继中华龙鸟、尾羽鸟、北票龙、孔子鸟等轰动世界的远古化石之后,辽西地区化石出土和考古又有重大发现,被命名为“三燕丽蟾”的远古蛙化石,堪称世界第二。 中国科学院古脊椎人类研究所侯连海教授,在古鸟类化石的研究中意外地发现了一块蛙化石。经过两年多野外地质工作和室内研究,研究人员逐步了解了该化石的产出起点、层位及相关的地质占生物信息。它出土于辽宁省北票市四合屯村村西的中生代中期的硅质页岩层中,其时代是距今至少1亿2千多万年前。因为辽西地区的古地名是“三燕”,且该化石保存了完整而精美的骨 Following the ancient Chinese fossils such as the dragon, the tail, the north ticket, the Confucius bird and other sensations in the world, the discovery of fossils and archaeological discoveries in the western Liaoning have also led to the discovery of the ancient frog fossils named “San Yan Lai Toad” second. Professor Hou Lianhai, professor of paleontology and human history at the Chinese Academy of Sciences, discovered a frog fossil accidentally in the study of ancient bird fossils. After more than two years of field geology and in-house research, researchers gradually learned the starting point of production of the fossil, and the horizon and related geology accounted for biological information. It was unearthed in the mid-Mesozoic siliceous shale formation in the west of Sihetun village in Beipiao, Liaoning province, at least 120 million years ago. Because the ancient name of western Liaoning is “San Yan”, and the fossil has preserved the complete and exquisite bone
