Original description: ibid.

Wiedenmayer (1924, p. 511) includes the lenticular limestones at Cerro Campana (which lies about 7 kilometers north-northwest of El Mene de Acosta, Eastern Falcón) into his Curamichate or Guayavalserie, which is based on erroneous correlation. The Cerro Campana limestone is an algalorbitoidal reef limestone containing innumerable specimens of Lepidocyclina. Gorter and Van der Vlerk (1932) and Gravell (1933) described the larger foraminifera from the Cerro Campana limestone to which Senn (1935, p. 68, 69) assigns an uppermost Eocene age.

Senn (1935, p. 68, 69) introduced the name Cerro Campana-Schichten which consists of 200 to 400 meters a sandy-clayey formation, containing a small Lithothamnium limestone reef with abundant larger foraminifera (Gorter and Van der Vlerk, 1932; Gravell, 1933). It is recommended to drop Senn's ill-defined Cerro Campana-Schichten as a valid stratigraphc term and retain Cerro Campana limestone for the upper Eocene limestone reef at Cerro Campana. Senn's Cerro Campana-Schichten are largely synonymous with the Guacharaca formation which, according to Renz (1948, p. 8) includes in its lower part at Guacharaca some orbitoidal limestone lenticles of the Cerro Campana limestone type.

Liddle (1946, p. 299, 357, 370, 372, 380, 381) uses interchangeably the names Cerro Campana formation and beds, and mentions that they overlie the Cerro Misión formation.
