<scp>Gross Anatomy of the Thoracic Limbs of Small South American Cervids</scp> ( <i>Mazama</i> spp. and <i>Subulo gouazoubira</i> )

This study describes the anatomical and morphological features of the thoracic limbs of different species of South American cervids, with functional interpretations, serving as a reference for clinical and research purposes through dissections, imaging examinations and osteotechnique. 16 thoracic limbs from eight cervids of the genera Mazama and Subulo were analysed. The general limb anatomy was similar to that described for domestic ungulates, with species specific particularities such as less robust and more delicate bones. The hand skeleton displayed rudimentary distal metacarpal bones, characterising the genera as tele metacarpal deer, which are phylogenetically typical of New World cervids. Radiographic examinations and morphological analyses allowed for the visualisation of anatomical patterns specific to South American cervids.
