Indian rock yields oldest directly dated evidence of microbial life
A 3.5-billion-year-old layered rock found near Jamshedpur in Jharkhand preserves carbon biosignatures from Earth's earliest microbes.
What to know
- A 3.5-billion-year-old layered rock (chert) discovered near Jamshedpur in Jharkhand, India contains carbon biosignatures interpreted as evidence of microbial life.
- The findings, published in the Proceedings of the National Academy of Sciences, represent potentially the oldest directly dated evidence of life on Earth.
- The rock's layered structure and carbon-rich composition are key to the biosignature interpretation.
“A team of researchers reports that they may have found rock containing some of the earliest forms of microbial life on Earth.”
