Resumen:
The mandible shape was difference among eatery class (juveniles, sub-adults and adults). The RW 1 showed that the smooth molar process being the outstanding deformations. Moreover the RW2 reflected shape variation in the mandible according to molt cycle stage. Thus, the temporal proximity to the phenomenon of moulting and the degree of wear of the incisor process could explain this pattern. This could be explained by the low frequency of consumption of plant debris in juveniles compared with adults. About these results it is possible to argue that mechanical destruction of this item would accelerate the erosion of the mandible. Adding to this, the longest period of time between ecdysis events maybe explain these results.
