• 論文の詳細を見る

• A new Neogene diatom species, Azpeitia komurae is described on the basis of both light and scanning electron microscope observations. The species is similar to A. nodulifer (A. SCHMIDT) FRYXELL & SIMS, but is distinguished by having a subcentral hyaline area. Its occurrence is restricted to the uppermost part of the Upper Miocene Rouxia californica Zone (NPD 7 A) of AKIBA (1983,1986) in the North Pacific, and hence it is a good marker species to recognize the horizon.
