Aoniraptor

Aoniraptor is a megaraptoran theropod from the Late Cretaceous of Argentina. It was recovered by Matias Motta from the Violante Farm, part of the Huincul Formation. It was discovered in 2010, but only formally described in 2016.[1] Aoniraptor has been considered as synonymous with the theropod Gualicho, described from the same formation, due to the similarities of their caudal vertebrae.[2][3]

Aranciaga Rolando et al. in 2020 performed a comparative analysis between Aoniraptor and Gualicho, and found many differences between the two.[4]

Etymology

Aoniraptor comes from the Tehuelche language word "Aoni", which means south, and the Latin word "raptor", meaning thief. The specific name, libertatem, comes from the Latin word for freedom, as it was discovered on the bicentennial of Argentina's independence from Spain in 1810.
