(Magnificent Southern Earth Shaker)EtymologyAustroposeidon is derived from the Latin "austral" (southern) and "Poseidon" (the Greek God who, in his guise as Enisokhthon ("earth shaker"), was responsible for earthquakes.
The species epithet, magnificus, means magnificent, great, elevated, or noble in Latin, in allusion to the large size of the specimen.
DiscoveryThe remains of Austroposeidon were discovered in the Presidente Prudente Formation (Bauru Group) at Raposo Tavares road (BR-374) on the outskirts of Presidente Prudente City, southwestern São Paulo State, Brasil, by Llewellyn Ivor Price in 1953. The authors tried, and failed, to relocate the exact quarry, because the area is urbanised nowadays.
The holotype (MCT 1628-R) is composed of two incomplete neck vertebrae, one neck rib, one back vertebra, seven fragments of back vertebrae and a fragment of hip vertebra.
