discovered talus bones found at Gour Lazib, which they claimed were more similar to those of living strepsirrhines and extinct adapiforms, not simians. The tali morphology also differed radically from those of plesiadapiforms, confirming that azibiids are true primates. Anatomy and physiology All known azibiids were small-bodied primates. The body mass of Algeripithecus minutus was estimated between , equivalent in size to a hairy-eared dwarf lemur (Allocebus trichotis) or the brown mouse lemur (Microcebus rufus). Azibius trerki was estimated to weigh between , comparable in size to a gray mouse lemur (Microcebus murinus). An unnamed species, cf. Azibius sp., was larger, weighing between , making it similar in size to sportive lemurs (Lepilemur). Distribution Both Azibius and Algeripithecus have only been found in the Glib Zegdou Formation of the Gour Lazib area in Algeria. The Glib Zegdou Formation dates to the late early or early middle Eocene. Two upper molars found in Chambi, Tunisia, which were originally associated with Djebelemur martinezi (another suspected stem lemuriform), may instead represent another primate more closely related to Algeripithecus.
