Species of Megapedetes were larger, relatively low-crowned (brachydont) pedetids with short, mostly fused roots under their teeth.

An isolated phalanx from a slightly older site, Auchas Mine, cannot be reliably identified to species level,[1] but may be M. gariepensis.

[3] M. pentadactylus, the type species of the genus, occurs at Songhor, Rusinga, and Bukwa;[6] a species that may be close to M. gariepensis is known from Kirimun, Fort Ternan, and Maboko; a pedetid from Kipsaraman resembles M. pickfordi, but is more low-crowned; and other pedetids may occur in other East African sites.

[5] Another species, Megapedetes aegaeus, occurs at Bayraktepe in Turkey[9] and the genus has also been found on the Greek island of Chios.

[5] Among the two Arrisdrift species, M. gariepensis is about 15% smaller than the East African M. pentadactylus and more adapted to jumping and has less robust incisors, more high-crowned (hypsodont) cheekteeth.
