Zebras from Wonderwerk cave, northern Cape Province, South Africa: attempts to distinguish Equus burchelli and E. quagga.
Measurements obtained from Equus burchelli and E. quagga specimens in various museum collections are compared against corresponding measurements on equid teeth from Holocene deposits at Wonderwerk cave, situated near the N limit of the historically known distribution of the partially striped (now extinct) E. quagga and near the S limit of E. burchelli. Entoflexid length of the 4th lower premolar appears to be a potential parameter for distinguishing the 2 taxa. Results support a suggestion that E. quagga may have been a S variant of E. burchelli, rather than a distinct species.-Author
