Claims about Ingá Stone (Pedra do Ingá / Itacoatiaras do Rio Ingá)
- A gneiss riverbed outcrop densely engraved with petroglyphs
- Heritage protection: IPHAN tombamento and UNESCO Tentative List
- Technique and motifs: pecking/polishing, mostly non-figurative
- Dating remains uncertain; wide ranges are proposed
- Conservation threats are well documented (flooding, weathering, visitation)
- Myths proliferate (treasure, aliens, 'writing') amid information gaps
- A 2025 state conservation unit aims to improve protection and visitation
