"The Resurrection of Jimber-Jaw" is a 1937 short story by American writer Edgar Rice Burroughs, about an unfrozen 50,000-year-old caveman.
The story was originally printed in Argosy magazine, and later reprinted as one of three stories in the collection, Tales of Three Planets (Canaveral, 1964, 1974). The Argosy text, used for all versions published under this title, contained significant alterations by the magazine editor of Burroughs' original text. Burroughs' original version, "Elmer", was published in Forgotten Tales of Love and Murder (Guidry & Adkins, 2001).
