Patterns of faciodental sexual dimorphism in Hispanopithecus.

Abstract

This paper examines patterns of sexual dimorphism within the Spanish hominid Hispanopithecus. The inclusion of this genus within the Hominidae suggests that extant male and female great ape sexually specific characters are appropriate features for determining the sex of these fossil hominids. It is shown that Hispanopithecus has a distinct sexually dimorphic pattern from that observed in the extant great apes. It is also demonstrated that H. laietanus and H. crusafonti each have a distinct sex pattern from each other. This result further supports the dual species hypothesis.
