在约克郡、林肯郡、诺福克郡、萨里郡和威尔特郡的Kimmeridge Clay以及多塞特郡Kimmeridge Bay及其附近的悬崖段的11个地层中，都记录到了富含coccolith的薄带，其中coccolith构成了岩石的主要部分。在英格兰南部和东部，似乎至少有9个这样的条带形成了持久的标记。讨论了球石虫的组合，并系统地描述了一些种。
Summary Thin coccolith-rich bands, in which coccoliths make up a major part of the rock, have been recorded at 11 horizons in the Kimmeridge Clay of Yorkshire, Lincolnshire, Norfolk, Surrey and Wiltshire and also in cliff sections at and adjacent to Kimmeridge Bay, Dorset. It seems likely that at least nine of these bands form persistent markers throughout southern and eastern England. The coccolithophorid assemblages are discussed and some species of Stradnerlithus are systematically described.
