This unit first referred to and described by Liddle (1928, p. 267-268). According to him, the term "Boca de Don Diego" applies to a restricted outcropping of strata along the Caribbean Sea between Boca de Ventura and Boca de Don Diego. The narrow zone of outcrop is surrounded by younger deposits. The exposed 1800-foot section includes bluish and grayish-black, gypsiferous, arenaceous, lignitic, and pyritic shales, interbedded with massive, brownish gray, locally petroliferous sandstones. Some lignitic coal beds occur in the higher part of the exposed section. These coal beds may belong to the Cerro Pelado or even the Socorro formations.

The exact equivalents of the Boca de Don Diego beds in the standard stratigraphic section for eastern Falcón are not fully agreed upon, but are belived to range through the Agua Clara, Cerro Pelado, Socorro, Caujarao and even the La Vela, according to Liddle (1946, p. 431).

The term "Boca de Don Diego" is obsolete in a stratigraphic sense.
