Etymology

The earliest attestation of the word manuport is from English in 1966. The term is derived from the Latin words ''manus'', meaning ‘hand’, and ''portare'', meaning ‘carry’.

argues that the cobble must have, sometime around 2.95 million years ago, been picked up and “carried for a considerable distance” by an early hominin. The Makapansgat cobble is the oldest known manuport and is possibly the earliest example of symbolic thinking. The Makapansgat cobble’s distinct ‘face’, with its pair of ‘eyes’ and a ‘mouth’, has led some researchers to conclude that the profile must have, at least partially, been carved by hand. However, current research suggests that the cobble’s ‘features’ are entirely the result of natural forces. During the

typical of sand dunes and reefs that have dried out. The exposed portion of the chert measures 40mm wide by 35mm high. Chemical analysis has determined the calcrete’s age to be 41,000 years old, indicating the earliest possible date that the manuport was deposited. This supports other archeological discoveries on the island suggesting humans occupied Barrow Island as early as 53,000 years ago. Collectively these artifacts present one of the oldest examples of maritime resource exploitation outside of Africa. Australian archeologists have noted that calcrete is an ideal medium for preservation and the finding of the Barrow Island manuport is a strong indication further artifacts are likely to be located along Western Australia’s limestone shelf.

Ambiguous manuports

It is not uncommon for ‘alien’ lithics to be found alongside other artifacts during archaeological excavations. Discerning whether certain stones are, indeed, manuports is difficult. There is no set criteria for determining a manuport and this designation is often provided at the researcher’s discretion.

, archeologists uncovered 799 possible manuports from inside Spirit Eye Cave. Hundreds of unmodified, polished pebbles were uncovered, organized alongside other ‘cultural material’ that indicates human presence during prehistory. Sedimentary analysis indicates that these pebbles were deposited possibly 4,200 years BP. Researchers have suggested that this collection represents a portable form of ‘pebble art’, although their meaning is difficult to conclusively discern. The pebbles demonstrate a striking uniformity. The leading theory proposed by archeologists is that these stones are
gastroliths A gastrolith, also called a stomach stone or gizzard stone, is a rock held inside a gastrointestinal tract. Gastroliths in some species are retained in the muscular gizzard and used to grind food in animals lacking suitable grinding teeth. In oth ...
. Whether they were deposited after birds had died ''in situ'' or later collected by humans is still up for debate, though cultural significance of the stones should not be ruled out. Given the technological prominence of stones in prehistory, there is a myriad of possible ‘cultural meanings’ these gastroliths represent. One explanation offered is that these stones, given their smaller size, could have made for effective projectiles. Another explanation suggests that, like other contemporary prehistoric cultures, the Spirit Eye Cave manuports may have been spiritually ‘eaten’ (or placed in the mouth) as part of a lithophagic ritual.


Manuport size and hominids

Manuports can reveal to archeologists what some of the cultural practices of early hominids were. A collection of 176 manuports found in Olduvai,

are believed to have been deposited sometime around 1.8mya. Measuring the collection reveals two clear groups of manuports in a ‘deliberate selection and hoarding by a hominid species’. One group demonstrates an average weight of approximately 400g, and the other with an average weight of 220g. A manuport, like a footprint, may indicate the locomotion and mass of the hominid who threw it. It is possible that the collection of manuports found in Olduvai represent selection for
