The Maricoxi in the Roosevelt-Rondon expedition literature

Record summary

The Maricoxi is an alleged wild or hostile people described in accounts associated with Theodore Roosevelt’s 1913–1914 expedition down Brazil’s River of Doubt, especially later publications based on expedition testimony. It matters to unknown-creature research because later writers sometimes recast the episode as evidence for an ape-like or “wild man” population. The primary material concerns an ambiguous human encounter, not a confirmed nonhuman animal. Identification, translation, and the degree of firsthand observation require careful checking against Roosevelt’s and Rondon’s expedition texts.
