A large tooth of theropod dinosaur that was recovered from the Hasandong Formation (Lower Cretaceous; Aptian-Albian) in Daedo island, Hadong Couty, South Gyeongsang Province of South Korea is redescribed. Although the tooth was misidentified as a "Prodeinodon"-like megalosaurid theropod at the first time, detailed comparisons with known theropod dentition anatomy strongly indicate that this tooth belongs to an Acrocanthosaurus-like basal carcharodontosaurid theropod. This referral is supported by its combination of large size, ovoid-shaped cervix outline, mesial carina that does not reach the cervix, labially displaced distal carina and large number of denticles. This tooth is different from other carcharodontosaurid teeth from the same formation in several anatomical aspects (e.g., smaller overall size, presence of transverse lines adjacent to the distal carina, presence of interdenticular sulci in distal carina, denticle densities, crown basal ratio), indicating that carcharodontosaurid diversity in the Early Cretaceous of Korea could have been higher, although these differences may represent positional or individual variations. The presence of Acrocanthosaurus-like theropod teeth (e.g., "Prodeinodon", "Wakinosaurus") from early Cretaceous deposits (Valanginian-Cenomanian) of South Korea, Japan, Mongolia and China indicates that North American Acrocanthosaurus atokensis possibly represents a form that immigrated from the Asia.

Abstract. The non-marine ostracod genus Frambocythere Colin, 1980 (Limnocytheridae, Timiriaseviinae) had a previously known stratigraphical range from the Albian (Lower Cretaceous) through to the Lutetian (middle Eocene). However, during surveys of Seongryu Cave in Uljin-gun Province, South Korea, specimens of an extant species of Frambocythere were recovered. This extends the stratigraphic range of the genus by more than 40 million years to the present, and the species is, therefore, considered to be a relict ‘living fossil’. This newly described species is most similar in morphology to Frambocythere gr. tumiensis (Helmdach, 1978), reported from Thanetian (Paleocene) deposits of the Paris Basin. The living species was found in the hypogean realm, in contrast to the fossil species, which were all epigean. It is hypothesized that, like the genus Kovalevskiella Klein, 1963, which belongs to the same lineage, Frambocythere migrated from epigean to hypogean habitats.
