Researchers in China have discovered a well-preserved impact crater in Guangdong Province, dating to the early-to-mid Holocene epoch around 11,700 years ago. The 900-meter-wide Jinlin crater is the largest verified from this period, surpassing Russia's Macha crater. It provides new insights into recent meteorite strikes on Earth.
