Calcification affects the sheath of some coccoid and filamentous cyanobacteria during their
life, under suitable environmental conditions. There is probably a link between sheath …

This compendium records 139 critically assessed valid genera and 22 form-genera of
Carboniferous blue-green, green and red algae. It also includes some umbellinids, algal …

Limestone erratics in the Early Miocene glacio− marine Cape Melville Formation of King
George Island, West Antarctica, have yielded Early and Middle Cambrian small skeletal …

Abstract In the Mississippian in Western Europe, biostratigraphic zonation and correlation of
sequences has been refined using a combination of faunal and floral groups. In deep‐water …

In this study, middle to late Mississippian microfossil assemblages from the Maritimes Basin

Detailed sampling of limestones from the Mobarak Formation at the Abrendan and Abnak
measured sections in the eastern and central Alborz Mountains, northern Iran, yielded a …

Givetian, Frasnian and Famennian limestones from southern China contain microfossils
