This paper provides a guide to the field trip of the 2018 edition of the Paleodays, the annual congress of the Società Paleontologica Italiana (Trento, 6–8 June 2018), dedicated to the terrestrial ecosystems of the Dolomites between the late Permian and the Middle Triassic. It is structured into three stops (Fig. 1). We will first visit two outcrops located near Tramin/Termeno, where the Permian–Triassic boundary is exposed, and in the Bletterbach Gorge, where the late Permian crops out in an extensive and spectacular succession. The third stop offers a visit to the Geological Museum of the Dolomites, in Predazzo, which allows us to discuss about carbonate platforms and the diversification of plants and tetrapods in the Middle Triassic
