摘要：For the first time a taxonomic composition of lithistid sponges which are lived in the Late Eocene basin of Verchovtzev depression Ukrainian Shield is supposed by the spicules morphological analysis. There are sponges of ten geneses and seven families presented in paleocoenosis, but families Theonellidae (geneses Lerouxia, Rhagadinia) andPlinthosellidae (genusPlinthosella) are dominated. Threenewmorphospeciesof spicules aredescribed: Phyllotriaenapartita T.A.Ivanova morphosp.n., Ph. araneola T.A.Ivanova, morphosp.n., Tetracrepides semiornatus T.A.Ivanova, morphosp.n. Their stratigraphical meaning is determined. These spicules are characteristic for the Obuchovian Suite and would be used as the paleontological criterion of the Obuchovian Suite determination in geological sections of the Middle Dnieper region. Key words: Porifera, Lithistida, spongiospicula, Upper Eocene, Obuchovian Suite, Ukrainian Shield, Middle Dnieper region.
