Balucatherium fed strictly on plants. Because of its enormous height and long neck, Balucatherium probably fed on the leaves of tree tops as does the giraffe of today. Like elephants of today, Balucatherium probably lived in small family groups taking advantage of the scattered trees found in dry open woodlands.
