Abstract

The construction of regional biochronological scales for the Pleistocene based on remains of small mammals is a systematic and successive process of accumulation of informative data with their subsequent presentation in the form of schemes and tables. The geological and palaeontological characteristics of reference sections are presented in detail. Faunal assemblages and developmental phases in associations of small mammals in the south of Eastern Europe are described based on the taxonomic composition of Pleistocene micromammal fauna. Ortho- and parastratigraphic taxa are identified and phylogenetic trees are constructed based on modifications of morphological traits in the evolution of separate species. A macroevolutionary biochronological scale has been compiled using several types of biochronozones. A phenozone-based microevolutionary biochronological scale has been established for the Quaternary of the south of Eastern Europe. These scales can be used to subdivide Quaternary deposits of this region by identifying biostratigraphic units and correlating them on local and regional scales.
