Analysis of the stratigraphic records of 19,897 fossil genera indicates that most classes and orders show largely congruent rises and falls in extinction intensity throughout the Phanerozoic. Even an ecologically homogeneous sample of reef genera shows the same basic extinction profile. The most likely explanation for the congruence is that extinction is physically rather than biologically driven and that it is dominated by the effects of geographically widespread environmental perturbations influencing most habitats. Significant departures from the congruence are uncommon but important because they indicate physiological or habitat selectivity. The similarity of the extinction records of reef organisms and the marine biota as a whole confirms that reefs and other faunas are responding to the same history of environmental stress.
对19897个化石属的地层记录分析表明，在整个显生宙，大多数纲和目在灭绝强度上呈现出大致一致的上升和下降趋势。即使是珊瑚礁属的生态同质样本也显示出相同的基本灭绝模式。这种一致性最可能的解释是，灭绝是由物理因素而非生物因素驱动的，并且它主要受影响大多数栖息地的地理上广泛分布的环境扰动的影响。与这种一致性有显著偏差的情况并不常见，但很重要，因为它们表明了生理或栖息地选择性。珊瑚礁生物和整个海洋生物群灭绝记录的相似性证实，珊瑚礁和其他动物群对相同的环境压力历史做出了反应。
