A 512-million-year-old fossil discovery is rewriting Earth's early history.

Scientists from the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (NIGPAS), have uncovered the Huayuan Biota — a remarkably preserved deep-sea ecosystem that formed right after Earth's first mass extinction of complex life.

These fossils show how life not only survived a global catastrophe, but also migrated across oceans and rebuilt entire ecosystems from scratch.

Published in Nature, the discovery gives us a rare window into how biodiversity collapses — and how it recovers.

The past may hold clues to our planet's future.
