Koihoma (Coixoma), also known ambiguously as Coto (Koto) and Orejone (Orejón), neither its actual name, is an extinct, apparently Witotoan language of Peru.[1]
In Steven Spielberg's film Indiana Jones and the Kingdom of the Crystal Skull (2008), Indiana Jones identifies Koihoma language on a mysterious letter written by Harold Oxley, although he explains to Mutt Williams that nobody speaks that language anymore. He quite contradictorily defines it a "Latin American language" that became extinct centuries before Spanish and Portuguese were introduced to the Americas.
