C. Wiedenmayer (1924, p. 510-512) created the name Capadareserie for a rather complex sequence of Miocene-Plíocene rocks throughout Eastern Falcón. Most of these rocks are erroneously correlated and are now known and defined under different stratigraphic names. Wiedenmayer's Capadareserie also includes the Capadare limestone with type locality at Cerro Capadare, District of Acosta, Eastern Falcón. lt is only for this unit that the name Capadare is retained.

The Capadare limestone was originally described by Wiedenmayer (1924) as a light-colored Lithothamnium limestone which, according to Senn (1935, p, 81, 83) is also called Clypeasterkalk (Capadare-Kalk), with a thickness of about 135 meters and containing Amphistegina sp., Sorites sp., Bolivina sp., mollusks and echinoids (Clypeaster and Scutellidae). The important genus Miogypsina is absent.

Senn considers the age of the Capadare limestone, which is interbedded in the upper part of his A1a Agua Salada zone, as middle Miocene.

In the nomenclature of H. H. Renz (1948, p. 24, 66, 69) the Capadare limestone lies within the Huso clay member of the Pozón formation (Agua Salada Group), in the upper part of the Robulus senni zone (Lucian stage), for which a middle Miocene (Helvetian) age is indicated.

Liddle introduces the name Capadare formation (1928, p. 343-345) which includes the Capadare limestone (also referred to as Jacura and Guaidima limestone) as defined here, as well as other stratigraphic units that are now known to occupy different stratigraphic levels. Liddle (1946) refers in many places to the Capadare limestone but omits a formal discussion of the unit.
