ISSN 0311-5518A well-preserved single left valve of a large oyster embedded in coarse volcaniclastic sediment and identified asCrenostreasp. cf.C. cannoni(Marwick, 1928) was dredged from east of Heard Island, central southern Indian Ocean. It is accompanied by a fragment of the pectinid bivalveAustrochlamyssp. indet. and foraminifera.Austrochlamyssp. indet. and other bivalve fragments were analysed for87Sr/86Sr, δ18O and δ13C, the results yielding an age of 17.5 Ma (later early Miocene) and a water temperature ofca10°C. Foraminifera and sediment characteristics indicate that accumulation occurred in mid-continental shelf depths, at a location where nutrient supply was good.Patrick G.
