Ichnofabrics and ichnofossils from the continental deposits of the Serra da Galga Member, Marília Formation, Bauru Group (Upper Cretaceous), Uberaba, Minas Gerais, Brazil
چکیده انگلیسی
The ichnofabrics and ichnofossils from two outcrops of the Serra da Galga Member (Marília Formation, Upper Cretaceous), in the Municipality of Uberaba, Minas Gerais of Southeastern Brazil, are analyzed: the first is characterized by fluvial deposits (braided rivers) and paleosols with a set of ichnofabrics comprising rhizobioturbation, rhizohalo-Skolithos, Skolithos, Taenidium, and Skolithos-Taenidium barretti; and the second have more influence of alluvial deposition and is characterized by occurrences of crustacean (decapod) Thalassinoides-like burrows. A reassessment of the Asthenopodichnium marks in the "pseudo-coprolites" is also discussed. The Scoyenia ichnofacies is suggested as being the most representative for the sedimentary deposits of the Serra da Galga Member in Uberaba.
