Ligabuesaurus

Description

Ligabuesaurus is a genus of titanosaurid sauropod dinosaur from the Early Cretaceous which lived in what is now Argentina. The type species, Ligabuesaurus leanzai, was described by Jose Bonaparte, Gonzalez Riga, and Sebastián Apesteguía in 2006, based on a partial skeleton. The specific name, leanzai, is dedicated to the geologist Dr. Héctor A. Leanza, who discovered the skeleton in the Lohan Cura Formation.
