RWA for distortion parameter α = 0 of ruminant mandibles obtained from 11 fossil specimens (Bison antiquus, Dicrocerus elegans, Dremotherium feignouxi, Dremotherium guthi, Gelocus villebramarensis, Procervulus dichotomus, Brachitherium cf. curtum, Dorcatherium naui, Iberomeryx minor, Leptomeryx evansi, Nanotragulus loomsi; see Table 2) and 83 extant specimens (see Table 2). 1 Shape deformation grids representing the mean shape (consensus) and the maximum values of the two-first Relative warps (Rw’s). 2 Scatter plots of the first versus the second Rw with taxonomic characterization. The A axis indicates the shape variation of the mandible “warped” from the mean shape (consensus) into the maximum positive deviations in the axis of Rw1; the B axis the shape variation of the mandible “warped” from the mean shape (consensus) into the maximum negative deviations in the axis of Rw1; the C axis the shape variation of the mandible “warped” from the mean shape (consensus) into the maximum positive deviations in the axis of Rw2; and the D axis the shape variation of the mandible “warped” from the mean shape (consensus) into the maximum negative deviations in the axis of Rw2. 3 Indication of the diet. A, B, C, and D axes as in 2
