Abstract
One of the authors, E. Kitabayashi, has excavated more than 16,000 cyprinid and cobitid fossils of pharyngeal bones and teeth. Among them, we have identified 198 fossils. They consist of cobitids and six subfamilies, Danioninae, Cultrinae, Acheilognathinae, Leuciscinae, Gobioninae, Cyprininaeo of cyprinids. Danionine fossils contained two genera Nipponocypris and Zacco, cultrine ones were identified as genus Culter, acheilognathine ones contained two genera Acheilognathus and Tanakia, leuciscine ones contained two genera Phoxinus and Tribolodon, gobionine ones contained five genera Coreius, Squalidus, Gnathopogon, Hemibarbus, and Pseudorasbora, and cyprinine ones were genus Carassius. This fossil assemblage detected with water sieve method was more diverse than previous ones (Nakajima and Kitabayashi, 2001).
