Phalanx bone and far phalanges of the fourth and fifth toes are often fused together (symphalangism). The phalanges of the hand are commonly known as the finger bones. The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the body. A phalanx is named according to whether is are proximal, middle, or distal and its associated finger or toe. The proximal phalanges are those that are closest to the hand or foot. In the hand, the prominent, knobby ends of the phalanges are known as knuckles.
Dianopachysaurus a triangular acetabulum, and a reduced but still quite robust dorsal process. The pubis is round, and has an open obdurator foramen, but the ischium is almost entirely hidden. The femurs are slender and slightly sigmoid, with distinct striations on both ends. They are 14 mm long. The fibulae are slightly longer than the tibiae, at 6.5 rather than 6 mm long. The astragali are larger than the calcanea, but both have flat proximal margins. The first metatarsals are distinctly shorter than the others, and many metatarsals are covered by phalanges and so not fully visible. Enough phalanges are preserved
