(230320) -- CHENGDU, March 20, 2023 (Xinhua) -- Wu Xichun arranges his fossil collection at home in Chengdu, southwest China's Sichuan Province, March 7, 2023. Wu?Xichun?is?a?professor at the College?of?Energy?of the?Chengdu?University?of?Technology and an expert in geology. In?the?early?1970s, ?while conducting a geological mapping survey in the?northwestern?part?of?Sichuan?Province, Wu?unexpectedly?discovered?a?reef?group?formed?by?Triassic?siliceous?hexactinellid?sponges. Since then, ?he?has?devoted?himself?to?the?study?on?sponge?reefs?for?nearly?five decades. In?order to study foreign literature, Wu mastered English, Russian, and German, and taught himself Latin, Greek, and Old French. He spent years conducting tens of times of on-site investigations at the discovery area to obtain more accurate research results and brought back dozens of pounds of fossils by himself. To clarify the reproduction and migration of hexactinellid sponges, Wu also brought the fossils abroad for more in-depth comparison studies. Wu's research has filled the gaps in the geological history of sponge evolution and solved the mystery of the origin of Jurassic siliceous sponges and sponge reef groups in Europe. "Paleontological fossils are important bases for retracing the history of the Earth. By studying fossils, people can understand the paleogeographic landscape and grasp the laws of Earth's evolution, " Wu said. (Xinhua/Liu Kun)
