Algae from the Lower Palaeozoic strata of North Greenland

The present report gives an overview of algae which have been recorded in the Lower Palaeozoic strata of North Greenland and draws attention to their palaeobiological and palaeogeographic significance by correlation with their Recent relatives.

The algae are only well preserved in carbonate rocks which have been examined in thin section. The following have been recorded: Ranalcis, Gordonophyton, Wetheredella , Girvanella, Obruchevella, Sphaerocodium, Hyella, Gloeocapsa, Pleurocopsa, Solenoporaceae, Palaeoporella, Dimorphosiphon, Dasycladaceae.

Most of these are regarded as benthic shallow-water organisms and are typical indicators of a subtropical to tropical climate at the time of deposition. typical indicators of a subtropical to tropical climate at the time of depositio
