microfossils 中文意思是什麼

microfossils 解釋
微體化石
  1. The origin and evolution of land plants was an important event in the history of earth life and has affected all other lives on the earth and global environment. during the past two decade, the new discoveries of fossil plants microfossils and megafossils from the mid - ordovician through all silurian to the lower devonian improved knowledge of the origin of land plants, provided a time framework of the basal groups for the land plants and the early evolution diversity of vascular plants. three new plant based epochs have been recognized. on the other hand, molecular sequence studies have provided insights into the phylogeny and early branches of land plants. a phylogenetic tree has been established by the joint of a study of comparative morphology and gene sequences. this paper summarizes recent advances and new knowledges, comments on the phylogenetic studies based on the cladistic analysis

    陸生植物的起源和演化是地球生命中的重大事件，它影響到地球上所有的其他生命和全球環境。在過去的20年中，從中奧陶世歷經整個志留紀至早泥盆世的巖層中，化石植物微化石和大化石的新發現改變了人們對陸生植物起源的認識，並且為陸生植物和維管植物早期演化分異提供了基部類群分化的時間框架。據此人們識別出地史中的3個陸生植物的時代：始胚植物時代始維管植物時代和真維管植物時代。
  2. First occurrence of acanthodian microfossils from the early devonian of lijiang, yunnan, china

    泥盆世棘魚類微體化石的首次報道
  3. The hard coats of spores and pollen grains are preserved better, forming microfossils

    孢子和花粉粒的堅硬外殼被完好保留下來形成微化石。
  4. Well - preserved autofluorescence properties show a correlation between acritarchs morphology and the intensity of organic cell walls and two groups of microfossils are distinguished

    這也是我國首次用化石藻類熒光與生物屬性關系進行研究的嘗試，為今後利用熒光進行化石藻類分選和超微結構研究作了有益的探索。
  5. Our oldest fossils date to roughly 3. 5 billion years ago, and consist of bacteria microfossils

    我們的最舊的化石約會對大致3 . 5十億年前，和包括細菌microfossils 。
  6. Our initial probes suggested that a relatively thin sedimentary layer, which is black in color, would be the most promising for finding a variety of microfossils

    我們的初步探查顯示，有一層黑而薄的沉積，最有希望找到各式各樣的微化石。
  7. The latest studies show that these rocks are older than the ediacara biota, most likely 580 million to 600 million years old, and thus that the microfossils they contain lived 40 million to 55 million years before the cambrian

    最新研究顯示，此沉積比艾迪卡拉生物群還早，很有可能介於6億到5億8000萬年前，也就是說，裏面微化石的生存年代比寒武紀還早了4000萬到5500萬年左右。
