摘要 英国温洛克地区存在五种常见的三叶虫群落。这些组合的特点是特定属的丰度增加，其分布与岩相和古坡位置的变化有关。类似的关联在世界其他地区的志留纪中也很普遍。不同时代的相似岩相通常包含一般相同的三叶虫组合，因此突出了基于特定水平之上的比较进行相关性的危险。
Summary Five common trilobite associations occur in the British Wenlock. The associations are characterised by increased abundance of particular genera and their distribution is related to changes in lithofacies and position on the palaeoslope. Comparable associations are widespread in the Silurian of other parts of the world. Similar lithofacies of different ages often contain generically identical trilobite assemblages thus highlighting the dangers of basing correlations upon comparisons made above the specific level.
