“…Here, we introduce the spatial point pattern analysis of traces (SPPAT), an approach for visualizing and quantifying the distribution of predation traces on shelled invertebrate prey, which includes improved collection of spatial information inherent to drillhole location, improved visualization of spatial trends, and distance-based statistics for hypothesis testing (see also Clapham et al [2003], Mitchell and Butterfield [2018], and Mitchell et al [2019] for examples that use a similar spatially explicit approach to describe the distribution of well-preserved Ediacaran fossils). We illustrate the SPPAT approach through case studies on museum samples of the Plio-Pleistocene venerid bivalve Lirophora latilirata (Conrad, 1841) from the Atlantic coastal plain of the United States, which has been previously used in studies on drilling predation (Hattori et al 2014; Klompmaker and Kelley 2015); drilling data from laboratory-based feeding trials of the tropical eastern Pacific naticid Notocochlis unifasciata (Lamarck, 1822) preying upon the venerid bivalve Iliochione subrugosa (W. Wood, 1828); and modern beach-collected samples of I. subrugosa from Central America. The SPPAT approach provides tools for visualizing distribution patterns of predation traces on shelled invertebrate prey that could not have been retrieved from current methods and uses distance-based functions to quantify those patterns.…”

Site-selectivity analysis of drilling predation traces may provide useful behavioral information concerning a predator interacting with its prey. However, traditional approaches exclude some spatial information (i.e., oversimplified trace position) and are dependent on the scale of analysis (e.g., arbitrary grid system used to divide the prey skeleton into sectors). Here we introduce the spatial point pattern analysis of traces (SPPAT), an approach for visualizing and quantifying the distribution of traces on shelled invertebrate prey, which includes improved collection of spatial information inherent to drillhole location (morphometric-based estimation), improved visualization of spatial trends (kernel density and hotspot mapping), and distance-based statistics for hypothesis testing (K-, L-, and pair correlation functions). We illustrate the SPPAT approach through case studies of fossil samples, modern beach-collected samples, and laboratory feeding trials of naticid gastropod predation on bivalve prey. Overall results show that kernel density and hotspot maps enable visualization of subtle variations in regions of the shell with higher density of predation traces, which can be combined with the maximum clustering distance metric to generate hypotheses on predatory behavior and anti-predatory responses of prey across time and geographic space. Distance-based statistics also capture the major features in the distribution of traces across the prey skeleton, including aggregated and segregated clusters, likely associated with different combinations of two modes of drilling predation, edge and wall drilling. The SPPAT approach is transferable to other paleoecologic and taphonomic data such as encrustation and bioerosion, allowing for standardized investigation of a wide range of biotic interactions.

Using bivalves from Pleistocene unlithified sediments, Hattori et al (2014) observed no significant differences in several predation estimates obtained by trained novice collectors versus veteran collectors.…”

“…If the size fraction considered for the study happens to be the preferred size class, observed drilling percentage may be unrealistically inflated; the reverse can occur when the preferred size class is missed by sieving. Nevertheless, only a handful of studies have examined the effects of size filtering on measured drilling intensities in detail (Chattopadhyay et al, 2016;Hattori et al, 2014;Hausmann et al, 2018;Kowalewski and Hoffmeister, 2003;Ottens et al, 2012;Visaggi and Kelley, 2015).…”

The fossil record is the primary source of data used to study predator-prey interactions in deep time and to evaluate key questions regarding the evolutionary and ecological importance of predation. Here, we review the types of paleontological data used to infer predation in the marine fossil record, discuss strengths and limitations of paleontological lines of evidence used to recognize and evaluate predatory activity, assess the influence of environmental gradients on predation patterns, and review fossil evidence for predator behavior and prey defense. We assembled a predation database from the literature that documents a steady increase in the number of papers on predation since the 1960s. These studies have become increasingly quantitative and have expanded in focus from reporting cases of predation documented by fossils to using the fossil record of predation to test ecological and evolutionary hypotheses. The data on the fossil record of predation amassed so far in the literature primarily come from trace fossils, mostly drill holes and, to a lesser extent, repair scars, derived predominantly from the Cenozoic of Europe and North America. Mollusks are the clade most often studied as prey and inferred predators. We discuss how to distinguish biotic from abiotic damage and predatory from parasitic traces, and how to recognize failed predation. Our data show that identifying the predator is easiest when predator and prey are preserved in the act of predation or when predators were fossilized with their gut contents preserved. However, determining the culprits responsible for bite traces, drill holes, and other types of predation traces can be more problematic.Taphonomic and other factors can distort patterns of predation, but their potential effects can be minimized by careful study design. With the correct identification and quantification of fossilized traces of predation, ecological trends in predator-prey interactions may be discerned along environmental gradients in water depth, habitat, and oxygen and nutrient availability.However, so far, these trends have not been explored adequately for the fossil record.

“…The relative ease with which quantitative data can be extracted from drilled prey items has made them very popular targets for research, requiring little or no sophisticated equipment and relatively little prior training (Hattori et al . ). As a result in the last 30 years there have been a large number of published studies, both in the peer‐reviewed literature and as conference contributions.…”

Biological interactions between organisms have long been believed to be very important in structuring communities and, when scaled up over geological time, in the evolution of organisms. Investigations of palaeontological evidence for predator–prey interactions have been popular pursuits, and a number of attractive hypotheses have been proposed which link increased predation pressure with a wide range of morphological and ecological changes which are apparent over the course of the Phanerozoic. In particular studies of fossil drill holes and repair scars in shelly prey have been common targets for research. However, the nature of some of our data has been rather anecdotal and restricted in range. Perhaps we should be more concerned that we are not picking up the true range of natural variability. This paper aims to highlight the sources of variability in our data and, going forward, to urge the collection of quantitative data from many more samples and (palaeo)environmental settings in order that we might properly be able to separate the intrinsic natural variability in our data from robust temporal or spatial trends.
