Abstract
The fossil genus Clypeina (Michelin, 1845) comprises some 40 species. We describe a new representative from mid-Cretaceous strata of the Potiguar basin, Brazil, a form with closely set whorls of tubular, bended laterals. It is compared with Clypeina hanabataensis Yabe & Toyama 1949, a Late Jurassic species, and with Pseudoactinoporella fragilis (Conrad, 1970), an Early Cretaceous taxon. This species belongs to a short list of green algae found in the young South Atlantic oceanic corridor.
