binomial_authority =Dietrich , 1894"Elephas recki" is an extinct species of African
elephant . At up to 15 feet (4.5 metres) in shoulder height, it was one of the largest elephant species to have ever lived. It is believed that "E. recki" ranged throughout Africa between 3.5 and 1 million years ago. TheAsian Elephant is the only extant member of the genus. "E. recki" was a successful grass eating elephant that lived throughout thePliocene and thePleistocene until it was pushed to extinction in competition with members of the genus "Loxodonta ", theAfrican elephants of today.ubspecies

* "Elephas recki brumpti" Beden, 1980
* "Elephas recki shungurensis" Beden, 1980
* "Elephas recki atavus" Arambourg, 1947
* "Elephas recki ileretensis" Beden, 1987
* "Elephas recki recki" (Dietrich, 1916)New research indicates that the ranges for all five subspecies overlap, and that they are not separated in time as previously proposed. The research also found a wide range of morphological variation, both between the supposed subspecies and between different specimens previously identified as belonging to the same subspecies. The degree of temporal and geographical overlap, along with the morphological variation in "E. recki" suggests that the relationships between any subspecies are more complicated than previously indicated.
