Statistical and morphological analysis of tanatocenosis microbiota of the Lakhta lowland is carried out in this article. During the study of bottom lake sediments for this object the dominant zooindicator represented by numerous remains of Cladocera branchiopod crustaceans was identified in sediments. For the first time, a statistical calculation of microfauna distribution in the samples was made for the water body in question, as well as the morphology of the studied fossils was described and preliminary paleoecological conclusions were made.
