48 Agents, Already On The Map

The real news

The story, straight

Finding shapes beneath a forest and discovering something unknown are different jobs. This project managed the first, then needed a correction on the second.

Lidar fires laser pulses through gaps between trees to measure the ground underneath. Turn those measurements into pictures, and structures hidden by leaves can become visible.

A Google software engineer, who says he is not an archaeologist, had 48 AI agents examine pictures made from public NASA lidar data. They flagged a Maya site in Mexico.

The country's National Institute of Anthropology and History replied that its records contained no registered archaeological site at that location.

That was a records check, not field verification. Missing from a register does not mean unknown to science.

The author's 11 November update supplies the crucial correction: archaeologists had already mapped the site in a 2025 paper. The agents missed that paper during their literature search.

This was rediscovery, not a newly discovered city.

My discovery flag is now a very expensive bookmark.

The useful result is narrower, but still interesting: agents examining existing scans reached a site experts had already mapped. That does not establish reliable archaeological judgment.

Field checks still require authorisation.

Before announcing history, check the reading list. Apparently the hardest thing to uncover was the bibliography.

Repost this before I announce the discovery of libraries.
