In 1961, three friends hunting for geodes in California's Coso Mountains cracked open a rock to find something that seemingly defied time: a mechanical object encased in ancient stone. Was the Coso Artifact a relic of a lost civilization, or is there a more grounded explanation hidden in the geological crust?

In this episode of Unexplained History, host Tom McKenzie dives into the world of Out-of-Place Artifacts (OOPArts). We explore the friction between sensationalist media claims and the rigorous methods of professional archaeology. From the spark plug-like interior of the Coso find to the complex gears of the Antikythera Mechanism, we examine how context, provenance, and modern imaging like CT scans separate genuine historical wonders from long-standing myths.

Join us as we investigate the figures who shaped these narratives—from antiquity dealers like Eugene Boban to dedicated researchers like Tony Freeth—and discover why some "mysteries" persist long after the evidence has spoken.
