Palaeomastodon had tusks, both upper and lower, and it had a trunk. It was about 2.2 metres (7 ft 3 in) tall at the shoulder and weighed about 2.5 tonnes (2.5 long tons; 2.8 short tons).[2] The lower tusks were flat rather than pointed cones, and were probably used to scoop plants from swampy water.

Palaeomastodon was known to have their ears located towards the top of their heads, to make sure their sensory organs remained dry. In addition, their sharp tusks were used as a defense weapon.[3]
