The section of Garbova de Sus contains diverse fossil groups and rich bryozoan assemblages, with 77 species altogether. Several taxa have been recognized as very important in the assemblage and two new taxa are described in detail: Poricella garbovensis sp. nov. and Therenia transylvanica sp. nov. Foraminifera and calcareous nannofossil assemblages were used for biostratigraphic and paleoenvironmental interpretations. On the basis of sedimentological features and micropaleontological data, the sequence of paleoenvironments can be subdivided into two intervals indicating slightly different climatic conditions.
