The Cadeado Higths are located in north-central Paraná, between the towns of Mauá da Serra e Ortigueiras, where permian rocks of the Rio do Rasto formation crop out. Between 2007 and 2010, in the context of research projects funded by the Brazilian agencies CNPq and FAPESP, the PaloLab conducted field work in that area and collected fossils include sharks, bone-fishes, and temnospondyls.
