摘要：
An unusually severe drought in 1982 led to a temporary die-off of elephants at a natural water source in Hwange National Park, Zimbabwe. Compared to living populations, the age structure of the animals killed by drought is strongly biased toward 2- to 8-yr-old animals. The fresh carcasses of these young elephants were commingled with weathered remains of adults that had died earlier, creating a mixed skeletal sample whose age structure was much closer to that of living populations. Observations of elephant bones that have accumulated due to natural mortality at water holes might provide analogs for paleocological interpretations of fossil proboscidean assemblages.
