The early rudist bivalve Valletia antiqua Favre in Joukowsky & Favre, 1913 is recorded for the first time from the Tithonian to Berriasian tramberk Limestone (northeastern Czech Republic) and Ernstbrunn Limestone (Lower Austria). The species is re-described and its spatial distribution and stratigraphical range are outlined. Furthermore, the palaeoecology of Valletia antiqua is discussed in the light of novel data on palaeocommunities and microfacies, habitat selection and intraspecific competit
