在这里，我们描述了Conulariids和Holdfast生产者之间的表生生物组合，附着伤痕类似于来自威斯康星州志留纪(泰利钦晚期)Brandon Bridge组的管状表生生物Sphothallus。圆锥虫种群是Waukeha生物群中最丰富的固着生物，由两个种组成：Conularia niagarens Hall，1852和Metaconularia cf.曼尼(Roy，1935)。锥体测试上的附着伤痕提供了一个独特的机会，让我们得以一窥志留纪底栖生物组合的古生态。然而，附着的附生生物的体化石很少，也没有观察到附着在或靠近圆锥标本的身体化石。这项研究评估了螺科和它们神秘的表生生物之间的身份和古生态关系。通过对附着痕迹的大小、频率和分布的统计分析，可以了解它们之间共生关系的本质。我们的结果没有发现任何支持寄生关系的显著支持。然而，不能排除共生论，它是这两个有机体之间关系的另一种解释。
Here we describe an epibiont association between conulariids and holdfast producers, with attachment scars resembling those of the tubular epibiont, Sphenothallus, from the Silurian (late Telychian Series) Brandon Bridge Formation, Wisconsin. The conulariid population represents the most abundant sessile organisms in the Waukesha Biota and consists of two species, Conularia niagarensis Hall, 1852 and Metaconularia cf. manni (Roy, 1935). Attachment scars present on the conulariid test offer a unique glimpse into the paleoecology of this Silurian benthic assemblage. However, body fossils of the attached epibiont arc scarce and have not been observed attached or near conulariid specimens. This study evaluates the identity and paleoecological relationship between the conulariids and their enigmatic epibionts. Statistical analyses of attachment trace size, frequency, and distribution on the conulariid test gives insight to the nature of their symbiotic relationship. Our results did not find any significant support for a parasitic relationship. However, commensalism cannot be ruled out and serves as an alternative explanation for the relationship between these two organisms.
