•The sapropelite strata in the vicinity of Boltyshka village are overlain by deposits of the Kiev Svita (= “Formation”), which is dated as middle Eocene on the basis of its foraminifera (Ryabokon’ 2002). The underlying, sapropelite part of the core samples has been dated as late Paleocene–early Eocene based on its molluscs, ostracods, insects, and fishes (Stanislavskiy 1968; Sytchevskaya 1986). The sapropelite strata are composed of three units: the upper unit (thickness up to 55 metres) lacks vertebrate fossils; the middle unit(thickness up to 130 metres) contains rare teleost fossils in its lower part; and the lower unit (known thickness at least 270 metres) contains most of the teleost and all of the salamander fossils.
