''Guanlingsaurus'' is an extinct genus of shastasaurid ichthyosaur from the Late Triassic of China. It grew up to in length and has a wide, triangular skull with a short and toothless snout. Discovery It is known from a single species, ''Guanlingsaurus liangae'', that was found in the Carnian-age Falang Formation of Guanling County, which is in the province of Guizhou. The genus and species were first named in 2000 on the basis of an incomplete adult skeleton. More complete skeletons were described in 2011, and a complete skeleton belonging to a juvenile was described in 2013. In 2011 ''Guanlingsaurus liangae'' was reassigned to the genus '' Shastasaurus'', which includes two species from North America that are known from more complete fossils than ''Guanlingsaurus''. However, the description of the juvenile specimen in 2013 revealed several features that make ''G. liangae'' distinct from ''Shastasaurus'' species, and the name was reinstated.

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...
