The anthropoids from the Fayum Province, Egypt, represent the best-preserved and most diverse assemblage of early anthropoids found anywhere in the world. However, the best known of the Fayum primates—Aegyptopithecus zeuxis, Propliopithecus chirabates, Apidium phiomense, and Parapithecus grangeri— occur near the top of the 340m-deep Jebel Qatrani Formation (Simons, 1965, 1967, 1974, 1987; Kay, 1977; Fleagle and Simons, 1978, 1982a,b; Gebo and Simons, 1987; Kay et al., 1981; Fleagle and Kay, 1983, 1985, 1987). Fossil primates millions of years older have been found at lower stratigraphic levels, and these older species differ appreciably from the primates of the uppermost quarries, reflecting significant evolutionary changes that took place during the time represented by the deposition of the Jebel Qatrani Formation (Simons, 1962; Simons and Kay, 1983; Rasmussen and Simons, 1988). The oldest primates yet found in the Fayum have been described recently on the basis of dental and cranial specimens found at quarry L-41, which lies near the base of the Jebel Qatrani Formation (Simons, 1989, 1990, 1992; Rasmussen and Simons, 1992). These L-41 primates are among the most ancient and structurally most primitive anthropoids found anywhere in the world.
