Distinguishing features: Small (3-5 µm) Eiffellithus, cross-bars axially aligned, terminations simple


Morphology: "A small species of Eiffellithus in which the small, indistinct central cross is axially aligned. The inner cycle fills the central area. Differentiation: This new species is easily distinguished from E. eximius, which is much larger, and has a distinctive, bifurcating cross that takes up more of the central area. Furthermore, E. lindiensis ranges up into the Maastrichtian. It is distinct from other Late Cretaceous eiffellithids in being small and having an axial cross." [Lees 2007]

Size: The size is not specified in the original diagnosis but the holotype is 4.4µm long and illustrated specimens are 3-5µm.
