Lithology description: 3) Reddish-brown, medium to fine sandstones, thick in the upper part and slightly conglomeratic. The calcareous cementation is only evident in the upper sector, whereas the rest is friable. In the lower third, of pink color, some small yellowish banks with gastropod remains are intercalated. It is possible to find bony remains in this entire assembly. Irregular chocolate-colored lenses of muddy-clayey texture are also intercalated. Total thickness: 12.5 m. (Translated from Spanish by M.
