Açutuba and lower Negro settlement sequences
Açutuba (site or scholarly name, not an established ancient self-designation)
Açutuba provides an important regional sequence through survey, excavation and ceramic research. Several occupation components and changing spaces require more than one model of community organization.
Communities, landscapes, and the evidence
Rivers, forests, wetlands, and connections
The lower Negro joins the wider confluence landscape. A Manaus city point does not identify private excavation areas or draw linguistic boundaries.
Political organization and community scale
Changing community scale is investigated from material evidence; the site is not a demonstrated capital of one lower Negro nation.
Colonial transformation, living heritage, and modern reception
Modern research names and sequences are revisable. They cannot determine the identity of living river communities.
The 2006 study introduces Açutuba as an archaeological complex rather than a biological population.
The 2008 thesis describes the site's stratigraphic sequence and several research campaigns.
The regional study compares Açutuba with other sites without making ceramic distributions a fixed political map.
A concise, sourced timeline
These milestones are orientation points, not a complete history.
-
Regional sequence develops
The material study distinguishes early components from later assemblages; exact dates depend on context.
-
Modern excavation campaigns
The thesis documents repeated fieldwork and a developing chronology.
Food, craft, language, labor, and belief
Languages named in this profile
- The registered evidence does not securely establish every resident's spoken language; no language is assigned from material style alone.
Language family: No secure assignment from this evidence
A site name and a phase name are different uses of a term.
A long sequence is not proof of uninterrupted ethnic continuity.
