One pelvic limb skeleton of the Lumholtz Tree-Kangaroo (Dendrolagus lumholtzii) was used in this study. Bones were prepared from the cadaver, morphologically described and the dimensions of each bone were measured. Moreover, plane X-ray images were done for the Os coxae, femur, tibia and fibula and the femur was chosen to estimate the cortical thickness index (CTI) and canal flare index (CFT). The results cleared the presence of the epipubic bones, seven tarsal bones and absence of the patella. Between the tibia and fibula there are two interosseous spaces and that the digits II, III are the smallest, while the digit IV is the largest.
