scenario and for each season: (A) summer, (B) autumn, (C) winter (austral summer), and (D) spring

Moreover the lack of typically Early Triassic fossils can be explained not only by slow recovery after
the Permian-Triassic biologic crisis (López-Gómez et al., 2005), but also by a true stratigraphic break during
the Early Triassic, i.e. Induan, and/or by climatic conditions that were unfavourable for the development of
flora and fauna during the lower Olenekian, i.e.‘desert’ environments (Bourquin et al., in press). The early
