Diversity and biolithostratigraphy of foraminifera from the upper Eocene–lower Oligocene Malishka section, Armenia

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.
