A mid-Cretaceous (Albian–Cenomanian) shell-rubble bryozoan fauna from the Goshoura Group, Kyushu, Japan
- Environmental Science, Geography
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.
Anomia-associated bryozoans from the upper Pliocene (Piacenzian) lower Tamiami Formation of Florida, USA
- Environmental SciencePalaeontologia Electronica
Commercial mining northeast of Sarasota, SW Florida (USA), since the 1960s has exposed Plio-Pleistocene marine shell beds of the Tamiami Formation, a complex sequence of mixed carbonate and…
Mineralogy of cheilostome bryozoans across the Eocene–Oligocene boundary in Mississippi, USA
- Geology, Environmental SciencePalaeobiodiversity and Palaeoenvironments
Different cheilostome bryozoan species construct their skeletons from calcite, aragonite, or a combination of these two minerals. Calcite is the primitive biomineral in cheilostomes, but an…
Evidence for Polyphyly of the Genus Scrupocellaria (Bryozoa: Candidae) Based on a Phylogenetic Analysis of Morphological Characters
- BiologyPloS one
The bryozoan genus Scrupocellaria comprises about 80 species in the family Candidae and is redefined according to four morphological features: vibracular chamber with a curved setal groove, ooecium with a single ectooecial fenestra, two axillary vibracula, and a membranous operculum with a distinct distal rim.

METRARABDOTOS AND RELATED GENERA (BRYOZOA: CHEILOSTOMATA) IN THE LATE PALEOGENE AND NEOGENE OF TROPICAL AMERICA
- Environmental Science
A complete reanalysis of the original morphometric data is presented, incorporating the new tropical American material and comparative material of selected Metrarabdotos species from Europe and Africa in order to formalize the taxonomy of the genus.
The fauna of the Clayton Formation (Paleocene, Danian) of southern Illinois: a case of K/P survivorship and Danian recovery
- Geology, Environmental Science
Identification of 8640 specimens of bryozoan, mollusk, decapod, and vertebrate fossils from the Paleocene Clayton Formation in southern Illinois has resulted in recognition of 44 species-level taxa…
