Lepraliomorph bryozoans from Holocene deposits along the Konkan Coast of Western India

Abstract

To date, there is no published information on the Holocene bryozoans from India. In this study, we describe 10 species of lepraliomorph bryozoans collected from Holocene rocks along the Konkan coast between Maharashtra and Goa in western India. One of these species is new to science: Mucropetraliella malwanensis sp. nov. Five species are already known from elsewhere but are reported from India for the first time; four species are retained in open nomenclature because of insufficient material. These bryozoan assemblages likely inhabited warm water tropical to subtropical environments with euhaline to euryhaline salinities. The regional relationships show Indo-Pacific affinities.
