Ludlow and Pridoli (Upper Silurian) graptolite biostratigraphy of the central Arctic Islands: a preliminary report
A fauna, comprising slightly more than 30 species of Upper Silurian graptolites, has been recognized from the Arctic Islands. The following preliminary biostratigraphic biozones are recognizable: Lobograptus progenitor, Saetograptus fritschi linearis, and Bohemograptus bohemicus tenuis zones of Ludl...
