Time
Period: Permian Epoch: Guadalupian
Stage: Wordian - Capitanian 10 m.y. bin: Permian 4
Key time interval: Wordian - Capitanian
Age range of interval: 266.9 - 259.51 m.y. ago
Stratigraphy
Geological group:Passa Dois Formation:Rio do Rasto Member:Morro Pelado
Stratigraphic resolution:group of beds
Stratigraphy comments: The beds from which vertebrates come are correlated with the Tapinocephalus Assemblage Zone (Karroo) and the Isheevo Complex (Russia), which are Capitanian or Wordian to Capitanian in age (Cisneros et al. 2005, fig. 6; Tsuji & Müller, 2008, Can. J. Earth Sci. 45, fig. 2). For discussion see Cisneros et al. (2005, p. 21).
Lithology and environment
Primary lithology: claystone
Secondary lithology: conglomerate
Lithology description: "The rocks outcropping at the Posto Queimado locality belong to the Morro Pelado Member, and are characterized by a sequence of pelites, interspersed with clay lenses, sand and intraformational conglomerates." Pacheco et al. 2016
Environment:fluvial-lacustrine indet.
Geology comments: The depositional environment of the Morro Pelado Member has been interpreted as meandering fluvial to lacustrine, deltaic and aeolian (Rohn 1994), Holz et al. (2010a) suggesting alluvial conditions with coalescing flood plains, including crevasse splay deposits and inundites of occasional shallow river channels.
