Previously, it had been described as a species of Yandusaurus, Y. multidens (He and Cai, 1983), but was reclassified as a new taxon by Paul M. Barrett, Richard J. Butler and Fabien Knoll in 2005, who diagnosed this anatomically conservative species as follows: "A small ornithischian dinosaur distinguished from all other basal ornithischians by ...
There is no official, canonical list of pterosaur genera, but the most thorough attempts can be found at the Pterosauria section of Mikko Haaramo's Phylogeny Archive, [1] the Genus Index at Mike Hanson's The Pterosauria, [2] supplemented by the Pterosaur Species List, [3] and in the fourth supplement of Donald F. Glut's Dinosaurs: The Encyclopedia series.

Yuxisaurus was a basal thyreophoran. Depending on the dataset, it may be the sister taxon to the German Emausaurus or more basal than Scelidosaurus and eurypods.The discovery of Yuxisaurus definitively proves that thyreophorans were present in Asia during the Early Jurassic, as other potential records of Early Jurassic Asian thyreophorans, Bienosaurus and Tatisaurus, are too fragmentary to be ...
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
