## In brief

- Researchers report some of the oldest known rocks on Earth, dating to about 3.95 billion years, found in northern China.
- Earth is estimated to be about 4.5 billion years old, and rocks from its earliest period are extremely rare.
- The find is presented as shedding light on Earth's early history.

## Why it matters

Rocks from the earliest part of Earth's history are rare, so new dated samples give geoscientists direct material for testing ideas about the planet's early conditions.
