| Abstract: | The first unequivocal insect remains from compression plant assemblages of the central German Leipzig Embayment (former Weißelster Basin) are reported and briefly described. The fossil taphocoenosis comes from the upper Bartonian or lower Priabonian Luckenau Clay complex (lignite-bearing Borna Formation) that represents sediments of coastal alluvial braidplain origin. Autecological interpretations of insect taxa are in accordance with plant-based environmental reconstructions as three of five insect taxa are closely related to freshwater environments. Based on the accompanying plant assemblage the palaeoclimate of the habitat is characterized as “subtropical” and humid, but with a distinctive seasonality in precipitation. |
