Elephant bird "A. maximus" and "D. stirtoni" were revised to 540 and 730 kg, respectively. Four species are usually accepted in the genus "Aepyornis" today, but the validity of some is disputed, with numerous authors treating them all in just one species, "A. maximus". Up to three species are generally included in "Mullerornis". Several ratites outside of Madagascar have been posited as "aepyornithid"-like and could potentially make this clade considerably more speciose. These include "Eremopezus" from the Eocene of North Africa, unnamed Canary Island remains and several Neogene taxa in Eurasia. "Aepyornis maximus" is commonly known as the 'elephant bird', a term
African elephant date between forest and savanna elephants was 2.6 – 5.6 million years ago, similar to the divergence date estimated for the Asian elephant and the woolly mammoths (2.5 – 5.4 million years ago), which strongly supports their status as separate species. Forest elephants were found to have a high degree of genetic diversity, perhaps reflecting periodic fragmentation of their habitat during the climatic changes of the Pleistocene. However, recent DNA sequence analysis indicates that the extinct European straight-tusked elephant, "Palaeoloxodon antiquus", is closer to "L. cyclotis" than "L. cyclotis" is to "L. africana", thus invalidating "Loxodonta" as currently recognized.
