Dr. Jin Xingsheng from Zhejiang Museum of Natural History in China cooperated with professors from Montana State University in the USA discovered penicillium fossils on the surface of the turtle eggshell fossils when studying the turtle egg fossils in Tiantai, Zhejiang Province, China. It is essential to find out by a scientific means whether the penicillium discovered on the surface of the turtle eggshell was fossils. Ultimately, the penicillium was affirmed to be fossils by experiments and chemical analysis.
This result, titled Fungus Fossils on Chinese Turtle Eggs in the Cretaceous—Evidence of Ecological Functions was published last month on Palaios, an American authorized journal on paleontology and sedimentology. It has been so far the earliest penicillium fossils, which played a great importance in the research of paleoecology.
