A pedunculate brachiopod population preserved in situ (Late Maastrichtian, NE Belgium)

The in situ preservation of a population of the pedunculate micromorphic brachiopod Aemula inusitata STEINICH, 1968 is highly exceptional. The substrate is a test of a holasteroid echinoid ( Echinocorys gr. conoidea ) from the Lixhe 1 Member (Gulpen Formation, Upper Maastrichtian) of Haccourt (Liège, NE Belgium), on which Aemula is associated with various adnate molluscan and bryozoan species. The palaeoecology of this population of Aemula inusitata is discussed.
