The new anthaspidellid taxon Brevaspidella dispersa is erected for specimens recovered from the Late Ordovician sponge assemblages of the island of Gotland, Sweden and the Dutch-German border region. In the latter area, they are collected from Early Pleistocene fluvial deposits of the Baltic River System, whereas those from Gotland are part of Late Pleistocene glacial or fluvio-glacial deposits. The provenance of both assemblages is uncertain, but they probably originated from an Ordovician basin in the northern Baltic Sea or the Bothnian Gulf, west of Finland. As yet, Brevaspidella dispersa gen. et sp. nov. is restricted to the Gotland-German-Dutch sponge association and has not been found in the assemblage of nearly-coeval ‘lavender-blue cherts’ and ‘blue sponges’. The new taxon is closely related to the genus Anthaspidella, but differs in the aquiferous system and in having a well developed concentrically wrinkled dermal layer. ; The 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.
