China team unearths world’s oldest amber, hidden in ancient Xinjiang coal seam

The amber recovered from a coal seam in China's remote Xinjiang region dates to 385 million years ago, establishing it as the world’s oldest known amber. Its age predates the emergence of any land‑dwelling animal, a surprise that overturns expectations that such fossilized resin appears later in the geological record. Chinese scientists uncovered the specimen while examining an ancient coal seam, and the South China Morning Post detailed the find as hidden within the sediment.

Interesting Engineering highlighted that the 385‑million‑year‑old resin shifts the timeline for plant evolution, suggesting that resin‑producing flora existed far earlier than previously documented. Inshorts and Table.Briefings also reported the discovery, underscoring its relevance to paleobotany and the reconstruction of early terrestrial ecosystems. The discovery impacts paleobotanists, geologists and evolutionary biologists who study the origins of land plants.

Researchers plan to analyze the amber’s chemistry and any trapped inclusions to refine models of early plant life. International collaborations are expected to examine the sample using advanced spectroscopy. Future publications are expected to report on detailed laboratory work, potentially revealing new insights into the ecosystems that preceded animal colonization of land.
