In the spring of 2021, Deep Time Agency traveled to various archaeology museums in the Netherlands in order to retrace fossils that originate from the ENCI quarry. These were documented using drawings, which were then used to replicate the fossils, using cement from the ENCI factory. By doing so, we used the last bags of the ENCI cement from the quarry in Maastricht in a ceremonial way. During a workshop in the quarry, we involved students from the Maastricht Institute of Arts, whom we invited during a minor to help us in the production of the fossil replicas.
