Inhabited by shepherd families who mainly own goats and cattle, the Tatacoa is considered to be one of the largest vertebrate fossil sites of America, thanks to the evolution of its earth layers and to the conditions that have facilitated the accumulation of specimens that represent prolonged periods. Certainly, it is the most varied paleontological record for the Miocene and Pleistocene in Colombia and in the continent.
