Resumen:
Fernandez-Pacella, L., Zacarías, G., di Pasquo, M. 2019. Palaeoenvironment associated with giant tortoises of Toropí/Yupoí Formation (late Pleistocene 50-28 ka), Corrientes province, Argentina. Vertebrate faunas of the Mesopotamian region in Argentina provided palaeoclimatic and palaeoenvironmentalinformation from the Pleistocene. Samples collected into a carapace of the turtle Chelonoidis lutzae and associatedsediments obtained from the Toropí/Yupoí Formation (Arroyo Toropí, Bella Vista) palynologically studied for the firsttime. 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., Agaricussp.). Palaeoecologic requirements of these botanical groups indicate the predominance of herbaceouspalaeocommunities associated with arboreal or shrubby elements and fresh waters bodies. They characterizeddynamic scenarios typical of ecotonal zones under arid/semi-arid and humid warm seasonal climates during the LatePleistocene (Last Maximum Glacial) in the Mesopotamian region
