The Roman numerals denote the ordinal number of each digit present, counting from the inner side of the pentadactyl foot. (2.) For locomotion on dry hard ground, a stronger foot was required, and a modification would soon take place, in the interlocking of the metapodials with the second row of carpals or tarsals that supported them. Examples of nearly this stage are seen in the fore feet of Coryphodon and Dinoceras, as shown in figures 150 and 152, below. The fore foot of the elephant (figure 156) will also serve to illustrate the same stage. (3.) A still stronger foot was produced by the further interlocking of both the first and second row of carpals and tarsals, as well as the latter row with the metapodials below. This general type of foot belongs to the Hohdactyla, and is seen also in some of the early Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marsh, Othniel Charles, 1831-1899.
