Although Eomamenchisaurus arrived with all the faff and fanfare customarily afforded to brand new dinosaur species, it may actually be a specimen of the already-described Yuanmousaurus which hails from the same neighbourhood.
(Dawn Mamenchisaurus from Yuanmou)EtymologyEomamenchisaurus is derived from the Greek "eo" (dawn) and "Mamenchisaurus", named for a dinosaur that it's supposedly closely related to but older than; Mamenchisaurus.
The species epithet, yuanmouensis, is derived from "Yuanmou" (its place of discovery) and the Latin "ensis" (from).
DiscoveryThe remains of Eomamenchisaurus were discovered in the Zhanghe Formation at Banqing Houshanliangzi, Yuanmou (also known as Jiangyi) County, Yunnan Province, China.
The holotype (CXMVZA 165) is a partial skeleton, including eight back vertebrae， a partial hip，a shinbone and both thighs.
