Age and Sex-Related Geometrical Variation of Ramus mandibulae of Sus scrofa's (Mammalia: Artiodactyla) Jaws

Morphological variation of the ramus mandibulae of wild Sus scrofa was described and correlated to sex and age differences. Young forms (n=27, 15 males, 12 females) and adults (n=23, 13 males, 10 females) were analyzed through Geometric Morphometrics (2-D) to assess differences between groups. We fo...

Young forms (n=27, 15 males, 12 females) and adults (n=23, 13 males, 10 females) were analyzed through Geometric Morphometrics (2-D) to assess differences between groups.

The ramus mandibulae in female wild boars is more robust and bulky than in males.
