The Earth system is enduring a unique transition in its history due to the pregnancy of human activities on geological processes compared to natural controls. A largescientificcommunity examines the extent to which these activities will be archived in the sedimentary record and remain for millions years within a new geological era named Anthropocene. Here we explore the potential of sediments that accumulated in sewer systems for such a record of human posterity, considering that urban socio-ecosystems are prone to a large diversity and high concentrations of potential tracers of human activities
