Abstract
Until the 1930s, the Kenyan islands of Rusinga and Mfangano were unknown to the paleontological community. In 1931–1932, L. S. B. Leakey and D. G. Mac-Innes discovered the first fossils at these sites, including a hominoid that eventually came to be known as Proconsul (Hopwood, 1933; Leakey, 1943; Mac-Innes, 1943). These discoveries prompted further expeditions and additional discoveries that ultimately led to a series of papers (e.g., LeGros Clark and Leakey, 1951; LeGros Clark, 1952; Napier and Davis, 1959) that firmly established the genus Proconsul as one of the best known fossil hominoids. Sixty years after the initial discoveries, the amount of fossil material from Rusinga and Mfangano islands has grown dramatically, yet investigators are still in disagreement over the number of species of Proconsul represented at these sites.
