The dasycladacean nature of Late Paleozoic palaeoberesellid algae

Stanisław Skompski


The exceptionally well preserved moulds of problematic microfosiIs from the tribe Palaeoberesellae MAMET & ROUX 1974, were found in the Lower Carboniferous limestones in the Lublin Coal Basin and in the Sudetes in Poland. The morphology of moulds allowed to state a dasycladacean affinity of the group, which previously was assigned not only to the calcateous algae, but also to the foraminifers and even to the sponges. The recognition of the dasycladacean nature of the tribe Palaeobereselleae evidences precisely their role as a palaeoenvironmental indicator, what is exemplified by the Waulsortian buildups in Western Europe
