Scott, L. 1996.
Palynology of hyrax middens: 2000 years of palaeoenvironmental
history in Namibia.
Quaternary International, Vol. 33, pp. 73-79.
http://dx.doi.org/10.1016/1040-6182(95)00093-3
Well-preserved and dateable faunal middens in rock shelters of
dry areas in southern Africa occur as desiccated urine-rich masses.
Under local conditions, which exclude microbial decomposition
and oxidation, urine cements together faecal pellets and other
inclusions. Nine radiocarbon dated hyrax (Procavia capensis)
dung middens from the Kuiseb River Basin of the Namib Desert
were sub-sampled and analysed for fossil pollen. Some contain
small proportions of rat droppings, but not many macro-fossils.
Comparative modern pollen in faecal samples were also studied.
Most plant macro-fossils are severely digested, but seeds
are well-preserved. Some insect inclusions were identified.
Small scale changes in vegetation over the last two millennia
were observed, representing environmental fluctuations in cycles
of ca. 100-200 years. The fluctuations partly agree with other
palynological data from southern Africa and with geomorphologic
evidence for environmental changes in the desert region.
STUDY NOTES: 2000 year pollen percentage record from 9 Hyrax middens
collected in the Kuiseb River Basin, Namibia.
Kuiseb River Basin, Namibia: ~23°25'S, ~15°15'E
