| Abstract |
Onychocellidae (Bryozoa, Cheilostomatida) are one of the dominant components of the cheilostomatid bryozoan fossil assemblage in the Kallankurichchi Formation of the Ariyalur Group, Cauvery Basin, South India. The present study describes and illustrates eleven species of Onychocellidae from the sedimentary deposits of this formation. Among these, ten species are already known from these deposits, while one species is left in open nomenclature. Bryozoan fauna thrived during transgressional period indicating shallow marine environment and low sedimentation rate. |
