Our research integrates new lithic analyses with recent micromorphological and paleontological data, offering a comprehensive understanding of the site's occupational history. Radiometric recalibration of existing dates, combined with comparative analyses of other high-altitude Neanderthal sites, refines the chronological framework of these occupations in a late phase of the Middle Paleolithic. Although sparse, the lithic assemblages from Caverna Generosa provide valuable insights into Neanderthal technological behaviors. The pronounced fragmentation of the reduction sequence, along with the presence of end-products, indicates a level of planning and mobility consistent with hunter–gatherer strategies in challenging environments. These results contribute to broader discussions on Neanderthal toolkits and adaptations to high-altitude habitats, highlighting the complexity of their subsistence strategies and settlement patterns.

The new tephra has two glass populations and is matched to the ~322 ka Matahina caldera-forming eruption. High-resolution sampling of peat bracketing the KOT and Rangitawa Tephra reveals marked changes in local vegetation following the deposition of both tephras.

The oldest faunas, dated to the Muchkap (MIS 15) and Likhvin (MIS 11) interglacials, belonged to the Late Tiraspolian and Gun'ki small mammal complexes, respectively. Later faunas, corresponding to the Kamenka, Romny, and Mezin paleosols, included chronotaxa morphologically close to modern species. The youngest Middle Pleistocene fauna most likely correlates with the Romny interglacial (MIS 7). The youngest overall fauna dates to the Bryansk (=Denekamp) interstadial (late MIS 3). We performed the first comprehensive analysis of the quantitative composition of these faunas using multivariate analysis and inferred qualitative relationships among them. The main component of variation in faunal composition identified by non-metric multidimensional scaling (first NMDS axis) reflects evolutionary changes in the phyletic lineages of steppe lemmings (<i>Lagurus</i>) and narrow-headed voles (<i>Stenocranius</i>). The other two components correlated with the geographical position (longitude and latitude, respectively) of the sections, most likely reflecting a relatively stable pattern of variation in ecological conditions across the East European Plain. The faunal composition suggests that the animals inhabited semi-arid and arid steppe habitats, and that the paleosols formed during the warmest and driest phases of the interglacials in Eastern Europe. The non-analog Bryansk interstadial complex is associated with conditions of periglacial, mosaic steppe–tundra-like environments.
