Koreanosaurus (meaning "Korean lizard") is a genus of orodromine neornithischian dinosaur. One species has been described, Koreanosaurus boseongensis.
Description
Because of the "minority of skeleton" remains, its adult size is uncertain,[1] but Huh et al. estimated at up to 2.4 meters (7.9 ft) in length.[2] Thomas Holtz later gave a length estimate of 2.1 m (6.9 ft) and a mass estimate as that of a wolf which would be approximately 40 kg (88 lb).[3] Unlike its orodromine relatives, Koreanosaurus is assumed to have been a quadruped.[4]
Discovery
In 2003 three fossils of Koreanosaurus were found in the Late Cretaceous-age Seonso Conglomerate from the southern coast of the Bi-bong Dinosaur Fossil Findspot, Boseong, Korean Peninsula:[2] the holotype KDRC-BB2, a partial skeleton lacking the skull, and the paratypes KDRC-BB1 and KDRC-BB3.[5] The type species is Koreanosaurus boseongensis, after its discovery locality (Boseong site 5). The type species was initially named and described in a master's thesis by Dae-Gil Lee in 2008,[6] and was officially published by Min Huh, Dae-Gil Lee, Jung-Kyun Kim, Jong-Deock Lim and Pascal Godefroit in 2011.[5]
Classification
Koreanosaurus was considered to be a basal member of the Ornithopoda by the authors, forming a clade with Zephyrosaurus schaffi, Orodromeus makelai and Oryctodromeus cubicularis from which they deduced a burrowing lifestyle.[5] Han et al. found it plausible that Koreanosaurus might be a member of Jeholosauridae or closely related to it.[7]
