Stratigraphy

Formation:	Los Alamitos
Stratigraphic resolution:	group of beds
Stratigraphy comments: middle section of formation includes vertebrate fossils distributed over about 30 meters of section Mammals: Middle section of Los Alamitos Formation - green-coloured bed just below the concretionary top of the Cerrito del Mamifero, Alamitian provincial age (Campanian sensu lato)

Lithology and environment

Primary lithology:	planar lamination,bioturbation,concretionary,yellow siltstone
Secondary lithology:	bioturbation,intraclastic sandstone
Includes fossils?	Y
Includes fossils?	Y
Lithology description: "Pelitic facies: includes dominant massive, laminated or rippled (rare) siltstones and claystones, with yellowish (lower part of the sequences) to reddish, orange, brown and purple hues (upper part), and massive sandstones. This rocks show typical paquidermis solution pattern which allow its recognition in outcrops. The non-calcareous pelites contains (lower half) almost all the vertebrate remains"
Environment:	lacustrine - large
Geology comments: dominant environment lacustrine, more brackish than fresh (clay flocculation in pelites). waters were oxygenated; lake permanent and shallow. The paleoenvironment according to Andreis (1987; and personnal communication) is that of a lacustrine environment mixed with shallow marine sediments, as indicated by the presnce of glauconite in some levels of the sequence.
