  • Title: Qualitative comparison of the cranio-dental osteology of the extant elephants, Elephas Maximus (Asian elephant) and Loxodonta africana (African elephant).
    Author: Todd NE.
    Journal: Anat Rec (Hoboken); 2010 Jan; 293(1):62-73. PubMed ID: 19937635.
    Abstract:
    Few osteological descriptions of the extant elephants and no detailed morphological comparison of the two genera, Elephas and Loxodonta, have been done in recent years. In this study, 786 specimens of extant elephants (crania, mandibles, and molars) were examined for characters unique to each species. Differences between sexes in each species were described, as well as differences between subspecies of each species. Striking differences in morphology were noted between sexes of both elephants and between subspecies, which may complement current genetic studies, the focus of which is to determine division at the subspecies or species level, particularly differences between the savanna elephant (Loxodonta africana africana) and the forest elephant (Loxodonta africana cyclotis). In addition, examination of the two living elephants provides an excellent dataset for identifying phylogenetic characters for use in examining evolutionary relationships within and between fossil lineages of elephantids.
