These taxa were examined under the scanning electron microscope, which has helped to explain their morphological descriptions and assign them a taxonomic classification. The taxa have rare and sporadic occurrences at Hole 716A and thus we do not know their potential in paleoceanographic and paleoclimatic reconstructions, which requires further studies from other parts of the Indian OceancompletedInvertebrate paleontologyAcostinella sahaiiAdelosina bhallaibenthic taxaCenozoicfaunal studiesForaminiferaHofkeruva sahaiiIndian OceanInvertebrataLeg 115Maldives Ridgemarine environmentmicrofossilsmorphologynew taxaOcean Drilling ProgramODP Site 716paleoenvironmentPleistoceneProtistaQuaternarySEM dataSiphonaperta bhallaitaxonomyTriloculinella bhallaiupper Pleistoceneurn:org.iodp:exp:115urnlargerWorkCitationcampaignurn:org.iodp:exp:115:site:716urnlargerWorkCitationstudyurn:org.iodp:exp:115urnlargerWorkCitationcampaignEnglishgeoscientificInformation73.170073.17004.56004.5600
