ARELLANO, Francisco; QUEZADA, Lyta  and  OLAVE, Carlos. Cassidulinidae family (Protozoa: Foraminiferida) from chilean patagonic channels and fjords. Anales Instituto Patagonia (Chile) [online]. 2011, vol.39, n.2, pp. 47-65. ISSN 0718-686X.  http://dx.doi.org/10.4067/S0718-686X2011000200004.

(Protozoa: Foraminiferida). It was identifed 12 species, classifed in 4 genera. The most wide geographic distribution taxa in the channels and fjords were: Globocassidulina rossensis (50,6 % of samples), Cassidulinoides parkerianus (42,1 %) and Cassidulina laevigata (34,8 %). Mention for presence of this 12 species from their localities in Chile was carried up. It was collected 29.033 specimens and the most abundant species were: Globo-cassidulina minuta (42,2 %), Globocassidulina subglobosa (19,9 %) y Globocassidulina rossensis (16,7 %).
