Crichtonsaurus bohlini

(Bohlin's Crichton lizard)Etymology
Crichtonsaurus is derived from "Crichton" (for American author Michael Crichton who wrote, amongst other books, Jurassic Park) and the Greek "sauros" (lizard).
The species epithet, bohlini, honours Birger Bohlin, a Swedish paleontologist who took part in several paleontological expeditions to China during the 1930s. He described numerous Chinese ankylosaurs, and was part of the group that established the existence of "Peking Man" (Homo erectus pekinensis).
Discovery
The remains of Crichtonsaurus were discovered in the Sunjiawan Formation, Xiafuxiang, Beipiao, Liaoning Province, China, by Dong Zhiming in 1999.
The holotype (IVPP V12745) is a partial left lower jaw bearing three teeth, while referred specimens include two neck vertebrae and a back vertebra (IVPP V12746) and four sacral vertebrae, seven tail vertebrae, a shoulder girdle, an upper arm, a thighbone, foot bones, and various scutes and dermal armour (LPM 101).
A complete "Crichtonsaurus bohlini" mount at Sihetun Fossil Museum near Beipiao, China, may actually belong to Chrichtonpelta benxiensis. A cast of this same specimen is on display at Fukui Prefecture Dinosaur Museum, Japan.
