Discovery and naming
The holotype, PVL 3670-11, was found at Arroyo-Morterito in the Los Blanquitos Formation, dating to the Campanian. It consists of a left pubis, 514 millimetres (1.686 ft) long. The specimen was re-studied by Fernando Novas and Federico Agnolin in 2004, who concluded that the orientation of the pubis had been misinterpreted: it pointed backwards, as was shown by the fossil still being attached to a displaced part of the pubic peduncle of the ilium.[2]

Description
Based on the fragmentary fossil remains, it is estimated that Unquillosaurus may have had a total body length of about 2–3 metres (6.6–9.8 ft).[1]

Unquillosaurus is known from the Los Blanquitos Formation. The abelisaurid theropod Guemesia is also known from this formation,[7] as well as fossils of what may belong to a species of Titanosaurus.[8]
