Amaurellina sinuosa (d’Orbigny, 1850)

Fig. 7G–I .

Stratigraphic and geographic range.—Early Eocene, Ypresian (Cuisian) (PB).

Colour pattern description.—The residual pattern consists of three levels of residual colouration. The background is heterogeneous with thin fluorescent spiral stripes and the apex is pale. There are two straight stripes and the adapical one is sometimes distinguishable on the penultimate whorl ( Fig. 7G 2 , I). Both stripes have constant and similar width.
