Abstract
Plant megafossils resembling Cooksonia caledonica Lang are described f rom the Kirusillas Formation in southern Bolivia. Faunal and lithologi cal evidence together with field relationships advocate a late Siluria n (Ludlow) age. Palaeocontinental reconstructions suggest that the pla nts grew on the western edge of Gondwana at 50-60 degrees S and indica te that Cooksonia had spread to higher latitudes soon after its appear ance in the Wenlock.
