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.
