kinds of dinosaurs known from the same fossil formation as Ulughbegsaurus, though sauropod and large ornithopod/hadrosauroid dinosaurs may have been the easiest prey.
Ulughbegsaurus is named after Mīrzā Muhammad Tāraghay bin Shāhrukh who is more popularly known around the world as Ulugh Beg, who was once a Sultan of the Timurid Empire, noted for his work in mathematics and astronomy. The type species name of Ulughbegsaurus, ‘uzbekistanensis’, simply means ‘from Uzbekistan’.
