Cocculus lottii was named by Collinson et al. (2012) [Endocarp bisymmetric, dorsiventral length 9.2–9.6 mm, width 9–10.5 mm (n = 4), slightly laterally flattened, almost circular in lateral view with very broadly rounded dorsal surface, no dorsal crest but with a groove in the plane of bisymmetry; base convex to almost straight. Central depression small (up to 2.2 mm in diameter) reniform to subcircular, present on each lateral face but does not penetrate completely (i.e. not forming a foramen). Central condylar area surrounded by an incomplete annular bulged area which covers at least two thirds the distance from the central depression to the periphery. This is surrounded by a narrow, poorly developed groove separating it from a peripheral bulged ridge adjacent to the margin. Both lateral and peripheral bulges ornamented with irregularly arranged radiating fine and coarse rugulae, mostly transversely arranged, sometimes extending into short spines.]. It is considered to be a form taxon. Its type specimen is Holotype SM.B Me 8559, a seed/fruit, and it is a compression fossil. It is the type species of Cocculus.
