ABSTRACT
A new species, Clypeina teakolarae, is described from the Lower Eocene of Čičarija, in Slovenia. The pattern of calcification, known so far only from the Upper Jurassic and the Lower Cretaceous, is structurally equal to that of the Clypeina jurassica group of species, having an intracellular, radial-fibrous calcite infilling and a micritic cell wall. Contrary to other species of the C. jurassica group, the main stem of the new taxon consists of spaced out twinwhorls bearing numerous, commonly irregularly arranged laterals.
