Abstract
The present paper documents nine geniculate coralline algal species, namely Arthrocardia cretacica, Calliarthron antiquum, Corallina hayasaki, C. marshallensis, C. prisca, C. typica, Jania mengaudi, J. sripadaraoi and J. vetus from Neogene-Quaternary sediments of Porbandar area, Saurahtra, Gujarat. Out of nine species, six species namely Arthrocardia cretacica, Calliarthron antiquum, Corallina hayasaki, C. marshallensis, C. prisca and C. typica occur in the Dwarka Formation (lower-middle Miocene), one species Jania sripadaraoi occurs in the Adatiana Member of the Miliolite Formation (early middle-late Pleistocene) and two species namely, Jania mengaudi and J. vetus occur in the Porbandar Calcarenite Member of the Chaya Formation (late Pleistocene-late Holocene). These species indicate that the Dwarka Formation and the Adatiana Member of the Miliolite Formation were deposited in tropical marine environment with moderate to low energy conditions at depths ranging from intertidal to 60 m, and that the Porbandar Calcarenite Member of the Chaya Formation was deposited in a tropical marine environment under moderate to low energy conditions at depths ranging from 40 m to 60 m.
