In 2003, three specimens of
Koreanosaurus were found in the
Late Cretaceous-age
Seonso Conglomerate from the southern coast of the Bibong-ri dinosaur egg site,
Boseong,
Korean Peninsula. These specimens include the
holotype KDRC-BB2, a partial upper skeleton lacking the skull, and two additional specimens which contains portions of the pelvic girdle and lower leg (KDRC-BB1 and KDRC-BB3). The
type species was named after its locality (
Boseong site 5). This taxon was initially named and described in a
master's thesis by Dae-Gil Lee in 2008, and was officially published by Min Huh, Dae-Gil Lee, Jung-Kyun Kim, Jong-Deock Lim and
Pascal Godefroit in
2011. == Description ==
