Patagotitan mayorum

(Mayo's Patagonian giant)Etymology
Patagotitan is derived from "Patagonia" (for the southern portion of South America) and "titan" (for the giant, primordial deities from Greek mythology). The species epithet, mayorum, honors the Mayo family on whose ranch the discovery was made.
Patagotitan represents not only one of the three largest known sauropods that are very close in size but also one of the most complete titanosaurs recovered to date, and was a precious find indeed. So it's a shame that ranch worker Aurelio Hernandez—who went looking for a lost sheep and found this critter's first colossal fossil (a lump of thigh) instead, but sadly passed before its official description—wasn't honored in some way, because Aurelio means "gold" in Spanish.
Discovery
The remains of Patagotitan were discovered in the Cerro Barcino Formation at "La Flecha" Ranch, Chubut Province, Patagonia, Argentina, by the late Aurelio Hernandez in 2012.
The holotype (MPEF-PV 3400) is the best preserved of at least six individuals from the same quarry, and includes three neck vertebrae, seven back vertebrae, six tail vertebrae, three chevrons, ribs, both sternal plates, the right shoulder girdle, both pubes (hip bones) and both thighs. The paratypes include much of the skeleton that is missing from the holotype but, one tooth aside, no skull material is known.
