| Taylor P.D. (2008) Bryozoans from the Middle Jurassic of Balin, Poland: a revision of material described by A.E. Reuss (1867) // Annalen des Naturhistorischen Museums in Wien, Serie A. Bd.110. P.17-54.

In 1867 A.E. Reuss described 19 species of cyclostome bryozoans from the Middle Jurassic (Upper Bathonian-Lower Callovian) of Balin, between Katowice and Krakow in southern Poland. Eight of these species were considered to be new. This paper revises the Balin bryozoan fauna based on the type material of Reuss and other specimens in the collections of the Natural History Museum, Vienna. A total of 23 species are recognizable in this collection, making it among the most diverse of Jurassic bryozoan faunas known. The four Reuss species (Hyporosopora tenera, Mesenteripora? conferta, Mesonopora concatenata, Theonoa minuta) regarded as senior synonyms are redescribed in full, while the nomenclature of the remaining species is updated. Lectotypes are chosen for Berenicea insignis Reuss, 1867, Diastopora conferta Reuss, 1867, und Pavotubigera minuta Reuss, 1867. Emphasis is placed on the morphology of the gonozooids, which were surprisingly neglected by Reuss (1867), to distinguish between closely similar species, as well as the potential taxonomic value of pseudopore shape as revealed using SEM. Many of the species present at Balin occur in the Bathonian of Normandy.
