Plant macrofossils studied in coprolites from small-sized, medium-sized and large mammals, dated by 14C to ca. 30.8e24 and 9 kybp, allowed to record changes in local vegetation and its relation with geomorphological units. Paleobotanical samples were determined using microhistological analysis. We found that plant associations and the vegetationegeomorphology relation were similar in the two periods analyzed. According to this study, the Monte plant formation would reflect certain stability during the analyzed period in arid central-western Argentina, although this does not imply the absence of variations in plant structure.C to ca. 30.8e24 and 9 kybp, allowed to record changes in local vegetation and its relation with geomorphological units.
