Scientists have discovered the oldest mushroom fossil to date prove that the origin of mushrooms is no later than the early Cretaceous period, pushing the origin of mushrooms forward at least 25 million years Guangming Daily Nanjing, March 17 (Reporter Zheng Jinming) by the Chinese Academy of Sciences Nanjing Institute of Geology and Paleontology and New Zealand, the United States paleontologists composed of scientific research team, from many years in Liaoning, Inner Mongolia and Northern Kechin State, Myanmar, Hukang Valley and other places to collect the amber specimens, recently identified four from about 100 million years ago.
four mushroom fossils, formed in the middle of the Cretaceous period, were found to be well-structured and are the oldest mushroom fossils ever found.
Ecological restoration map of mushroom-eating mushrooms by giant bearded crypto-finned insects The Nanjing Institute of Geology and Paleontology is understood to have been carried out by Huang Diying and Cai Chenyang, researchers at the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, in collaboration with scientists from New Zealand and the United States.
they found these four mushroom fossils from more than 20,000 amber specimens formed in the middle cretaceous period 100 million years ago, greatly enriching the diversity of Cretaceous mushroom species.
Cretaceous mushroom fossil photo Nanjing Institute of Geology and Paleontology for the map Huang Diying told reporters, because mushrooms belong to the fungus, lack of a few butyl skin or mineralized shell, also do not have the high plant's edict structure, life cycle is very short and soft texture, it is difficult to save as fossils, increasing the difficulty of research.
past, only one fossil of amber mushrooms from 100 million years ago has been found, but the specimen is poorly preserved, preserving only part of the umbrella cover, which makes it difficult to understand the early evolutionary history of mushrooms.
discovery of the mushroom fossil opens a new window into the early evolution of human cognition of mushrooms.
" four amber fossils found this time contain four new types, all belonging to the Umbrella bacteria.
although they are 2 to 3 mm long, but have a bacterial handle and umbrella cover, the structure is complete.
, these mushroom fossils are very similar to the living mushrooms, providing direct evidence of the diversity of mesothrobacteria.
," Huang Diying told reporters, the discovery greatly enriched the diversity of Cretaceous mushrooms.
addition, this time the archaeology also revised the origin of mushrooms.
"We found a class of giant bearded wingworms that feed exclusively on mushrooms in the same period in Burmese amber and in fossils of early Cretaceous hot river biota about 125 million years ago.
evidence suggests that mushrooms existed in the early Cretaceous period, about 125 million years ago.
discovery pushed the origin of mushrooms forward by at least 25 million years.
" Cai Chenyang said, the emergence of large giant pythons proved the existence of large mushrooms during the Cretaceous period.
" discovery highlights the diversity of mushrooms in the Mesothic period, proves that mushrooms originated no later than the early Cretaceous period, revised the mushroom's 'family tree', and filled the gap in the study of the early evolutionary history of mushrooms.
" Huang Diying said that the research results have been published in the internationally renowned academic journal Nature -Communication, the relevant research has also been supported by the Chinese Academy of Sciences, the Ministry of Science and Technology and the National Natural Science Foundation of China.
