灭绝事件通常会破坏古生物地理格局,但很少有详细的研究早志留世的生存恢复期后,晚奥陶纪大灭绝。本文总结和修订已发表的资料恢复早期和晚期Rhuddanian腕足动物群。全球数据集包括137个事件,72属,和13个地点的早期Rhuddanian(生存间隔),和271个事件,91属,和26个地点的晚期Rhuddanian(早期恢复间隔)。使用聚类分析、非度量多维标度和最小生成树(使用Yule的Y系数和Raup-Crick系数(相似性的概率指数))对数据进行分析。研究结果揭示了腕足动物生存和恢复过程中的古纬度分布规律。频率分析的数据表明,世界性的类群在大灭绝前减少了灭绝后的分布。幸存者在生存期内大多局限于一个古板块甚至一个地点,但在随后的恢复期内逐渐扩大。
Extinction events usually disrupt palaeobiogeographical patterns, but there have been few detailed studies of the Early Silurian survival–recovery period after the Late Ordovician mass extinction. This paper summarizes and revises published information on the recovery of Early and Late Rhuddanian brachiopod faunas. The global dataset consists of 137 occurrences, 72 genera, and 13 localities of Early Rhuddanian (survival interval), and 271 occurrences, 91 genera, and 26 localities of the Late Rhuddanian (early recovery interval). The data are analyzed using Cluster Analysis, Nonmetric Multidimensional Scaling, and Minimum Spanning Tree using Yule's Y coefficient and the Raup–Crick coefficient (probabilistic index of similarity). The results display palaeolatitudinal distribution patterns for brachiopods during their survival and recovery. Frequency analysis of the data indicates that cosmopolitan taxa before the mass extinction decreased in their post-extinction distribution. The survivors were mostly confined to one palaeoplate or even one locality in the survival interval, but expanded progressively in the subsequent recovery period.
