Ichnology of deglaciation deposits from the Upper Carboniferous Rio don Sul Formation (Itarare Group, Parana Basin) at central-east Santan Catarina State (southern Brazil)

摘要

Trace fossil assemblages dominated by arthropod trackways are common in sediments deposited during the Late Paleozoic Ice Age. Ichnofaunas preserved in glacially-influenced sedimentary successions were previously reported from Parana Basin in southern Brazil. The ichnofauna of the Rio do Sul Formation preserved in the rhythmites exposed in Trombudo Central quarries (Santa Catarina State, southern Brazil) is revised in this paper.
