Fossil Discoveries
The fossils attributed to "Angustungui" were discovered in 2016 by Li Daqing in the Qigu Formation at Qiketai, Shanshan County. The holotype specimen, SS V16001, comprises elements of the axial skeleton, pectoral girdle, pelvic girdle, limbs, and armor. A paratype specimen, SS V16002, consists of a right coracoid and a right scapula.
Taxonomic Context
In the bioRxiv pre-print where the name was announced, phylogenetic analysis recovered "Angustungui" as a sister taxon to "Loricatosaurus," indicating a close evolutionary relationship between the two genera. As an informally named genus, "Angustungui" has not yet undergone formal scientific description and validation according to the standards of the International Commission on Zoological Nomenclature.

Related Dinosaur species
Chienkosaurus
Chienkosaurus is a dubious genus of carnivorous theropod dinosaur from the Late Jurassic of China. Its name means "lizard of Jiange County," and it was likely related to Szechuanosaurus. The genus is known from very limited fossil material, primarily teeth, leading to its classification as dubious.
Abrosaurus
Abrosaurus was a genus of macronarian sauropod dinosaur that lived during the Middle Jurassic Period in what is now Asia. It is known for its relatively small size for a sauropod and its distinctive boxy skull with a prominent nasal arch. The only named species, Abrosaurus dongpoi, was discovered in China.
Charonosaurus
Charonosaurus was a large lambeosaurine hadrosaurid dinosaur that inhabited northeastern China during the Late Cretaceous period. Similar in appearance to Parasaurolophus, it is distinguished by its size and the geological context of its discovery. Fossils suggest it lived in herds and was a prey animal for larger carnivores.
