Ancient Chinese fish fossils fill critical gap in "fish to human" evolution

Zhu You'an, a researcher with Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences (CAS), studies the fossil of Eosteus chongqingensis at the IVPP, in Beijing, capital of China, March 3, 2026. Fossils of two fish from over 400 million years ago -- one a tiny streamlined creature, the other a giant among vertebrates of its time with bizarre teeth -- have been discovered in China, filling a critical gap in the evolutionary journey "from fish to human."
