Key Points

Diversity of foraminifera supports insights into past ecological conditions in the upper Eocene to lower Oligocene periods.
Significant findings detail multiple genera and species, with evidence from layered sediment observations across the Malishka section.
Analysis of sediment layers highlights the importance of biolithostratigraphy in understanding geological timeframes and environments.
Findings underscore the role of foraminifera as key indicators of paleoenvironmental conditions during the transition from Eocene to Oligocene.
