Original description: ibid.

R. A. Liddle (1928, p. 234-235) first mentioned the Urama beds. In 1946, he gave to these beds the rank of a stratigraphic unit by including them in his Correlation Chart. The type locality is in the Rio Urama, a few kilometers to the north of the town of Urama, State of Carabobo. In the original publication there are two mistakes concerning the type locality: the name is written "Urania" and the locality is in the State of Yaracuy. Liddle (1946, p. 362) corrected the name "Urania" for Urama, but erroneously located the town in the State of Cojedes. There is no doubt about the town of Urama being the one in the State of Carabobo, since Kehrer (1937, p. 66-67), as quoted by Liddle (1946, p. 362), states: "to the west of Puerto Cabello, between El Palito and Urama, slightly metamorphosed sandstones and shales of the Misoa-Trujillo type of the Eocene were found". Besides these rocks and according to Bremmen and Rohwer, fide Liddle (1928, p. 234-237), the Urama beds are mainly characterized by grayish hard limestones from thin, outcropping beds, which contain a great abundance of Orthophragmina sp., that Liddle (1928, p. 235) considered of probable Eocene (Jacksonian) age and equivalent, in part, to his Soldado formation (note that the name Soldado used by Liddle for the upper Eocene, is an homonym of the name Soldado of Maury (1925), which is a Paleocene formation).

According to Liddle's Correlation Chart (1946) the Urama beds are also equivalent to the Rio San Pedro and Rio Caus formations.

The name Urama beds is obsolete.
