Motta, et al
Río Negro, Argentina
(Independant Southern Hunter)Etymology
is derived from the Tehuelche word "Aoni" (south) and the Latin "raptor" (plunderer), referring to its discovery in South America.
The species epithet
(meaning independence or freedom, in Latin), refers to the 1810 declaration of independence of Argentina from
the Spanish government. Although described in 2016, the remains of Aoniraptor
were discovered in 2010, which marked the 200th anniversary of this epic event.
The remains of Aoniraptor
were discovered in the Huincul Formation at the Violante farm, southeast of the Ezequiel Ramos-Mexía lake, Río Negro province, Argentina, by Matías Motta in 2010.
