Macrofossil content from the Miocene part of CRP-1 core, Cape Roberts (Victoria Land Basin) is scant and mostly limited to a few pectinid bivalves and serpulidpolychaetes. Selective diagenesis has seriously affected the Miocene sediments, probably biasing the fossil legacy which is dominated by a reduced number of calcitic tests. Pectinid bivalves pertain to two different taxa ascribed to”Chlamys”. The serpulid is an undescribed species which likely lived gregariously. The maciofauna may have lived at a relatively shallow depth in a siliciclastic shelf under conditions that were riobably somewhat warmerthan those in the present Ross Sea.
