Abstract. Cheilostome bryozoans (Phylum Bryozoa; Order Cheilostomata) originated in the latest Jurassic but remained at low diversity until the late Albian–early Cenomanian, when they began an explosive radiation that has continued to the present day. Most knowledge of Late Cretaceous cheilostomes comes from Europe and the USA from deposits associated with the western Tethys Ocean. Only a few previous records of Cretaceous bryozoans exist from the margin of eastern Asia in the NW Pacific. We…

Colonial animals are structural individuals, subdivided into repeated morphological modules, which can individually acquire, process, and share resources, and serve as a living laboratory of evolutionary conflict and its mediation.


A mid-Cretaceous (Albian–Cenomanian) shell-rubble bryozoan fauna from the Goshoura Group, Kyushu, Japan
It is demonstrated that bryozoan assemblages worldwide were not of similar composition at the onset of cheilostome radiation, and underscores the need for further work in less studied regions.

Pre-Cenomanian Cheilostome Bryozoa: Current State of Knowledge
The presence of Late Albian neocheilostomes in both Europe and North America implies that their brief larval life was not an obstacle to achieving a wide distribution and suggests a role for rafting in their dispersal.
Phylogenetic significance of a new cheilostome bryozoan species, Dysnoetocella : voigti from the Upper Cretaceous Izumi Group in Shikoku, Japan
A new anascan cheilostome bryozoan species, Dysnoetocella? voigti, is described from the Upper Cretaceous Izumi Group in the northwestern part of Shikoku Island, Japan. The zoarium is erect and
Bryozoa of the Early Eocene Tumaio Limestone, Chatham Island, New Zealand
A previously unstudied bryozoan fauna from the Tumaio Limestone of Early Eocene age on Chatham Island is described, totalling 77 species (22 Cyclostomata, two CtenostomATA and 53 Cheilostomati) and the following new taxa are introduced.
Systematics of Upper Cretaceous calloporid bryozoans with primitive spinose ovicells
The discovery of similar multispinose ovicells in a third group, calloporids, which are closely related to primitive cheilostomes that do not brood their larvae is reported, which provides a link between Distelopora and more typicalCheilostome oviceLLs.
