Five main bone surface colors were attributed to soil, sun, hemolysis, decomposition, and fungi. The presence of fungi on buried bones suggests a prior period of surface exposure. Cross-sections of bone that had been buried without any period of surface exposure were identical to the color of bones that had been initially buried and then subsequently exposed to surface elements. Minimal color staining was linked to the decomposition of excess tissue. The study proposes further research that will include two additional scenarios, simple burial and surface deposition, for comparison. Further, additional research should increase the time allotted for burial and surface exposure in order to determine how long it takes for bone to become sun-bleached and surface-stained, whether color staining is able to penetrate the cortex, and whether the patterns observed in the limited time frame of 4 weeks for each form of disposition is maintained in bone that is exposed to extended periods of sun bleaching and soil staining. Several other research suggestions are offered as well. Forty juvenile pig humeri with minimal tissue were used in each scenario, with an additional 20 controls used to determine whether decomposing tissue affected bone color. Munsell Color Charts were used to record color of bone surface and 2.5 cm cross-sections. 2 tables, 5 figures, and 26 references
