Turn 4.6 billion years into a walkable timeline
Map geological time onto a real corridor or walkway. Set your available length, choose an Earth-history window, and get event positions, a printable activity and teaching prompts. Free to use, no signup, with English and Chinese versions and source links. AI-assisted; teaching ages and timings are planning guidance, not classroom-trial results.
Extinct Atlas: Deep-Time Walkway allows users to create a walkable timeline of Earth's geological history by mapping events onto a specified corridor length. The tool is free to use, available in English and Chinese, and includes printable activities and teaching prompts, though the suggested ages and timings are for planning purposes only.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
