Abstract
A large number of fossil plants were collected from the Lower Cretaceous Youngdong Group in the Youngdong area of Chungcheongbug-do, Korea. Youngdong flora consists of 5 genera and 6 species, such as Frenelopsis cf. alata, Pseudofrenelopsis cf. parceramosa, P. cf. varians, Brachyphyllum cf. vulgare, Pagiophyllum sp., and Classostrobus sp., including the male and female cones of Pseudofrenelopsis first occurred in the study area. All of them belong to conifers of Cheirolepidiaceae. It is presumed that Youngdong flora might have flourished under the arid subtropical climate during the middle-late Early Cretaceous.
