The fossils of this species are the oldest known fossils featuring the horizontal tooth displacement seen in modern elephants. The species is estimated to have weighed {{convert|484|kg|abbr=on}} and stood about {{convert|1.3|m|ft|abbr=on}} at the shoulder, much smaller than modern species. The name Eritreum comes from the name Eritrea a country in the Horn of Africa where the specimen was discovered, and melakeghebrekristosi in honor of the farmer, Melake Ghebrekristos, who found the specimen.
