Eomamenchisaurus yuanmouensis
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)Etymology
Eomamenchisaurus 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).
Discovery
The 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.
