一个突出的床，包含腕足动物和外生苔藓虫，广泛分布于马耳他群岛，与珊瑚藻红石生物礁有关。该层位在上珊瑚系灰岩组底部提供了有用的地层标志层位。已检查了在马耳他和戈佐地区从床上采集的样本，并研究了其中所含的生物数据。通过对苔藓虫生长形式的分布分析，可以识别出四种组合，分别以蜂窝状、脉管状、结壳状、蜂窝状和脉管状苔藓虫生长形式为主。我们还检查了样本中腕足动物的形态变化和分布，并将其与先前获得的苔藓虫生长形式分布进行了比较。四种常见的腕足动物Terebratula Terebratula， Aphelesia bipartita， argyrocaacf的古生态学解释。cordataandMegathiris decollata，部分是基于当今腕足动物生态学，但主要是基于苔藓虫获得的信息。本文还介绍了其他几种常见无脊椎动物属的古生态学解释，这些解释也是基于苔藓虫的生长形式分布。
A prominent bed, containing brachiopods and ectoproct bryozoans, is widely distributed within the Maltese Islands, being associated with a coralline algal rhodolite bioherm. This bed provides a useful stratigraphic marker horizon at the base of the Upper Coralline Limestone Formation.Samples taken from the bed at localities in Malta and Gozo have been examined and their contained biodata studied. Distribution analysis of the bryozoan growth-forms present has permitted recognition of four assemblages, dominated by cellariform, vinculariiform, encrusters, and cellariform and vinculariiform bryozoan growth-forms, respectively. Morphological variations and distributions of brachiopods contained within the samples were also examined and these were compared with the bryozoan growth-form distributions previously obtained. An interpretation of the palaeoecology of the four common brachiopod species,Terebratula terebratula, Aphelesia bipartita, Argyrothecacf.cordataandMegathiris decollata, is offered partly on the basis of present-day brachiopod ecology but mainly on the basis of information gained for the bryozoans. Interpretations of the palaeoecology of several other common invertebrate genera, also based on the bryozoan growth-form distributions, are also presented.
