Despite the fact that dental evidence is a poor taxonomic indicator for chalicotheres, teeth provide the only evidence available for comparing Schizotherium species. Schizotherium avitum is a relatively small (?) representative of Schizotherium, with long narrow M[subscript]3, lower molar trigonid not wider than talonid, narrow M[subscript]3 hypoconulid, and metastylid weaker than in S. ordosium, S. priscum, or S. turgaicum but stronger than in S. chucuae. Schizotherium nabanensis resembles S. avitum in many respects but is poorly known. Derived characters of the metastylid and M[subscript]3 hypoconulid suggest that S. avitum may be closest to S. chucuae among other Schizotherium species. Material des... |
