CUPUL-MAGANA, Fabio Germán y MOUNTJOY, Joseph B.. Trachemys ornata (Gray, 1831) (Testudines: Emydidae) in an archaeological site in western Mexico. Acta Zool. Mex [online]. 2012, vol.28, n.1, pp.222-226. ISSN 0065-1737.
Carapacial and plastral bones from "El Pantano" archaeological site in Mascota Valley, Jalisco, Mexico have been identified as Trachemys ornata (Ornate Slider). The tortoise was placed as an offering over the burial of an infant and a child. Since the burials at this site have been radiocarbon-dated to approximately 800 B.C. this is an ancient documented cultural use of T. ornata in Mesoamerican archaeology.
