Skeletal diagrams of Patagopelta cristata as a parankylosaur, showing known osteoderms (top) and appendicular/axial skeleton (bottom). Osteoderms are placed in approximate life position as proposed by Riguetti et al. 2022. Scale bar=50 cm. Illustrated osteoderms include the holotype specimen, MPCA-SM-78 (a cervical half-ring element), paratype specimens—710 (a right quadratojugal boss; mirrored), 700b (an osteoderm associated with the vertebra 700a), 711 and 712 (cervical half-ring osteoderms), 41a, 41b, 42a (mirrored), 715, 720, and 721 (postcervical osteoderms)—and referred material, MACN-PV-RN 1149 (five osteoderms). Illustrated non-osteoderm bones include MPCA-SM-700a (partial cervical neural arch), 68, 69, and 70 (dorsal vertebrae), 703 (synsacral compound elements), 71, 72, 73, and 708 (caudal vertebrae), 1 (complete right femur), and 709 (distal ~1/3 of left femur). Several bones were not illustrated as they have not been scientifically figured or would decrease diagram readability. These include MPCA-SM-713 and 714 (cervical half-ring osteoderms) 42b, 43, 74, 75, 76, 716, 717, 718, 719, 722, 723, 724, and 725 (postcervical osteoderms), 77 (a tooth), 701 and 702 (dorsal vertebrae), 704 (a synsacral compound element belonging to a smaller individual), and 705, 706, and 707 (caudal vertebrae).
