Chinese palaeontologists have discovered a rare group of paleontology in Helen, Heilongjiang Province

, Oct. 30 (Xinhua Cheng Zilong) China's three palaeontologists, after careful investigation, found a series of plant and animal fossils found in the city of Yuhua Helen, Heilongjiang Province, a rare Cretaceous biota here. This paleontum is rich in biological species, including fern stem fossils, wood fossils of naked plants, and dinosaur fossils and moth fossils.
Cretaceous biota is located in the forest farm of The Wells store in Helen City, 75 km from downtown Helen. In the well shop forest farm there is a canyon, the canyon on the back of Xiaoxing Anling, down to Helen City, the upper reaches of the Oriental Red Reservoir, the valley length of more than 10 kilometers. Numerous plant and animal fossils have been found in the gray-green sandstone of the canyon mountains and under the rivers on both sides.
Cheng Yesing, a professor at the China Geological Museum and chairman of the Paleoflora Branch of the Chinese Botany Society, led a team that visited the canyon in Helen from June to September 2018 and found that the fossils included stem fossils of ferns as well as fossils of bare-bore plants such as sulphs and pine cypresses. Ferns include groups such as Dempski, Zixuan and Cyano. These fossils are of great significance to the study of the evolutionary history of ferns and the ancient environment at that time.
Liu Fengxiang, a senior engineer at the China Geological Museum and
a science researcher with the Chinese Society of Paleontology
, said the group of wood fossils fills a gap in domestic research. Previously, in 2017 and 2018, their research team found fossils of radon and Dempsky in Keshan County, Qiqihar City, Heilongjiang Province.
, an associate researcher at the Beijing Museum of Natural History, also visited Helen in September. He introduced that in Helen Canyon found large pieces of dinosaur fossils and moth fossils, the discovery of the fossil is the first time in China. Wang Baopeng believes that the discovery of Helen's paleontical group proves that there existed a complete ecosystem here in ancient times, which is of great significance to the study of ancient climate.
