Resumen
Vertebrate faunas of the Mesopotamian region in Argentina provided palaeoclimatic and palaeoenvironmental information from the Pleistocene. Samples collected into a carapace of the turtle Chelonoidis lutzae and associated sediments obtained from the Toropí/Yupoí Formation (Arroyo Toropí, Bella Vista) palynologically studied for the first time. The palynomorph association includes angiosperms (Brassicaceae, Amaranthaceae, Poaceae, Sapotaceae, Fabaceae, Euphorbiaceae, Myrtaceae), Bryophyta, Pteridophyte (Microgramma squamulosa), chlorophytes (Pediastrum tetras, Botryococcus) and fungal spores (Dichomera, Phaeoseptoria sp., Phragmotrichum sp., Agaricus sp.). Palaeoecologic requirements of these botanical groups indicate the predominance of herbaceous palaeocommunities associated with arboreal or shrubby elements and fresh waters bodies. They characterized dynamic scenarios typical of ecotonal zones under arid/semi-arid and humid warm seasonal climates during the Late Pleistocene (Last Maximum Glacial) in the Mesopotamian region.
