In the northeastern zone of the department of Boyacá, in the locality of Socha, areas with a high fossiliferous potential of microvertebrates and vertebrates, as fish, crocodiles and, particularly, turtles, of middle and upper Paleocene age of the Arcillolitas de Socha Formation have been identified. Along this sector, detailed stratigraphic sections and geological profileswere elaborated, which together with lithostratigraphic and biostratigraphic techniques, allowed us to differentiate the formation into three members and to identify the prospecting areas of two fossiliferous levels of interest, as well as a group of key sandstones located in the intermediate levels. The paleoenvironments identified for the formation indicate a lagoonal, marshy, paludal, and deltaic sedimentation for the sandstones, generally sedimented in a continental depositional environment. All the information obtained could be applied for the eventual location of fossils in prospecting and exploration in subsequent research, as wellas highlighting the imperative need to strengthen local laws in favor of the protection and preservation of these paleontological deposits in the region.
