Navicular and cuboid bones of tarsus united.
The astragalus has a pulley-like surface above for articulation into the tibia, but its lower surface is flattened and unites to a much greater extent with the navicular than with the cuboid, which bone is of comparatively less importance than in the Artiodactyles.
Lower articular surface of the astragalus divided into two nearly equal facets, one for the navicular and a second for the cuboid bone.
N T avicular and cuboid bones of tarsus distinct.
I A), and never fuse into a complete cannon-bone;, and the navicular and cuboid bones of the tarsus are separate.
The trapezoid and magnum of the carpus, and the cuboid and navicular of the tarsus are distinct.
The cuboid is small, and the internal and middle cuneiform bones are small and united together.
Navicular, cuboid and ectocuneiform bones of tarsus united.
A few barrel weights are found at Karnak, and several egg-shaped shekel weights at Gebelen (44); also two cuboid weights from there (44) of 1 and 10 utens are marked as 6 and 60, which can hardly refer to any unit but the heavy shekel, giving 245.
Although the brain is relatively larger, the bones of the limbs, especially the short, five-toed feet, approximate to those of the Amblypoda and Proboscidea; but in the articulation of the astragalus with both the navicular and cuboid Arsinoitherium is nearer the former than the latter group. It is probable, however, that these resemblances are mainly due to parallelism in development, and are in all three cases adaptations necessary to support the enormous weight of the body.
The large weights of ounces and pounds are disks or cuboid blocks; they are dated from 720 to 785 for the lesser, and to A.D.
