Dinosaur remains are among the fossils that have been recovered from the formation.[1] The formation comprises friable, micaceous, grayish-red sandstones with quartz pebbles furrowed with small carbonate veins. In the base of this layer the remains of a titanosaurid dinosaur were discovered. Above the layer with bones appears a lens of thick, greenish-gray, calcareous, very hard sandstone with pebbles and gravel. The bones were covered by a "halo" of the same rock but of greenish or grayish color, especially visible because the normal sediment is red. The bed thickness is {{convert|1.5|m|ft}}.[2] Vertebrate paleofauna
