Notes that red beds and reddish conglomerates in the San Pedro and other areas of Lara are part of the Cretaceous Rio Negro formation rather than the lithologically similar La Quinta formation (Triassic and Jurassic). The northeasternmost exposure of the latter is found near Carache, where approximately 150 feet of these sandstones, conglomerates, and reddish shales and siltstones are preserved in a syncline. At the Carache locality, the La Quinta beds are overlain by recent colluvial and alluvial deposits, but to the south in the Merida Andes, they are unconformably overlain by the Rio Negro formation.
