The results of micropaleontological research of sponge spicules and foraminifers from the Callovian sediments in the north-west part of Dnieper-Donets depression are showed here. Spicules of sponges and foraminifers complexes of Lower, Middle and Upper Callovian sediments are described. Analysis of foraminiferal complexes allowed to allocate foraminiferal zones (Lower Callovian ‑ zone Haplophragmoides infracalloviensis; Middle Callovian ‑ zone Lenticulina cultratiformis – Lenticulina pseudocrassa and Upper Callovian ‑ zone Lenticulina tumida – Epistomina elschankaensis) and note their characteristics. New morphospecies of sponge’s spicules have been set in the study area for the first time. Analysis of sponges’ communities’ spicules enables us to assume that in the Middle and Upper Callovian basin there were sponges of Geodidae, Pachastrellidae, Tethyidae families of Tetraxonida type, and the Haliclonidae family of Cornacuspongida type. The presence of the Farreidae family sponges, Hexactinosa subtype, Amphiscophora type is also possible. In the Lower Callovian basin probably existed sponges of such families as Geodidae, Theneidae, Plinthosellidae, Haliclonidae, Axinellidae, of Hyalospongiae type and possible representatives of Amphiscophora type of Hyalonematidae family, as well as the Farreidae family of the Hexactinosa subtype. Gradual change of sponge spicules and foraminifers complexes is traced from the Lower Callovian to the Upper Callovian. The paleontological characteristics of the Callovian sediments are completed by the new data of spicule and foraminifera analysis. Ostracods and small bivalves in the complex are found. This allowed to study the biostratigraphic characteristics of the area supplement. The lithological characteristics and regularities of microfossils distribution made the existence conditions of sponge spicules, foraminifers, ostracods, bivalves small mussels possible in Callovian paleobasin reconstruction.
