Abstract: A new ichnogenus and ichnospecies Saronichnus abeli is described for a protrusive trace fossil produced by the lucinoid bivalve Thyasira michelottii from storm-dominated siliciclastics of the Miocene (Lower Badenian) Grund Formation. A chemosymbiotic life strategy under dysaerobic conditions is proposed for this bivalve. The trace fossil expresses an adaptation to oxygen-poor habitats.

Keywords: Miocene, Austria, chemosymbiosis, molasse, trace fossils, Thyasira
