“…Assemblage-level DI is analyzed separately for gastropods and bivalves and is calculated as the percentage of drilled individuals. Because DI may vary with prey size (Vermeij, 1987; Allmon et al, 1990; Paul et al, 2013; Sarkar et al, 2016), DI is measured for different size classes within the turritelline species. Previous workers, including Paul et al (2013) and Sarkar et al (2016), subdivided turritellines into two size classes with a cut-off at 4 cm shell height.…”

“…Morphological characters such as shell ornamentation, shell thickness, and shell slenderness of gastropods, which resulted from evolutionary adaptation, are arguably the resistant characters against predation during the Cenozoic (Vermeij et al, 1980; Signor, 1985; Paul et al, 2013; Sarkar et al, 2016). Ornamentation hinders the drilling process, and thick shells increase the drilling time; thus, more cost is involved, which makes the prey unprofitable.…”

“…The Mesozoic phase was marked by a lull with rare, facultative drilling events (Fürsich and Jablonski, 1984; but see Vermeij, 1977, 1987). The Cenozoic phase led to the high drilling intensities (DIs) on molluscan prey (Carriker and Yochelson, 1968; Kelley and Hansen, 1993, 1996, 2006), which continue to be observed in modern marine environments, on a variety of taxa (Dudley and Vermeij, 1978; Boucher, 1986; Vermeij, 1987; Mondal et al, 2010; Paul et al, 2013; Chattopadhyay et al, 2014; Das et al, 2014; Klompmaker et al, 2015; Pahari et al, 2016; Saha et al, 2016; Sarkar et al, 2016; Mondal et al, 2019a, b; among others).…”

“…Predatory drill holes in marine shells provide information about ecological interaction and help make predation-related hypotheses (e.g., escalation) testable by applying detailed statistical analyses. The study of drilling predation in extant and extinct taxa, therefore, forms the focus of many research papers (Vermeij, 1977, 1987; Kelley and Hansen, 1993; Harper, 1994; Kardon, 1998; Dietl and Kelley, 2002, 2006; Kowalewski, 2002; Mondal et al, 2010, 2017, 2019a, b; Bardhan et al, 2012, 2014; Das et al, 2014; Mallick et al, 2014; Pahari et al, 2016; Sarkar et al, 2016; Anderson et al, 2017; Klompmaker et al, 2017, 2019; among others).…”

We document and quantify one of the oldest predator–prey interactions between naticid gastropods and molluscan prey, on the basis of drill holes in shells, from the Late Jurassic (Oxfordian) beds of Kutch, western India. Previously, many workers recorded naticid-like drill holes on prey taxa from the Triassic and the Jurassic, but in the absence of associated naticid body fossils, they remained equivocal. The present gastropod community is dominated by turritellines (98% of the sample) that form the turritelline-dominated assemblage, and the naticid drilling predation is restricted almost entirely to turritellines among gastropods. Confamilial naticid predation takes place occasionally. Within the bivalve community, corbulids and nuculids are most abundant and are drilled more often than other taxa. These observations indicate that prey selection was opportunistic and based solely on availability. Drilling intensities at both assemblage and lower taxon levels are low. Behavioral stereotypy of naticid predation in some cases is moderately high. Turritellines are often the preferred prey of naticid gastropods since the late Early Cretaceous. These two groups form a recurrent association reflecting prey–predator interaction. Here we suggest that both turritellines and naticids evolved during the Jurassic, and the prey–predator interaction between them was established shortly thereafter. Among bivalves, corbulids also became important prey of naticids in the same spatiotemporal framework. Corbulids are older than naticids and first appeared during the Middle Jurassic. After their first encounter with naticids, corbulids evolved conchiolin layers within the valves to resist predation.
