Koreanosaurus (lit. 'Korean lizard') is a genus of orodromine neornithischian dinosaur. One species has been described, Koreanosaurus boseongensis.
Y
Description
Koreanosaurus was a relatively small dinosaur, reaching 2–2.4 meters (6.6–7.9 ft) in body length.[2][3] Based on its taxonomic position and the existence of small burrows from the Seonso Conglomerate, Koreanosaurus is likely a burrowing dinosaur.[4] Unlike its orodromine relatives, Koreanosaurus is assumed to have been a quadruped.[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.[4] Han et al. found it plausible that Koreanosaurus might be a member of Jeholosauridae or closely related to it.[6]
