| Popis | Combined study of conodonts and foraminifers through the middle Tournaisian-lower Visean in Moravia and a compilation of conodont and foraminiferal data from Palaeotethyan, Siberian and North American Realms enables worldwide correlation of Lower Carboniferous foraminiferal zonations, discussion of the interval about the Tournaisian-Visean boundary, and evaluation of the biogeography of calcareous foraminifera. Emigration-immigration events affecting foraminiferal faunas in higher latitudes correlate with eustatic and isotopic events. These are consistent with climatic forcing connected with glaciation in Gondwana. The palaeobiogeograpic pattern of foraminiferal faunas at the Godwana-Laurussia interface seems to distinguish Eastern Avalonia on the southern Laurussian shelf from Perigondwanan terranes to the south. |
