The spirit dell'armadillo

A group of researchers describe the rest oldest known up to a kind of armadillo, the discovery was made in the material found 30 years ago during an expedition to Bolivia and deposited in the natural science museum in Paris.
The evolutionary history of the modern order of xenartri is still poorly understood, according to the analysis of the DNA of the modern species-specific subfamily of Tolypeutinae, which was attributed to the new fossil species, was separated from other families about 26 million years ago and to date the fossils known reached a maximum age of 12 to 14 million years.
call missing 15 million years of evolutionary history of gruppo, una sorta di linea fantasma che
collegava i rari fossili all´ultimo comune antenato degli armadilli rilevato dalla genetica. Questa mistero ha anche suggerito il nome per il nuovo genere e specie che con 26 milioni di anni raggiunge l´eta sostenuta dai dati genetici - Kuntinaru , che nel dialetto di Aymara, una lingua nativa delle Ande boliviani, significa " Spirito ".
