| Abstract |
Macoma balthica is found first in the late Baventian of Mundesley, Sidestrand, West Runton and Sheringham, in Norfolk. It occurs by derivation in Pastonian sites close to these, but not elsewhere in the East Anglian 'Crag' succession. An hypothesis is offered, explaining this on tectonic grounds. Records of M. balthica from the Calabrian of Italy and the 'Icenien' of Holland are considered incorrect. A brief discussion of the paleogeography and immigration times of M. obliqua, M. praetenuis and M. calcárea is also given. |
