泥盆世棘魚類微體化石的首次報道 - 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。 - 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 。 - In the summer of 2003 we began to zero in on one microfossil type whose complex morphological characteristics particularly intrigued us
2003年夏天，我們開始瞄準一種微化石的類型，其復(fù)雜的形態(tài)特徵特別引起我們興趣。 - 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。 - We know from microfossil evidence that living cells existed on earth some 3 . 5 billion years ago , and these bear a striking resemblance to microorganisms we find today in geothermal springs
從微體化石的證據(jù)顯示，細胞早于約3 . 5億年前便已存在，它們竟和現(xiàn)時在溫泉中發(fā)現(xiàn)的微生物十分類似。 - Well - preserved autofluorescence properties show a correlation between acritarchs morphology and the intensity of organic cell walls and two groups of microfossils are distinguished
