AbstractThe Cenozoic bryozoan fauna of Indonesia has been neglected in the past. In this pioneering study, based on new material collected during the two field seasons of the Throughflow project, we describe a total of 51 bryozoan species, comprising 15 cyclostomes and 36 anascan-grade cheilostomes, ranging in age from Early to Late Miocene (late Burdigalian to Messinian), collected from 17 sections located in the vicinities of Samarinda, Bontang and Sangkulirang in East Kalimantan, Indonesian Borneo. Eleven of these species are new: Microeciella nadiae sp. nov., Pseudidmonea johnsoni sp. nov., Cranosina rubeni sp. nov., Parellisina mirellae sp. nov., Vincularia berningi sp. nov., Vincularia semarai sp. nov., Vincularia tjaki sp. nov., Vincularia manchanui sp. nov., Gontarella? sendinoae sp. nov., Canda giorgioi sp. nov. and Canda federicae sp. nov. Ten species show affinities with Recent taxa from the Indo-Pacific. Bryozoans are found mainly encrusting the undersides of platy corals from low- and high-relief build-ups, and coral carpets in mixed carbonate-siliciclastic environments.
