On February 1, a team led by Professor Wang Shuo of Qingdao University of Science and Technology published a cover paper titled “The discovery of a South African Flame-tolerant Rhonaceae from Amber 100 million years ago” on the international journal Nature Botany.In this study, we found for the first time in the world complete flower fossils with in situ pollen from The Mesozoic Rhamnoides, providing important fossil evidence for the study of the relationship between the evolution of early flowering plants and plate movement in Southeast Asia.Fossil amber of the genus Phylica, rhamlidae, formed about 100 million years ago.Qingdao university of science and technology for the figure according to introducing, the results of the study is a team of researchers led by professor wang shuo Qingdao university of science and technology and nanjing geological paleontology research institute, Chinese Academy of Sciences, kunming institute of botany, Chinese Academy of Sciences, liaoning fushun research institute of amber and fujian agriculture and forestry university, as well as the Open University, the university of Bristol, and South Africa’s biodiversity research institute in close cooperation,It took eight years.Reconstruction of the northward drift of the Phylica ancestors with the Indian plate.Wang and his team, from Qingdao University of Science and Technology, studied more than 20 amber fossils dating back about 100 million years. By comparing their surface features and internal three-dimensional structures with the morphological structure of living plants, they finally found the living descendants of these amber fossils in the Cape Flora of South Africa.These preserved in amber fossil plants in the Indian plate and gondwana took shape with before has not yet been completely separate, with the break-up of gondwana and the Indian plate moving north, the ancestors of the biota spread by the Indian plate to the northern Burma, but their descendants had to survive in the cape province of South Africa.These flowers have blossomed since the Mesozoic era, when dinosaurs flourished, and their flowers, leaves, and coats are highly adaptable to frequent wildfires.The study suggests that the flora of northern Myanmar is linked to that of the southernmost part of the African continent, and that frequent wildfires during the Cretaceous may have been an important driver of angiosperms evolution.An ecological restoration of the amber fossil formation period, in which low-lying plants are Phylica.Gymnosperms originated before Cenozoic era, including ginkgo and Metasequoia are called “living fossils”.The study shows that the extant genus Phylica in the Cape flora has a fossil history of about 100 million years, which is a kind of ancient angiosperms adapted to the habitat of frequent wildfires. It is also worthy of the name “living fossil”.Source: People’s Daily Online Rector: Li Jiaming Audit: Dai Baozhu supervisor: Wang Pengcheng
