Huinculsaurus (meaning "Huincul Formation lizard") is a genus of elaphrosaurine noasaurid dinosaur from the Huincul Formation in Neuquén Province, Argentina. The type and only species is Huinculsaurus montesi. It is the youngest known elaphrosaurine, dating to the mid-Cretaceous period. [1]

Discovery and naming

Huinculsaurus is only known from thre thoracic and two sacral vertebrae from an immature individual. It was discovered ten meters away from where the original Ilokelesia specimen was discovered[2] and the vertebrae were mechanically separated during preparation. The genus was eventually named in 2020.[1]

Classification

Huinculsaurus was placed in the Elaphrosaurinae in 2020.[1] It was most closely related to Elaphrosaurus and Limusaurus, both from the Late Jurassic.
