Abstract

Charophytes are non-marine green algae living on the bottom of ancient andRecent lakes and in other non-marine environments. The fossil record of Cretaceous Charophyta considered in this paper includes 56 organ-species, andis the best known of the ancient assemblages in South America. The stratigraphic distribution of these species is outlined using world-wide chronostratigraphic units. Three correlated biogeographic patterns are discussed in the framework of the main geological changes. Early Cretaceous records indicate a high rate of endemism. In the Aptian some barriers of isolation seemto have been broken or bypassed. Despite many cases of widely distributed species, two separate Late Cretaceous biogeographic provinces are recognized: the Andean Province and the South Atlantic Province. (C) 2000 Academic Press.
