Arrudatitan maximus
(The Largest Arruda Giant)Etymology
Arrudatitan is derived from "Arruda" (for late Professor Antonio de Celso Arruda Campos, fossil collector and first curator of the MPMA in Monte Alto) and the Greek "titan" (for the giant pre-Olympian deities of Greek mythology).
The
species epithet,
maximus, means "the largest" in Latin.
Discovery
The remains of
Arrudatitan were discovered in the Adamantina Formation (Bauru Group) at "Santa Irene" farm, near the border of Monte Alto and Cândido Rodrigues counties, São Paulo State, Brazil, by Ademir Frare and his 12-year-old nephew Luiz Augusto dos Santos Frare in 1997.
The
holotype (MPMA 12–0001-97) is two partial neck
vertebrae and seven partial neck ribs, three fragmentary back vertebra and twelve partial back ribs, eight tail vertebrae and eight chevrons, a probable fragmentary shoulder blade, an partial right upper arm, a left upper arm, a probably partial radius of the lower arm, a partial right thigh, a left thigh, a left ischium of the hip, and several unidentified fragments, that were named
Aeolosaurus maximus by Santucci and De Arruda-Campos in 2011.
Referred material includes a tail vertebra (CPP 248, that was erroneously published as CPP 298 by Santucci and Bertini in 2001) and an osteoderm (CPP 297), from the Peirópolis locality, Uberaba county, Minas Gerais State, Brazil.
