Minylitha convallis Bukry 1973
Description: Plate-like rhomboidal nannoliths, with a raised rim on both sides. Acts as a single crystallographic unit with the optic axis nearly perpendicular to the plate.
Remarks: In plan view M. convallis shows only low birefringence and is easily overlooked. The dog-bone like side view, first described by Theodoridis (1984), is more distinctive and makes identification unambiguous.
The affinities of this species are unknown, but since it is formed of a single crystallographic unit it may be related to the Triquethrhabdulaceae.
