Knowledge of Quaternary fossils in Namibia is poor, although several sites were identified by Hermann Korn and Henno Martin (Korn and Martin, 1937). The Ongongo Springs in Western Namibia are associated with thick layers of tufa (freshwater carbonate) containing a rich collection of impressions of macroscopic fossil plant leaves, roots, branches and trunks. The leaf impressions show mostly primary venation, making their identification difficult. The absence of organic material within the preserved leaves, roots, stems and trunks renders C14 dating impossible. Dating of tufas has been attempted in the past, but the results are not reliable as contaminations easily occur, due to their porous nature.At Ongongo a possible sedge leaf was noted as were impressions of the leaves of sycamore fig, Ficus sycomorus (Family Moraceae) and mopane, Colophospermum mopane (Family Fabaceae). However, no fruits or seeds were found. To date only a single vertebrate fossil has been reported by a visitor to the springs. It was suggested to be the impression of a frog skeleton. Land snails were observed in the tufas and surrounding calcretes and are comparable to the modern genus Sculptaria.
