ABSTRACT:The Late Paleozoic Ice Age is recorded in the Paraná Basin as glacial deposits, deformational features and ice-related erosional landforms of the Itararé Group. Erosional landforms are often employed to build paleogeographic models that depict the location of ice masses and paleo ice-flow directions. This paper provides a review of the literature and new data on micro-to meso-scale ice-related, erosional landforms of the Paraná Basin. Examined landforms can be placed into four broad categories based on their mode of origin. Subglacial landforms on rigid substrates occur on the Precambrian basement or on older units in the Paraná Basin. They include streamlined landforms and striated pavements formed by abrasion and/or plucking beneath advancing glaciers. Subglacial landforms on soft beds are intraformational surfaces generated by erosion and deformation of unconsolidated deposits when overridden by glaciers. Ice-keel scour marks are soft-sediment striated/grooved landforms developed by the scouring of free-floating ice masses on underlying sediments. Striated clast pavements are horizons containing aligned clasts that are abraded subglacially due to the advance of glaciers on unconsolidated deposits. Only those erosional landforms formed subglacially can be used as reliable paleo ice-flow indicators. Based on these data, the paleogeography of the Paraná Basin during the Late Paleozoic Ice Age fits into a model of several glacial lobes derived from topographically-controlled ice spreading centers located around the basin instead of a single continental ice sheet. KEYWORDS:Late Paleozoic Ice Age; Itararé Group; glacial erosion; paleogeography. RESUMO: A Era Glacial Neopaleozoica está registrada na Bacia do Paraná através da sucessão sedimentar do Grupo Itararé e unidades correlatas, bem como por feições glaciotectônicas e formas de leito erosivas relacionadas à ação do gelo. Formas de leito erosivas são comumente utilizadas em análises paleogeográficas visando evidenciar o sentido de fluxo de geleiras e localizar antigos centros irradiadores de gelo. Neste trabalho é apresentada uma revisão da literatura e novos dados sobre formas de leito erosivas de micro a mesoescala
