Coordinates for traces of predation in Meoma tests from San Salvador Island

Here, we examine interactions between the spatangoid echinoid Meoma ventricosa and the drilling predatory gastropod Cassis tuberosa from a shallow tropical marine habitat (San Salvador Island, Bahamas) to assess the impact of drilling predation on the fossilization potential of echinoids, estimate drilling frequency, characterize drill hole morphology, and evaluate size and site selectivity of predators. Cassid gastropods commonly attack sea urchins today, creating a distinct circular hole in the urchin exoskeleton using the radula, often in conjunction with the application of acid secreted by the accessory boring organ to weaken the test, which can result in a serrated hole. In some cases, radula rasping traces were also present around the hole. Data include size measurements of M. ventricosa tests and drill holes on the test made by C. tuberosa. In addition, two-dimensional landmark co-ordinates are provided to determine the location of the drill hole on the test.本研究针对巴哈马圣萨尔瓦多岛热带浅海生境中的两类生物展开相互作用分析：心形目海胆类（spatangoid echinoid）巨腹海胆（Meoma ventricosa）与钻孔捕食性腹足类瘤盔螺（Cassis tuberosa）。研究目标包括评估钻孔捕食对海胆类化石保存潜力的影响、估算钻孔频率、刻画钻孔形态特征，以及探究捕食者的体型与栖息位点选择性。 现生盔螺科腹足类普遍会捕食海胆：它们会借助齿舌在海胆外骨骼上形成特征性圆形钻孔，同时常配合附属钻孔器官分泌的酸性物质软化海胆壳（test），最终可形成边缘呈锯齿状的钻孔。部分钻孔的周围还可见齿舌刮擦留下的痕迹。 本数据集包含巨腹海胆（Meoma ventricosa）的海胆壳（test）尺寸测量数据，以及瘤盔螺（Cassis tuberosa）在其壳上形成的钻孔的相关测量数据。 此外，数据集还提供了二维地标坐标，用于精准确定钻孔在海胆壳上的具体位置。
