 (781,000–50,000 years before present). Some experts regard the smaller Asian species E. namadicus, as a variant or subspecies of this one.

Description

The creature was 3.90 m (12 ft) tall and had long, slightly upward-curving tusks. E. antiquuss legs were slightly longer than those of modern elephants. It is suggested that this elephant had a 80 cm long tongue that could be projected a short distance from the mouth to grasp leaves and grasses. With this tongue along with a flexible trunk, straight-tusked elephants could graze
