|M. S. De la Fuente et al. 2017||Rionegrochelys caldieroi can be diagnosed as a panchelid pleurodire by the suturing of the pelvic girdle to the shell, the presence of a cervical scute, only one suprapygal bone, and vertebral scutes that are narrower than the pleural scutes. It shares with South American panchelids and Chelodina: vertebral 1 wider than vertebral 2 and axillary buttresses parallel or adjacent to costal rib 1.|
