Actiosaurus

Actiosaurus (meaning "coast lizard") is an extinct genus of reptile first described by Henri Sauvage in 1883 from Antully bonebed, Autun (Triassic of France). The type species is "A. gaudryi" (commonly misspelled "A. gaudrii" after Boulenger). Little is known of it, and it is considered a "nomen dubium". "Actiosaurus" was originally described as a dinosaur in 1883 and was reinterpreted as an ichthyosaur in 1908. "Actiosaurus" may instead represent the remains of a choristodere. Fischer "et al." (2014) considered "A. gaudryi" to be a "species inquirenda", and noted the similarity of its bones to the limb bones of choristoderes.
