Lavocatisaurus

Lavocatisaurus (meaning "René Lavocat's lizard") is a genus of sauropod in the family Rebbachisauridae from the Early Cretaceous (Aptian to Albian) Rayoso Formation of the Neuquén Basin, northern Patagonia, Argentina.

== Discovery and naming == In 2009, a group of Spanish–Argentinean palaeontologists attempted to locate the site from which the holotype of the rebbachisaurid Rayososaurus agrioensis was discovered. While investigating strata belonging to the Pichi Neuquén Member of the Rayoso Formation, the remains of a different rebbachisaurid taxon, consisting of two juveniles and an adult, were uncovered. The specimens were excavated over the next two years, and once completed, the material was divided between the Museo Provincial de Ciencias Naturales and the Museo Paleontológico Egidio Feruglio for preparation. In 2018, the new taxon, Lavocatisaurus agrioensis, was described, with the adult (MOZ-Pv1232) designated as the holotype. The generic name refers to the French palaeontologist René Lavocat, while the specific name refers to Agrio del Medio, the locality from which the specimens were recovered.
