与大多数其他海洋无脊椎动物不同，棘皮动物通过其骨骼组织的特异性反应，倾向于识别寄生虫和寄生虫的同体侵染。附着或包埋结构以及修复特征通常反映了痕迹标记的解剖形态，因此可能具有解释价值。在与海胆有关的众多无脊椎动物中，只有少数紧紧附着在宿主的外表面，在骨骼上留下可见的损伤。在这里，我们描述了蚀刻的附件疤痕，几毫米的大小，由一个圆形到近圆形的有机体上的holasteroid海胆Echinocorys perconica（冯Hagenow，1840年）从下马斯特里赫特白垩北方德国的口腔表面。我们比较的痕迹与最近的附着疤痕底栖有孔虫，如Hyrrokkin sarcophaga，因此建议寄生有孔虫作为最可能的痕迹制造商。
In contrast to most other marine invertebrates, echinoderms favor the recognition of a syn vivo infestment of parasites and commensals by the specific response of their skeletal tissues. Attachment or embedment structures, but also repair features commonly mirror the anatomical morphology of the trace maker and may therefore be of interpretive value. Among the numerous groups of invertebrates associated with sea urchins, only a few are tightly attached to the external surface of the host, leaving visible damage on the skeleton. Here, we describe etched attachment scars, a few millimeters in size, produced by a circular to subcircular organism on the oral surface of the holasteroid echinoid Echinocorys perconica (von Hagenow, 1840) from the Lower Maastrichtian chalk of northern Germany. We compare the traces with Recent attachment scars produced by benthic foraminifers such as Hyrrokkin sarcophaga and consequently suggest a parasitic foraminifer as the most probable trace maker.
