The morphology of
Archicebus indicates that it is one of, if not exactly the last common ancestor of all primates from humans to monkeys. The largest similarities between primates and
Archicebus are found in the metatarsals and the ankle, particularly the calcaneus. These bones are similar in shape and proportion to those seen in later primates.
Archicebus, however, also possesses a skull, teeth, and limb bones that are much more common to a group
of lower mammals (tarsiers).
