The Early Fossil Record Of Primates

The early fossil record of primates indicates that the group radiated in the Palaeocene and Eocene. Older records from the Cretaceous are doubtful, although molecular evidence (see p. 324) suggests that the order might have originated in the latest Cretaceous. Could our distant ancestor, a small squirrel-like animal, have seen the last dinosaurs as it peered nervously from behind some branches? The plesiadapiforms are regarded as close relatives ofthe primates (see p.353) and they are sometimes formally included in the Order Primates. Undisputed basal primates include the omomyids, adapiforms and tarsiids.
