Lost & Ancient.

What this pillar covers

Lost & Ancient differs from the other pillars in tempo. A declassified-files case opens when a document drops. A UAP case opens when a video releases. An ancient case opens when an excavation finishes a season, or when carbon-14 dating gets recalibrated, or when a paper reaches publication after years of peer review. The cases move slowly because the evidence is buried, in many cases literally.

That slowness is also why this pillar tends to be evergreen. The Antikythera Mechanism was discovered in 1901 and is still being studied; new internal scan results were published in 2021. Göbekli Tepe's existence has been known since the 1960s and its significance for the prehistory of religion is still being argued over. The same case file might be revised five times across a decade without becoming irrelevant.

How we handle pseudoarchaeology

This pillar attracts more pseudoarchaeology than the others. The boundary we use: a claim belongs here only if there is verifiable physical evidence and the dispute is between credentialed experts (e.g., the Sphinx weathering debate, the Younger Dryas hypothesis) or between credentialed experts and a single high-profile outlier with primary data of their own (e.g., the Gunung Padang controversy). Claims that depend entirely on a popular author with no original fieldwork — "Atlantis was actually in Antarctica," "Egyptians had electric batteries powering pyramid lighting" — get files that document the claim, identify its origin, and explain why mainstream archaeology rejects it.

We don't write off entire fields. Recent work at Göbekli Tepe and Karahan Tepe has substantially revised the timeline of human social organization. Some "fringe" claims have moved toward the mainstream. The case files note which way the consensus is moving, when it's moving.
