Ignavusaurus rachelis

(Raquel's Coward lizard)Etymology
Ignavusaurus is derived from the Latin word "ignavus" ("coward", but can also mean "lazy") and the Greek "sauros" (lizard), not because it was any more of a scaredy-cat than other sauropodomorphs but because of its place of discovery — Ha Ralekoala — which literally means "The place of the father of the coward". We'll bet there is an interesting story behind the name, and we would love to tell you what that story is. Unfortunately no-one knows. Not even Fabian Knoll (pers.comm.) who actually named Ignavusaurus.
The species epithet, rachelis, honours paleontologist Raquel López-Antoñanzas of the National Museum of Natural Sciences in Madrid.
Discovery
The remains of Ignavusaurus were discovered in the reddish siltstone of the Upper Elliot Formation (Stormberg Group) at Ha Ralekoala, Quacha's Nek, Lesotho.
The holotype (BM HR 20) is a partial, well preserved articulated skeleton.
