Summary In order to evaluate the hind limbs of caviomorph rodents a descriptive analysis of the C uniculus paca ( L innaeus, 1766) and H ydrochoerus hydrochaeris ( L innaeus, 1766) was performed using anatomical specimens, radiography, computed tomography ( CT ) and full‐coloured prototype models to generate bone anatomy data. The appendicular skeleton of the two largest rodents of N eotropical A merica was compared with the previously reported anatomical features of R attus norvegicus ( B erkenhout, 1769) and domestic C avia porcellus ( L innaeus, 1758). The structures were analyzed macroscopically and particular findings of each species reported. Features including the presence of articular fibular projection and lunulae were observed in the stifle joint of all rodents. Imaging aided in anatomical description and, specifically in the identification of bone structures in C uniculus paca and H ydrochoerus hydrochaeris . The imaging findings were correlated with the anatomical structures observed. The data may be used in future studies comparing these animals to other rodents and mammalian species.
