摘要

在爱沙尼亚Katian(晚奥陶世)，内生圆锥虫与表状珊瑚和叠层孔虫形成共生关系。它们受益于稳定的基质和宿主骨骼提供的额外保护，免受捕食者的侵害。本文首次从苔藓虫中报道了共生舌状体和类似输卵管毛囊的生物闭锁结构。在爱沙尼亚的卡蒂亚，内生舌藻也是表状珊瑚的共生体。苔藓虫是波罗的海卡蒂亚最多样化的内生菌群的宿主。在波罗的海的Katian，珊瑚和层孔虫只容纳了几组内生菌。

Diverse endobiotic symbiont fauna from the late Katian (Late Ordovician) of Estonia

Endobiotic cornulitids formed symbiotic associations with tabulate corals and stromatoporoids in the Katian (Late Ordovician) of Estonia. The cornulitids benefited from a stable substrate and additional protection against predators offered by the skeleton of their hosts. Symbiotic lingulates and Chaetosalpinx -like bioclaustration structures are here reported from bryozoans for the first time. The endobiotic lingulates were also symbionts of tabulate corals in the Katian of Estonia. Bryozoans hosted the most diverse fauna of endobionts in the Katian of Baltica. Corals and stromatoporoids hosted just few groups of endobionts in the Katian of Baltica.
