Comparative histology and ontogenetic change in the carapace of armadillos (Mammalia: Dasypodidae) [PDF]
Zoomorphology, 2015 Among extant mammals, the presence of osteoderms is limited to armadillos (Xenarthra, Dasypodidae), being one of its distinctive features. The osteoderms are articulated to form a carapace that covers their body dorsally. In this paper we study the integumentary structures of the armadillos Chaetophractus vellerosus, Chaetophractus villosus, Euphractus
