Abstract | The bryozoan faunas from a few important localities of the early Miocene of the Austrian part of the Central Paratethys are briefly described. All bryozoan faunas belong to the late Eggenburgian or early Ottnangian except for two localities yielding only a few rather poor fragments of bryozoans. Faunal migrations from the Western Mediterranean via the Rhône Basin into the Alpine Foredeep and the Central Paratethys best explain the geographic distribution of a number of bryozoan genera in the faunas of the Eggenburgian. A short climatic deterioration during this time-span may explain the occurrence of bryozoan-rich strata at this time characterized by extended temperate-water sedimentation. This climatic event could also explain why some genera are either extremely rare (e.g. Steginoporella) or even completely absent. |
