Left foot of a tyrannosauroid dinosaur in anterior (extensor, dorsal) view, showing the arctometatarsalian condition. The dorsal surface of the missing proximal part of metatarsal III is graphically restored. Its most proximal part would have been concealed by the most proximal portions of metacarpal II and IV which are in contact to one another. Scale is inferred from size of business cards in the original image (see below).
