Abstract

An exploratory borehole cross-cutting Miocene deposits near Derezna (south of Kučevo town, Eastern Serbia) has intercepted Lower Cretaceous carbonate rocks in its lower part. The identified microfacies and micropaleontological associations indicate a Barremian age for these limestones. Among the identified dasycladalean algae, Salpingoporella patruliusi Bucur, a generally rare alga, is here recorded in relatively high abundance. Its occurrence is recorded for the first time in Serbia. Similiclypeina aff. somalica (Conrad et al.) is another dasycladalean species identified for the first time in the region. Its presence allows us to make some remarks concerning the two genera Similiclypeina and Piriferella.
