Abstract: | Malayomaorica malayomaorica is an important Upper Jurassic bivalvein the southern hemisphere: widely distributed in strata ofEarly - Middle Kimmeridgian age, it is a zone fossil of considerablepotential for regional biostratigraphic correlations. Its commonoccurrence in the Latady Formation of the Orville Coast, Antarctica,indicates that at least part of this stratigraphic unit hasa Kimmeridgian age. Although its precise taxonomic status remainsin some doubt, it would appear to be the earliest buchiid-likebivalve so far recorded from the southern hemisphere. Its verywide distribution around the margins of Gondwana is similarto that established for species of the Late Jurassic bivalvegenera Retroceramus, Buchia and Anopaea (Received 13 April 1981; |
