Abstract

Peripheral test wall flexure is developed in an upper Santonian-Maastrichtian lineage of serial planktonic foraminifera (Family Heterohelicidae Cushman, 1927). This lineage consists of two genera, Hendersonia nov. gen. and Paraspiroplecta nov. gen. Hendersonia (Upper Santonian-Campanian) includes three biserial throughout species, namely H. hendersoni nov. sp., H. carinata (Cushman, 1938) and H. jerseyensis nov. sp. This lineage shows the gradual development of the peripheral test wall flexure. Paraspiroplecta (Upper Campanian-Maastrichtian) presents early planispiral coil and weakly developed, probably relict, peripheral test wall flexure.
