Bienosaurus Dong, 2001
(Mesozoic vertebrate life. Indiana University Press Bloomington & Indianapolis: 238 NcZ) "Bien's lizard"
BYEN-o-SAWR-us ((M. N.) Bien + Gr. sauros "lizard")(m) named to honor the Chinese geologist and paleontologist Mei Nien Bien [Bian Meinian] "who collected the holotype" while working in Yunnan Province between 1938 and 1939 (Bien later moved to the United States). Bienosaurus is a small scelidosaur based on a nearly complete right lower jaw and skull fragments (Holotype: IVPP V 9612 (Institute of Vertebrate Paleontology and Paleoanthropology, Beijing)), found in the Early Jurassic (Hettangian-Pliensbachian) Dark Red Beds in the Lower Lufeng Formation, Lufeng Basin, Yunnan Province, China. The teeth show characteristics of both ankylosaurs and stegosaurs; the dentary is thick with a strongly curved tooth row. Small bony scutes are fused to the frontal and supraorbital bones. The skull was probably around 65-70 mm (2.5-2.8 in) long, suggesting a total body length of around 1 meter (40 in).
Type Species: Bienosaurus lufengensis [loo-fuhng-EN-sis] Dong, 2001: for the Lufeng Basin, where the specimen was found in Yunnan Province, China. Note that early media reports in November, 2000 indicated that the type species name for Bienosaurus would be "crichtonii" to honor Michael Crichton, the author of Jurassic Park. Dong does not indicate why he decided to change the official type species name to "lufengensis" instead. Thyreophora Scelidosauridae Early Jurassic (Hettangian-Pliensbachian) China
