UCMP Locality V4534 Type locality: Motley gray to red clay between conglomerate members about 180 meters east of quebrada Tatacoa (= Rio Tatacoa), 1/2 Kilometrer downstreamfrom deep canyons through upper conglomerate members. This locality coordinates were estimated using the map of localities from Fields (1959) and Stirton (1951), which locates the stratigraphical sections on the map, and the Guerrero map (1997) was used to determine with greater precision the coordinates.

In 1979 field season, the upper premolars and the molars of Stirtonia tatacoensis were found in the Upper Miocene La Venta badland of Colombia. (...) The specimens were collected on eroded surface of clay of the Honda Formation within a single spot (50cm2) The specimens were collected on eroded surface of clay of the Honda Formation within a single spot (50cm2) The edentulous right maxillary ramus has three alveoli for premolars and broken roots of the premolars are enclosed in all the alveoli. The breaks of the roots are flesh. The roots of the isolated P, P3 and P4 discovered are broken but the breaks are also flesh. These premolars and maxillary fragment were carefully reconstructed and all these broken pieces beautifully fit together. This means that the isolated P2. P3 and P4, and the maxillary fragment belong to a single individual. The M1 is exactly identical morphologically to the corresponding tooth of the holotype of Stirtonia tatacoensis. The size of the M’ and M2 is almost the same as that of the M1, and the width of the P-’ is also the same as that of the ML. All the teeth discovered are almost unworn and this fact means that they show the same degree of wear of teeth. Because of these evidences together with the fact that all the specimens at hand were found in a single spot, it is safely concluded that all the specimens belong to a single individual so that the upper teeth collected are identified as Stirtonia tatacoensis.
