GINKGOPHYTES FROM THE UPPER PERMIAN OF THE BLETTERBACH GORGE (NORTHERN ITALY)
Fossil evidence of late Palaeozoic ginkgophytes is rare; Palaeozoic floras in which ginkgophytes are abundant or represent a predominant element have not previously been described. The late Permian (Lopingian) flora from the Gröden/Val Gardena Sandstone of the Bletterbach gorge in the Dolomites (northern Italy) contains an unusually large proportion of
