Environment/lithology: "channel"; siliciclastic sediments

• "Graded beddings of clay, siltstone, and poorly sorted sandstone. The whole thickness 40 m. The basic cycle comprises buff-grey fine-to-medium-grained, cross-bedded sandstone with conglomeratic lenses containing vertebrate remains. This gradually changes above into a subhorizontal alternation of red-buff siltstone, limestone, and fine-grained clayey sandstone. The cycle thickness is 8 m." (Tverdokhlebov et al. 2005)
