Document Summary
Plio-pleistocene: pertaining to the pliocene and first half of the pleistocene, a time range of 5-1 mya. For this time period, numerous fossil hominins have been found in africa. Earliest fossils identified as hominins been as early as 7 mya and after 4mya fossils became more plentiful: hominins evolved from earlier primates dating back close to 50 mya. The earliest primates were diverging from early and still primitive placental mammals (75-65 mya) They may be related to ancestors of the prosimians the lemurs and lorises (strepsirhines) There are bits from north and south america that relate only to the new world monkeys. Early oligocene continental drift had separated new world (the americas) from the old world (africa and eurasia) Late eocene or early oligocene primitive monkeys arose in africa and later reached south america by rafting. Apidium represented by several dozen jaws or partial dentitions as well as many postcranial remains.
