Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. J. Sanders 2007 | Primitive loxodont elephant retaining permanent third and fourth premolars. Distinguished from L. adaurora, L. exoptata, L. atlantica, and L. africana by fewer molar plates, especially in posterior teeth, and lower hypsodonty indices, and from non-loxodont elephants by presence of anterior and posterior accessory conules and tendency for enamel rims of plates to form median sinuses with wear, throughout molar crowns. |
