One of the advantages of the outstandingly preserved sequence of marine sediments now exposed along the coastline between Hāwera and Whanganui, especially with the nicely datable layers of volcanic ash added whenever the Taranaki volcano and its predecessors went bang, is that you can trace the evolution of scallop species over millions of years.
