Talenkauen santacrucensis n. gen. et sp., meaning \\\"small head\\\" in the Aonikenk Indian languageis based on a allmost complete skeleton from Maastrichtiano rocks of southwestern Patagonia, is odd in the presence of plate-like structures on both sides of the thorax, which are better interpreted as uncinate processes than dermal armor.
