“…In addition to the limited collection effort, small bryozoan colonies tended to be overlooked in the field and inventories are therefore largely incomplete. Consequently, taxonomic studies of bryozoan faunas from the early Miocene are generally limited not only for the Caribbean/Gulf of Mexico region (e.g., Sandberg, 1962; Cheetham et al, 1999, 2007; Herrera-Cubilla and Jackson, 2014; Di Martino et al, 2017), the western Atlantic (e.g., Zágoršek et al, 2014; Ramalho et al, 2015, 2017, 2019), or the Indo-Pacific (e.g., Li, 1990; Guha and Gopikrishna, 2005, 2007; Di Martino and Taylor, 2014, 2015), but also for the more thoroughly investigated Paratethys/Mediterranean Sea (e.g., Duvergier, 1920; Buge, 1973; Nikulina and Taylor, 2010; Vávra, 2012; Di Martino and Taylor, 2017).…”

This is the first of two comprehensive taxonomic works on the early Miocene (ca. 23–20 Ma) bryozoan fauna associated with coral reefs from the Siamaná Formation, in the remote region of Cocinetas Basin in the La Guajira Peninsula, northern Colombia, southern Caribbean. Fifteen bryozoan species in 11 families are described, comprising two cyclostomes and 13 cheilostomes. Two cheilostome genera and seven species are new: Antropora guajirensis n. sp., Calpensia caribensis n. sp., Atoichos magnus n. gen. n. sp., Gymnophorella hadra n. gen. n. sp., Cribrilaria multicostata n. sp., Cribrilaria nixor n. sp., and Figularia bragai n. sp. Eight species are identified only at genus level and remain in open nomenclature. Of the species found, 27% have erect colonies and 73% encrusting colonies. Both types contributed to the reef framework and produced sediment. The observed bryozoan diversity was higher in the barrier reefs than in the lagoonal patch reefs.

“…The calcareous structures produced by most bryozoans generate rich fossil records, thus being also useful as palaeoindicators (e.g. Smith, 1995;Taylor, 2005;Berning, 2007;Ramalho et al, 2017;Bastos et al, 2018). Furthermore, bryozoans are an important group of fouling organisms encrusting ship hulls, pipes, cables, buoys, nets and almost any submerged hard substrate; fouling causes financial loss and is a potential mechanism of invasive species dispersal (Gordon et al, 2006;Bressy & Lejars, 2014).…”

Knowledge of the marine bryozoan fauna of Uruguay is mostly based on scattered records found in local faunistic surveys and the taxonomic results of two oceanographic cruises to the Southwest Atlantic, but a comprehensive study has not yet been published for this area. This paper aims to compile an updated checklist, bringing together all the published information about the Uruguayan bryozoan fauna. Of the 73 recorded taxa, 30 (41%) are known only from deep waters off the Río de la Plata. Even considering undetermined species, these results show the high degree of endemism as it was already shown for several other benthic groups such as Bivalvia, Ascidiacea and Pycnogonida. The absence of local taxonomists on bryozoans has resulted in the unprecedented situation that the deep-sea bryozoan fauna of Uruguay is better known than the coastal and shelf representatives of the phylum. The main conclusion of this faunal compilation is that efforts should be made to coordinate the gathering and taxonomic study of shallow and shelf bryozoan collections to bridge the present knowledge gap about the biodiversity of this important group of marine benthic invertebrates.
