Abstract
A single tooth of the sand tiger shark, Carcharias sp., was collected from the upper Eocene Kusto svita in the Zaysan basin of northeastern Kazakhstan. The Kusto svita is nonmarine lacustrine strata with an ext ensive nonmarine biota of plants (especially charophytes) and terrestr ial vertebrates (especially mammals). The shark tooth was apparently c arried to the site by a predator/scavenger from the then-nearest seawa y, more than 500 km to the northwest.
