Clypeina? Tekini sp. nov. (Dasyclada lean green Algae) from the Early Eocene in the Eskiehir Region (Western Central Turkey)

Abstract

A new Dasycladalean alga, Clypeina? tekini sp. nov. is described from the Lower Eocene sediments of the 5eyitgazi Region, southern Eskiehir central Turkey The elongated, compact calcareous skeleton of this species consists of regularly spaced horizontal whorls with pores of branches, a smooth inner surface and a networked outer skeleton surface. The laterals are of bowling-pin form with a smaller proximal and a larger sub-spherical distal swelling forming the cortex. The species occurs in a rich algal and larger benthic foraminifera (especially alveolinids) association. Clypeina? tekini sp. nov. and species showing a similar structure of the branches, form a special category of species within the genus Clypeina (Michelin 1845), characteristics of which at least are of infra -specific rank.
