真菌和地衣的化石记录很少。在这里,我们报告了在中国南方瓮安陡山沱组(距今551至6.35亿年)海相磷岩中发现的地衣样化石,其中包括与球状蓝藻或藻类密切相关的丝状菌丝。这些化石表明,在维管植物进化之前,真菌就与光合自养生物形成了共生伙伴关系。
The fossil record of fungi and lichens is scarce. Here we report the discovery of lichen-like fossils, involving filamentous hyphae closely associated with coccoidal cyanobacteria or algae, preserved in marine phosphorite of the Doushantuo Formation (between 551 and 635 million years old) at Weng'an, South China. These fossils indicate that fungi developed symbiotic partnerships with photoautotrophs before the evolution of vascular plants.
