盐度控制的底栖大型无脊椎动物协会是典型的许多中生代边缘海洋环境。它们可以通过非生物标准（例如，根据生物标准（动物群组成、多样性、贝壳形态、大小-频率直方图、埋藏特征、相关的微型动物群和微植物群）和贝壳的同位素地球化学特征，确定了1998年至2000年期间的贝壳数量和分布（环境背景、特定自生矿物）。虽然盐度控制的协会必须在欧洲德国三叠纪广泛存在，但对其生态学知之甚少。它们似乎是由双壳类的Unionites和腕足类的Lingula主导的。在侏罗纪，半咸水组合的特征是双壳类，特别是新齿类，corbulids，mytilis，bakevelliids，isognomonids和牡蛎。在白垩纪，此外，corbiculid双壳类和腹足类变得越来越丰富。盐度控制的底栖大型无脊椎动物协会可用于重建古代环境的盐度状况，但应强调综合沉积学和生态学方法，因为盐度很少是影响动物群组成和多样性的唯一参数。虽然盐度控制的底栖动物协会的物种组成的变化明显，随着时间的推移，组成的形态仍然令人惊讶的是恒定的整个中生代和最近，底栖动物群的边缘海洋高应力环境内的保守进化的证据。盐度、底栖生物组合、古生态学、中生代。
Salinity-controlled benthic macroinvertebrate associations are typical of many Mesozoic marginally marine environments. They can be recognized by abiotic criteria (e.g., environmental setting, specific autigenic minerals), by biotic criteria (faunal composition, diversity, shell morphology, size-frequency histograms, taphonomic features, associated micro fauna and microflora), and by isotope geochemistry of shells. Although salinity-controlled associations must have been widespread in the European German Triassic, very little is known about their ecology. They appear to have been dominated by the bivalve Unionites and the brachiopod Lingula. In the Jurassic, brackish-water associations are characterized by bivalves, in particular neomiodontids, corbulids, mytilids, bakevelliids, isognomonids, and oysters. In the Cretaceous, in addition, corbiculid bivalves and gastropods become increasingly abundant. Salinity-controlled benthic macroinvertebrate associations can be used to reconstruct salinity regimes of ancient environments, but emphasis should be placed on an integrated sedimentological and ecological approach, as salinity is rarely the only parameter influencing faunal composition and diversity. Although the species composition of salinity-controlled benthic associations changes distinctly through time, the composition of morphotypes remains surprisingly constant throughout the Mesozoic and up to the Recent, evidence of a conservative evolution of benthic faunas within marginal marine high-stress environments. □Salinity, benthic associations, palaeoecology, Mesozoic.
