Tarsioid

1991, Hominidae, entry in Joan C. Stevenson, Dictionary of Concepts in Physical Anthropology, page 201, Cope derived anthropoids from an extinct fossil tarsioid; he suggested that apes and humans evolved from a prosimian and skipped the monkey stage. Hubrecht noted that tarsioids were different from lemurs and more like higher primates (monkeys, apes, and humans).

Among the short-lived northerners were Metacheiromys, whose South American cousins survive today in the order of armadillos, anteaters and sloths, and the early primates — lemurs like Notharctus and tarsioids like Tetonius.

The living Tarsius, of Southeast Asia, is a lone leftover of a once diverse group of small primates, the tarsioids, which flourished during the Eocene in Europe, Asia, and North America.
