WebA reappraisal of available information concerning fossil species of the genus Bouchardia Davidson 1850 reveals occurrences in various stratigraphic units ranging from about the uppermost Cretaceous-Palaeocene boundary to the Mio-Pliocene. Whereas the genus has not been reported from certain late Tertiary marine units of southern Patagonia, it does … WebThe extent of racemization of aspartic acid (Asp) has been used to estimate the ages of 9 shells of the epifaunal calcitic brachiopod Bouchardia rosea and 9 shells of the infaunal aragonitic bivalve Semele casali. Both taxa were collected concurrently from the same sites at depths of 10 m and 30 m off the coast of Brazil.
