This conference will be focused solely on bivalved molluscs, to be held 5th - 8th September, 2023, at the University of Cambridge (UK). This is intended as a successor to the previous bivalve meetings that took place in London (1977), Drumheller (1995), Cambridge (1999) and Barcelona (2006). Our aim is to host a relaxed, open in-person meeting to carry on this tradition of convivial review of all aspects of current bivalve research (living and fossil).
