Number of shell middens located in the mangrove swamps of the northwest coast of Guyana have been grouped together into the Alaka Phase. An Archaic lifestyle based heavily on shellfish-gathering is indicated throughout. Some crude percussion-made stone tools, manos and metates are present, with crude ceramics appearing in the later stages. These ceramics represent the appearance of intrusive groups and are assumed to mark the passing of Alaka. Dates are hypothetical but range over the period c2000 bc to the early Christian era.
