I received Temaiken's answer: according to the park they house pichi armadillos, and the specie can be seen in the burrowing animals' exhibits.
"Refugio Faunístico Luan" in Neuquén, Argentina might have also that specie, the zoo tends to receive injured animals and wild animals that used to be pets. The zoo has a great collection of native species, however I could not contact the zoo.
Oh boy!! I was definitely planning on visiting Temaiken anyways!! Can't wait!!
