Eritreum
''Eritreum melakeghebrekristosi'' is an extinct species of proboscidean mammal, which lived in Northeast Africa during the late Oligocene some 27 million years ago, and is considered to be the missing link between modern elephants and their ancestors. 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 and stood about at the shoulder, much smaller than modern species. ==References==
