Early Cretaceous bryozoans are key to understanding the evolutionary radiation of order Cheilostomata, the dominant modern group. Prior to the current study, there were few records of any Cretaceous cheilostomes from eastern Asia, and no pre-Cenomanian records. We found bryozoan fossils to be common in brackish-water to marine deposits representing estuary–tidal-flat and shoreface–inner-shelf habitats in the late Albian–early Cenomanian Goshoura Group, Goshoura Island, Kyushu, Japan. Bryozoans… 
Cheilostome Bryozoa from the Upper Cretaceous Himenoura Group, Kyushu, Japan
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
Early Cretaceous gymnolaemate bryozoans from the early to middle Albian of the Glen Rose and Walnut formations of Texas, USA
TLDR
These formations therefore yield the oldest known bryozoan assemblage dominated in terms of biomass by cheilostomes, and the genus concept of Charixa is discussed and amended.
A new early Cheilostome bryozoan from the Aptian (Lower Cretaceous) of Valencia, Spain.
Cheilostome bryozoans are uncommon in Lower Cretaceous rocks. Therefore, the discovery of a specimen from the Upper Aptian of Fuente la Higuera, Valencia, warrants attention. Charixa sagnieri sp.
Early Cretaceous cyclostome bryozoans from the early to middle Albian of the Glen Rose and Walnut formations of Texas, USA
Abstract The Glen Rose and Walnut formations of southcentral and northcentral Texas comprise shallow-water carbonates deposited during the late Aptian to middle Albian on a carbonate platform. The
Apprehending novel biodiversity—fifteen new genera of Zealandian Bryozoa

TLDR
Fifteen new genera of cheilostome Bryozoa are described from the New Zealand biogeographical region, centred on Zealandia, from shallow coastal waters to abyssal depths, with plesiomorphies that are novel among Recent Calloporidae but which are found in some Cretaceous calloporids or cribrilinids.
Eocene isopods of Pesciara di Bolca (Italy) revisited
TLDR
Fossils of the cymothoidan Palaega acuticauda Secretan and the sphaeromatidean Heterosphaeroma veronensis Secretan are reinvestigated and it is argued that both species do not differ substantially in dorsal morphology from recent genera, and are placed among more likely congeners.
The earliest calcified opercula of bryozoans of the order Cheilostomata
The earliest known calcified opercula are described in cryptocystidean anascan cheilostome bryozoans: Onychocella inelegans (Lonsdale, 1850) from the Lower-Upper boundary beds of the Campanian of the

Pre-Cenomanian Cheilostome Bryozoa: Current State of Knowledge
TLDR
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.

MORPHOLOGICAL DIFFERENTIATION OF AVICULARIA AND THE PROLIFERATION OF SPECIES IN MID-CRETACEOUS WILBERTOPORA CHEETHAM, 1954 (BRYOZOA: CHEILOSTOMATA)
TLDR
The cladistic trees strongly suggest that most or all of the species diverged before the end of the Albian, but stratigraphic resolution is insufficient to test this hypothesis, and the series of morphological changes differentiating avicularia from ordinary autozooids in these species is highly significant statistically, and may be a pattern later repeated in other cheilostomes.
Diversity and taxonomy of intertidal Bryozoa (Cheilostomata) at Akkeshi Bay, Hokkaido, Japan
TLDR
The overall species richness of intertidal cheilostomes was two‐thirds that documented intertidally in a comparable study at Kodiak, Alaska, a locality 15° higher in latitude, and the lower richness at Akkeshi to differences in the nearshore marine environment between the two localities is attributed.
