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

A staff member places models of restored Eosteus chongqingensis (L) and Megamastax amblyodus at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences (CAS), 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."
