The abundant faunal remains from the Takarkori rock shelter in the Tadrart Acacus
region of southwestern Libya are described. The material that covers the period
between 10,200 to 4650 years cal BP illustrates the more humid environmental
conditions in the Central Sahara during early and middle Holocene times. Particular
attention is focussed on the aquatic fauna that shows marked diachronic changes
related to increasing aridification. This is reflected in the decreasing amount of
fish remains compared to mammals and, within the fish fauna, by changes through time
in the proportion of the species and by a reduction of fish size. The aquatic fauna
can, in addition, be used to formulate hypotheses about the former
palaeohydrographical network. This is done by considering the possible location of
pre-Holocene relic populations combined with observations on the topography and
palaeohydrological settings of the Central Sahara.
