Abstract of ref. 432:
During the Late Oxfordian and Middle Kimmeridgian (Late Jurassic), small patch  reefs were formed at numerous localities in northern Germany. The richly structured neritic sea was characterized by seasonally varying environmental factors, such as water movement and illumination as ecological requisites, and sedimentological conditions and bioerosion as ecological addends. These factors evidently affect the faunas. Thus, a palaeontological facies interpretation is possible according to qualitative and quantitative criteria supported by sedimentological results. Twenty six species of reef corals are described in detail and arranged in various guilds (builders, bafflers, binders, dwellers) on the basis of the impact of growth forms on the skeletal frame. However, intraspecific variation of guild membership may occur due to different reefal architecture. The most important synecological parameters, dominance and diversity, are calculated for all localities. Thamnasteria concinna (GOLDFUSS) which can tolerate partial mortality well is the dominant species in various environments, thus showing ubiquitous characteristics. The diversities of the associations examined are generally low and strongly vary within comparable facies. This fact proves the oscillation of important environmental factors. Despite the ecological preferences of some taxa, the distribution of reef corals seems to be mostly random, at least in more favourable environments.
