(The Arrieros' Laguna Brava Lizard)Etymology
Bravasaurus is derived from "Brava" (for Laguna Brava; a lake for which the Laguna Brava Provincial Park is named) and the Greek "sauros" (lizard).
The
species epithet,
arrierosorum,
honours the Arrieros (colloquially known as "muleteers" or "muleskinners"): A person or people who transport goods using pack animals, in this case, the folk who wrangled cattle across the Andes in the 19th century.

Discovery
The remains of
Bravasaurus were discovered in sandstone levels 34 meters above the base of the Ciénaga del Río Huaco Formation at QSD (Quebrada de Santo Domingo) in the Andes of La Rioja, NW Argentina. The Quebrada de Santo Domingo locality is famous for its copious fossilised sauropod eggs, making it one of the largest nesting sites documented worldwide.
The
holotype (CRILAR-Pv 612) is two skull bones, four neck, five back, and three tail vertebrae, a few ribs, three chevrons, a left upper arm, a fragmentary lower arm, a hand bone (metacarpal IV), a partial pelvic girdle, a left thigh, and both calf bones.
The paratype (CRILAR-Pv 613) is an isolated tooth, a hip bone (right ilium), a right thigh, and ribs.
