A total of 31 yellow armadillos, Euphractus sexcinctus, were captured in the Pantanal of Nhecolândia, Brazil, between October 2006 and October 2007. The individuals were anesthetized and measured. This study presents data about body mass, number of moveable bands, head length and width, head and body length, tail length and circumference, chest circumference, ear length and width, forefoot and hindfoot length, and penis length. Morphometric averages of yellow armadillos were compared with other values available in the scientific literature. The data provided in this study will be useful for further comparative studies.
