Tilatá Formation
The Tilatá Formation (, N1t, Tpt) is a formation (geology), geological formation of the Bogotá savanna, Altiplano Cundiboyacense, Cordillera Oriental (Colombia), Eastern Ranges of the Colombian Andes. The formation consists of coarse to very coarse conglomerate (geology), conglomerates and sandstones. The Tilatá Formation dates to the Neogene period; Pliocene, Early to Late Pliocene epoch (Montehermosan to Uquian in the South American land mammal age, SALMA classification, from approximately 5.3 to 2.7 Ma), and has a maximum thickness of . The formation underlies the Quaternary sequence of alluvial, lacustrine and fluvial sediments of Lake Humboldt, Colombia, Lake Humboldt. Etymology The formation was first defined and named by Scheibe in 1933 after the Hacienda Tilatá in Chocontá, near the Sisga Reservoir. Hubach (1957) elevated the ''Pisos de Tilatá'' to a formation.Montoya & Reyes, 2005, p.68 Description Lithologies The Tilatá Formation consists of medium to coarse ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
