Morphometric analysis of benthic foraminifera ammonia from chilika lake, Odisha, India

Abstract

This dissertation concerns with the study of Ammonia from Chilika Lake, Odisha. Morphologically, three species of Ammonia i.e. Ammonia beccarii, Ammonia tepida and Ammonia parkinsoniana were identified. The morphometric parameters were measured by Image Analysis System. Cluster analysis, performed on the morphological data set (e.g. greatest spiral diameter, umbilical diameter, proloculus diameter, radial sutural furrow length etc.). Based on those observations, three different species of Ammonia has been identified.
