2014年10月28日《美国科学院院刊》刊发了中科院古脊椎动物与古人类研究所张弥曼等研究人员的最新成果:《早白垩世七鳃鳗幼体化石的发现揭示其三阶段的生命周期》。张弥曼等人的新发现,不仅首次记录了化石七鳃鳗的幼体和变态期幼体特征,而且显示现代七鳃鳗独特的三期生命史早在距今1.25亿年前的早白垩世晚期即已成型并保持至今。七鳃鳗和盲鳗是仅存的现生无颌类脊椎动物。地质历史上,无颌类在古生代曾经十分繁
October 28, 2014 The Proceedings of the National Academy of Sciences publishes the latest findings by researchers such as Zhang Miman of the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences: “The discovery of the larvae of Early Cretaceous lamprey reveals its three-phase Life cycle”. The new findings of Zhang Miman et al. Not only recorded the characteristics of larvae and metamorphosis larvae of lamprey lamplamps for the first time, but also showed that the unique three-stage life history of modern lampreh lamp plants was as early as the Early Cretaceous 125 million years ago That has been formed and maintained so far. Lamphel and eel are the only living jawless vertebrates. Geological history, jawless in the Paleozoic has been very complicated
