  • Title: Assessing mandibular shape variation within Gigantopithecus using a geometric morphometric approach.
    Author: Miller SF, White JL, Ciochon RL.
    Journal: Am J Phys Anthropol; 2008 Oct; 137(2):201-12. PubMed ID: 18615565.
    Abstract:
    This study provides a survey of mandibular shape in a sample of extant hominoids (Pan, Gorilla, Pongo, and Hylobates), as well as extinct Asian and Eurasian taxa (Ouranopithecus, Sivapithecus, and Gigantopithecus) in order to compare overall shape similarity. Results presented call into question differences in mandible shape recently used to distinguish Gigantopithecus giganteus from Gigantopithecus blacki and to justify resurrecting a different generic designation, "Indopithecus," for the former. It is concluded that while the two large-bodied Asian taxa may have been adapted to slightly different dietary niches with different geographic and temporal ranges, the unique mandibular/dental characters that the two taxa share should not be viewed as independent evolutionary developments.
