The first record of Cooksonia from South Americain Silurian rocks of Bolivia

  • E. Morel (a1), D. Edwards (a2) and M. Iñigez Rodriguez (a3)


Plant megafossils resembling Cooksonia caledonica Lang aredescribed from the Kirusillas Formation in southern Bolivia.Faunal and lithological evidence together with field relation-ships advocate a late Silurian (Ludlow) age. Palaeocontinentalreconstructions suggest that the plants grew on the western edgeof Gondwana at 50–60° S and indicate that Cooksonia hadspread to higher latitudes soon after its appearance in the Wenlock.
