 The horizontal ridge may be an autapomorphy of "P. chiniquensis", yet it has also been reported in "Procerosuchus" and "Batrachotomus".The rod-like clavicles have a tall vertical portion which connects to the front of the scapula and a shorter horizontal portion at their base which connects to the tie-shaped interclavicle.The humerus is thick and about two-thirds to three-fourths the length of the femur.
