M a t e r i a l. One specimen, chalcedony cast, USNM
PAL 772369.
D e s c r i p t i o n. Ovate-elliptic in lateral view, elliptic in cross-section, 5.5 mm high, 4.1 by 3.6 mm in cross section. Attachment end with a collar-like opening ( Text-fig. 8p, s View Text-fig ), 1 mm diameter, with a slight central depression surrounded by a two raised, concentric rings, each with a rounded margin bearing a faint hint of radially-oriented cells ( Text-fig. 8p View Text-fig ). The surface of the fossil marked by a faint papillate pattern suggestive of cells ( Text-fig. 8q, r View Text-fig ). Distal end rounded, without any distinctive markings.
D i s c u s s i o n. The short and long cross-sectional axes impart a bilateral symmetry to the structure, but there is no sign of a ridge or groove that would suggest a plane of dehiscence or raphe. The basal (?) scar is suggestive of a point of attachment. These features, coupled with a consistent surficial pattern indicative of cells, clearly indicate that this is a fruit or seed, but do not permit further attribution.
