Locality 36 (Beal, 1948) - Salada Fm, Loreto, Mexico (Pliocene of Mexico)

Also known as Loc. 36

Where: Baja California Sur, Mexico (26.0° N, 111.3° W: paleocoordinates 25.8° N, 110.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Salada Formation, Pliocene (5.3 - 2.6 Ma)

• From the "Salada beds"; Gardner regarded these as "Pliocene in age". A thick section of the formation, perhaps 2000-3000 ft occurs north of Loreto in a synclinal basin, and in places the beds are highly folded and rest unconformably upon older Comondu rocks. Posssibly outcrops described as Salada Fm are not all the same age, yet most appear to be Pliocene.

• bed-level stratigraphic resolution

Environment/lithology: marine; unlithified, coarse-grained, shelly/skeletal, brown, gray, yellow sandstone

• Siliciclastic facies, probably shallow water as these overly non-marine facies, but no environmental information is reported. Occurs in a synclinal basin, and in places the beds are highly folded and rest unconformably upon older Comondu rocks.
• Consist mainly of rather coarse, fossiliferous, dirty sandstones, with a few interbedded shales and conglomerates. The beds are gray, yellowish or brown. The base of this formation is composed of gravels, uncemented and apparently of terrestrial origin, which grade into well-bedded fossiliferous sandstones

Size class: macrofossils

Collection methods: quarrying,

• Stated that fossils were collected. No repositories reported. Identified by J.A. Gardner
