The petrified wood for this study was collected from the Upper Jurassic Morrison Formation in the south central part of Utah on the Colorado Plateau. The study area, located near Clay Point, Garfield County, Utah, is south of the Henry Mountains. The site is relatively undisturbed containing many well preserved specimens. This study constitutes the first detailed study of fossil coniferous woods of the Morrison Formation. Although this formation contains abundant petrified wood, its floral composition has been virtually unknown. Three genera have been identified in this study: Protopiceoxylon Gothan, Mesembrioxylon Seward, and Taxaceoxylon (Unger) Krausel. Protopiceoxylon has only been reported once before from strata of the Jurassic age in North America (Knowlton, 1900). Mesembrioxylon and Taxaceoxylon have not been reported previously from the Jurassic of North America.

This study set out to identify and interpret botanical remains from Historic Cave, Balerno Main Shelter and Balerno Shelter 2 in the Limpopo Province. Botanical remains were identified through comparative collections, and quantified through a raw count and presence analysis. They were interpreted through literature on plant uses in southern Africa. Over 12 500 remains were recovered from Historic Cave, almost 1 500 from Balerno Main Shelter and only five from Balerno Shelter 2. Remains from Historic Cave fell into food, water, storage and muti categories of use. Balerno Main Shelter revealed plants in the water and muti categories. Balerno Shelter 2 had too few remains. The study demonstrated that plant remains can shed light on why cave sites were occupied, as the assemblages reflect different plant uses. The remains from Historic Cave describe a society living and taking refuge in a cave under siege. Balerno Main Shelter may have been used for ritual purposes.
