在海面上

In view of geological records preserved from different regions of the world are not identical, it's suggested that, when correlating the Ordovician-Silurian boundary, at the global boundary stratotype section, the FAD of N. persculptus be selected as the biomark, the transgression event identical to the FAD of N. persculptus as the auxiliary physical mark and the mass extinction and chemical anomaly events respectively as the auxiliary biomark and chemomark. In some regions with few graptolite, the Ordovician-Silurian boundary should be indicated by the auxiliary marks, such as the transgression event, mass extinction or chemical anomaly event, with the other fossil such as conodont nearest to other geological events as the provincial biomark for correlation. In other regions with much stratigraphic hiatus originated from the regression, the Ordovician-Silurian boundary should be marked by the regression-transgression event nearly relevant to the N. persculptus Zone.

鉴于不同地区留下的地质记录不完全相同，奥陶/志留系界线对比方法不同：在界线层型剖面上，以N.persculptus的首现为生物标志，以与之基本一致的海侵事件为辅助的物理标志，以生物集群绝灭事件和化学异常事件为辅助的生物和化学标志；在笔石极不发育的地区，则以海侵事件、生物绝灭事件或化学异常事件为辅助标志，以与其相距最近、并且具有区域对比性的其它门类化石作为界线对比的生物标志；对于由于海退事件所造成地层缺失很多的地区，则以海退/海侵事件作为划分界线的物理标志，并以相映的海侵事件的开始作为奥陶/志留系的分界。

They were, says Mr Stephen, and the end was that the men of the island seeing no help was toward, as the ungrate women were all of one mind, made a wherry raft, loaded themselves and their bundles of chattels on shipboard, set all masts erect, manned the yards, sprang their luff, heaved to, spread three sheets in the wind, put her head between wind and water, weighed anchor, ported her helm, ran up the jolly Roger, gave three times three, let the bullgine run, pushed off in their bumboat and put to sea to recover the main of America.

此语不差&，斯蒂芬先生曰，&其结果，本岛男子发现负情女子异口同声，无可救药。遂建造舟筏，携家财登船，桅杆尽皆竖起，举行登舷礼，转船首向风，顶风停泊，扬起三面帆，在风与水之间挺起船首，起锚，转舵向左，海盗旗迎风飘扬，三呼万岁，每次三遍，开动舱底污水泵，离开兜售杂物之小舟，驶至海面上，航往美洲大陆。&&
