Remark The taxon Rotorbinella hensoni is a basket to receive Paleocene to Ilerdian Rotorbinellas lacking features of specific character. The shells are smooth on both sides and exhibit almost radial, slightly curved ventral chamber sutures lacking any feathering. The umbilical pile forms a solid, undivided plug. There is a faint notch indicating the position of the foliar suture corresponding to the umbilical plate. The latter is positioned comparatively far from the umbilical pile and creates a broad spiral canal around the umbilical pile. The folia are large but do not overlap, nor do they fuse to form a columella. The intraseptal interlocular space is restricted to the ventral adaxial part of the septum where it creates a single, undivided room communicating with the umbilical space around the umbilical plug. [details]
