Dinheirosaurus lourinhanensis

After paleontologists had removed some dinosaur fossils from Porto Dinheiro Cliff between 1987-1992, they lumped them with Lourinhasaurus alenquerensis, a fellow Portuguese sauropod that spent many-a-year erroneously assigned to Apatosaurus. But Bonaparte and Mateus named these remnants Dinheirosaurus a year later, having realised that it and Lourinhasaurus lacked comparable bones. Further discoveries could either cement the pair as separate taxa or prove their synonymy, but new remains were not needed; Mannion confirmed they were distinct in 2011 after studying Dinheirosaurus elements that were previously undescribed.
Etymology
Dinheirosaurus is derived from "Dinheiro" (from Porto Dinheiro where the holotype was discovered) and the Greek "sauros" (lizard).
The species epithet, lourinhanensis, is derived from "Lourinha" (for the nearby town of Lourinhã) and the Latin "ensis" (from).
Discovery
The remains of Dinheirosaurus were discovered in the Amoreira-Porto Novo Member of the Lourinhã Formation at Praia de Porto Dinheiro cliff, near Lourinhã, Estremadura, west-central Portugal, by Mr. Carlos Anunciação in 1983.
The holotype (ML 414, housed at Museu da Lourinhã) consists of two neck (cervical) vertebrae, nine back (dorsal) vertebrae, some ribs, a partial hip bone (pubis), gastroliths and other odds and sods.
