Abstract: Fifteen sediment samples were collected from estuarine environment of Nagavali River Estuary and 237 foraminifera belonging to 23 species have been identified in the sediment samples. Faunal diversity 23% and distribution are 42% in this estuary. Q-mode cluster analysis revealed that the foraminifera could be grouped into 4 clusters. The Ammonia tepida, Noniondepressulum, Quinqueloculinaseminulum, Ammonia beccarii, Quinqueloculinasp., Nonionsp., are abundant species. Occurrence and distribution of foraminiferal assemblages studied in the Nagavali estuary sediments, infers that these sediments were deposited from marine to brackish environment.
