M a t e r i a l. One specimen, chalcedony cast, USNM
PAL 772372.
D e s c r i p t i o n. A broken half sphere, 10.9 mm in height and 9.7 mm wide, the thickness (through the broken portion), 5.4 mm. The surface is rough ( Text-fig. 9i View Text-fig ), although it is unclear if this is due to adherent minerals or represents the original condition. One end has a slight constriction suggesting a point of attachment ( Text-fig. 9i, j View Text-fig ); the opposite end is smoothly rounded. In cross section, a palisade layer of a single layer of elongate sclereids is preserved, ranging from 0.5 to 0.85 mm in thickness (Textfig. 9l, m). In places this has peeled off the exterior of the fossil. No further internal structure is present.
D i s c u s s i o n. The palisade layer of cells ( Text-fig. 9l, m View Text-fig ) indicates the botanical nature of this structure. The spherical shape, palisade layer of elongate cells and possible small point of attachment are reminiscent of the drupes of some Lauraceae JUSS. , but the material is not sufficiently well preserved to verify this assignment.
