Article
This short account is an invited contribution to the Zootaxa special volume ‘Twenty years of Zootaxa.’ Zootaxa was first published on 28 May 2001. Between this date and December 2020, 116 papers were published in Zootaxa that mention Bryozoa, comprising mostly descriptions of new species and higher taxa, but also including molecular sequencing (e.g...
Article
The number of species that exist on Earth has been an intriguing question in ecology and evolution. For marine species, previous works have analysed trends in the discovery of extant species, without comparison to the fossil record. Here, we compared the rate of description between extant and fossil species of the same group of marine invertebrates...

Conference Paper
Full-text available
New information is presented for a unique bryozoan biogenic reef system in Western Port, Victoria, Australia. A multispecies assemblage of bryozoans form biogenic mounds on unconsolidated sediment in 5-8 m water depth in an area with strong tidal currents and high turbidity. The dominant bryozoan growth form on the Western Port reefs is a rigid, fo...

Article
This paper is an invited contribution to the Zootaxa series ‘Animal biodiversity: An outline of higher-level classification and survey of taxonomic richness.’ (Zhang 2011). This series pertains to living biodiversity and the species numbers given here are more or less derived from the World Register of Marine Species (WoRMS), for which the two auth...
Article
Full-text available
Background: The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be disco...
Article
Full-text available
The anatomical structure of internal sacs for embryonic incubation was studied using SEM and light microscopy in three cheilostome bryozoans-Nematoflustra flagellata (Waters,1904), Gontarella sp., and Biflustra perfragilis MacGillivray, 1881. In all these species the brood sac is located in the distal half of the maternal (egg-producing) autozooid,...
Article
The cheilostome family Exechonellidae Harmer, 1957 is widely distributed in time and space. The genus Exechonella Duvergier, 1924 has a pan-tropical to subtropical distribution from the Eocene to the Recent and is represented by several Australian species from the Tertiary of Victoria and the Recent of the southern and eastern coasts. Some species...

Examination of samples of bryozoans from the south- eastern slope sediments of Australia ("Franklin" SLOPE Stations 6, 7), has revealed the presence of many specimens of several genera with species which have minute, rooted colony forms. Among these are new species of the genera Batopora Reuss (B. problematica) and Lacrimula Cook (L. affinis). The...
Article
The genus Adeona is a characteristic and common part of the Australian shelf fauna, extending to the tropical Indo-West Pacific. The genus first appears in the fossil record of the Miocene of south-eastern Australia. Zooid dimorphism has been recognised initially from subtle differences in the external appearance, which have not been described prev...
Article
The family Conescharellinidae Levinsen is defined and is regarded as comprising seven cheilostome genera (Conescharellina, Bipora, Trochosodon, Flabellopora, Zeuglopora, Crucescharellina and Ptoboroa). The astogeny of colonies, that consists of frontally budded zooids with "reversed" orientation, is briefly described and compared between genera. Th...

The broad-scale distribution of fossils within Victoria is controlled by general global patterns in the biological evolution of life on Earth, the local development and environmental evolution of habitats, and the occurrence of geological processes conducive to the preservation of fossil floras and faunas. Early Palaeozoic fossils are mostly marine...
Article
Members of the bryozoan family Petraliellidae share the capacity to develop basal rhizoids, which anchor the unilaminar, semi-repent parts of the colonies above the substratum, and enable them to overgrow other, competing sessile forms. Little is known of the larval behaviour and settlement, or the early astogeny of species. Ancestrulate colonies o...
Article
A new family of Cheilostomata, the Calescharidae, is introduced for the genusCaleschara MacGillivray and its Recent Australian typespecies, C. denticulata(MacGillivray), which isredefined from type and other material. The Australian Tertiary genusTretosina Canu & Bassler and its type species,T. arcifera Canu & Bassler, are closely related,and are a...

Recent sediment samples recovered from the mid-latitude South West Shelf (SWS) of Western Australia (23° - 32°S) by a scientific team aboard the RV Franklin have produced large numbers of free-living, lunulitiform bryozoans. Among these are three undescribed species, Otionellina boneae sp. nov., Selenaria kayae sp. nov., and Selenaria meganae sp. n...

Bock, P.E. and Cook, P.L., 2001. Revision of Tertiary species of Anaskopora Wass (Bryozoa: Cribrimorpha). Memoirs of Museum Victoria 58(2):179–189. The subgenus Anaskopora Wass, 1975 is raised to generic rank, separated from the genus Corbulipora, and redefined. The type species, Cribrilina elevata MacGillivray, 1895, is a Ter-tiary fossil from Vic...
Article
The abundant fossil record of well-preserved Bryozoa in samples from the Tertiary of Victoria and South Australia includes some ‘first fossil finds’ which are recorded here. Several are of species known from the Recent of the Australian or Indo-West-Pacific regions, but some represent genera with a much wider temporal and geographical range. Of the...

Bock, P.E. and Cook, P.L., 2001. Revision of the multiphased genus Corbulipora MacGillivray (Bryozoa: Cribrimorpha). Memoirs of Museum Victoria 58(2): 191-213. Corbulipora MacGillivray is redefined to include only species which occur in successive growth phases. The fossil type species, Corbulipora ornata MacGillivray, occurs in an encrusting ances...
Article
Until recently, species of the deep-water ascophoran genus Siphonicytara have been recorded from only two areas, nearly 10,000 km apart. Three species were known from the East Indies and one from the southwest Indian Ocean. A hitherto unrecognized species is now known from the southern-most Philippine region, and six new species have recently been...
Article
Bryozoans are an important part of the benthic marine fauna in a wide variety of modern environments and are found in rock forming abundance in a number of settings throughout much of the Phanerozoic. Bryozoologists and nonspecialists have grouped taxa into colonial growth forms (e.g., erect fenestrates or encrusting sheets), both to simplify analy...
Article
Full-text available
Pachystomaria parvipuncta MacGillivray is redescribed for the first time since its original introduction, from additional material from the Victorian Tertiary. Colonies are inferred to have been attached by rhizoids. The probable systematic relationships of Pachystomaria are briefly discussed.
Article
The genus Chasmazoon is introduced for Cellepora abdita MacGillivray (1895) from the Tertiary of Victoria. Chasmazoon abditum has colonies capable of both an encrusting and free-living mode of growth, and the latter were probably anchored by basal rhizoids. The large, simple orifices and striated, peristomial ovicells of C. abditum are distinctive,...

The bryozoan genus Catenariopsis was introduced for a single zooid of C. morningtoniensis Maplestone 1899, from the Tertiary of Victoria; subsequent material has been scanty and reported only once. The genus has been classified with the ascophoran family Catenicellidae and the anascan family Alysidiidae. Examination of relatively well preserved add...
Article
Examination of specimens of Aulopocella tubulifera Maplestone, and of A dimorpha sp. nov., from the Tertiary of Victoria, has revealed that the colonies are constructed by 'reversed frontal budding', an astogeny typical of the family Lekythoporidae. Previously, only Lekythopora hystrix MacGillivray had been recognised as a fossil, as well as a Rece...
Article
Two new genera of the bryozoan family Calloporidae are described from New Zealand. The first, Leptinatella, is introduced for L. gordoni n. sp., specimens of which have been referred in the past to Watersia militaris (Waters) but are distinct from this species, which is a phase of the cribrimorph Corbulipora tubulifera (Hincks). The second genus, B...
