Abstract:
A new stratigraphically useful Neogene diatom species Thalassiosira castanea Akiba et Yanagisawa is described. The species has a very short range in the lower part of the Upper Miocene Neodenticula kamtschatica - Nitzschia rolandii Subzone (NPD 7Ba) of the N. kamtschatica Zone (NPD 7B). The first occurrence of this species is coincident with the boundary between this zone and the underlying Rouxia californica Zone (NPD 7A), and hence it is a good marker for this boundary. Thalassiosira spinosa Schrader (1976), a species which bears a close resemblance to Thalassiosira castanea n. sp., is a later homonym of Thalassiosira spinosa Simonsen (1974), and therefore it is herein renamed Thalassiosira spinoconvexa Akiba et Yanagisawa nom. n.
