Liushusaurus acanthocaudata (Evans and Wang 2010) Early Cretaceous, ~10 cm in length, was described from eight specimens and was originally and correctly nested at the base of the Scleroglossa. Derived from a sister to Calanguban, Liushusaurus nests at the base of the Iguania, includng Euposaurus and Iguana.
Overall larger and distinct from Calanguban, the skull of Liushusaurus was lower with a smaller orbit. The naris is elongte and angled lower than 30 degrees. No quadratojugal process appears on the jugal. The squamosals is a slender strip. The torso was relatively longer. The tail remained short.
The scapulocoracoid was larger and fenestrated. The hand and foot were similar in size, thus the hand was larger and more robust, and the foot was much smaller with shorter toes.
