Figure 2.

Three-dimensional rendered micro-CT images of cordyline lizards illustrating the dichotomy in defensive traits. Smaug giganteus (a), as well as members of the genera Ouroborus (b), Cordylus (c) and Karusasaurus (d) are characterized by imbricating rectangular osteoderms covering the body. In other members of the genus Smaug (e), the body is covered with well-developed disc-like osteoderms. In Ninurta (f) and Pseudocordylus (g), the trunk region is completely devoid of osteoderms or osteoderms are extremely reduced.
