Abstract

The lacustrine Lagerstätte of Menat (Puy-de-Dôme, France) provides a unique window into the terrestrial Paleocene environments of Western Europe (Wedmann et al., 2018). It has shown an exceptional diversity of plants (leaves, flowers, seeds, pollen), and animals (vertebrates and arthropods, especially insects) (e.g., Piton, 1940). Wappler et al. (2009) made a first analysis of the animals-plants interactions. Recent extensive researches were made, allowing to collect an important set of leaves with numerous and diverse traces of activities, some of them being not previously recorded among the total of 1,130 specimens of leaves, fruits and flowers studied by Wappler et al. (2009). Among the new material, we found three curious sets of traces on a small leaf that do not correspond to anything previously listed by Labandeira et al. (2007). These traces can be attributed to the beetle subfamily Donaciinae (Chrysomelidae).
