Oceanotitan dantasi

(Dantas' Ocean Giant)Etymology
Oceanotitan is derived from the Latin "oceanus" (ocean), referring to its discovery in a locality overlooking the Atlantic Ocean, and the Greek "titan" (a giant pre-Olympian deity in Greek mythology). The name is also an homage to the song "Oceania", by Icelandic singer Björk from her 2004 album Medúlla. The species epithet, dantasi (DAN-tah-see), honours Portuguese paleontologist Pedro Dantas, whose work across the Lourinhã, Torres Vedras, and Pombal regions helped drive the late-20th-century renaissance of Portuguese dinosaur paleontology. He also oversaw the extraction of several key specimens, including the Dinheirosaurus lourinhanensis holotype.

Discovery
The remains of Oceanotitan were discovered in the Praia da Amoreira-Porto Novo Member of the Lourinha Formation, at the foot of the coastal cliffs of Praia de Valmitão, Lourinhã, Lisbon, Portugal, by a private collector, who donated them to the Sociedade de História Natural (SHN) at Torres Vedras in 2008.
The holotype (SHN 181) includes eight tail vertebrae plus seventeen tailbone fragments, one complete chevron and part of another, the right shoulder girdle, an almost complete pelvic girdle, and the right thigh, shin, calf, and ankle, from a single individual.
