“…This finding represents the oldest such record for ostracods worldwide. It further confirms the Mesozoic affinity of the present assemblage and ecosystem and the establishment of drilling predation in marine environments during the Late Triassic as indicated by other fossil groups (see Klompmaker et al, 2016 for details).…”

“…The oldest indubitable group that includes drillers is reported from the Valanginian, Early Cretaceous (Kaim, 2004). Triassic occurrences of drill holes are rare, with only unquestionable occur-rences in the Carnian and Norian (see summary and discussion in Klompmaker et al, 2016). The present report is a new addition to the Triassic record of drill holes and the very first known clue of Triassic drilling activity on micro-organisms.…”

“…There are several possible origins for the observed drill hole. We exclude the hypothesis of organisms seeking for domicile (domichnia) because the boreholes left by such activities should rather be cylindrical, complete with multiple drill holes (Klompmaker et al, 2016). Boring organisms in hard substrates are also not favoured, as they should leave cylindrical and complete boreholes, which may penetrate the shell at an oblique angle.…”

“…Boring organisms in hard substrates are also not favoured, as they should leave cylindrical and complete boreholes, which may penetrate the shell at an oblique angle. Oichnus paraboloides Bromley, 1981, might also be of parasitic origin, but in this scenario multiple holes of small size perpendicular to the surface should be observed (Klompmaker et al, 2016). Ostracods are known as hosts of parasites in recent environments as well as in the fossil record, for other crustaceans (Recent: Vannier and Abe, 1993), ciliates (Early Triassic: Weitschat and Guhl, 1994) or Pentastomida (Silurian: Siveter et al, 2015).…”

“…Drill holes were categorized as predatory using the following criteria: morphology, single perforations, penetration from the exterior, penetration axis perpendicular to the shell surface, holes positioned non‐randomly on the shell (stereotypy) and a lack of widely‐ranging sizes (Baumiller ; Kowalewski ; Harper ; Kelley & Hansen ; Daley ; Klompmaker et al . ).…”

A small yet occasional meal: predatory drill holes in Paleocene ostracods from Argentina and methods to infer predation intensity

Ostracods are common yet understudied prey item in the fossil record. We document drill holes in Paleocene (Danian) ostracods from central Argentina using 9025 specimens representing 66 species. While the percentage of drilled specimens at assemblage-level is only 2.3%, considerable variation exists within species (0.3-25%), suggesting prey preference by the drillers. This preference is not determined by abundance because no significant correlation is found between species abundance and drilling percentages. Seven methods were used, some of which are new, to quantify drilling percentages for the abundant and commonly drilled Togoina argentinensis. The resulting range, from 9.9% to 14.6%, suggests that drilling percentages are fairly insensitive to the method used, implying that comparisons across studies are possible. This information, combined with data from the literature, suggests the Cretaceous-Palaeogene mass extinction may have had a limited effect on drilling intensity in ostracods. The cylindrical (Oichnus simplex) and parabolic (O. paraboloides) drill holes from Argentina may have been caused primarily by naticid and possibly muricid gastropods. Two oval drill holes (O. ovalis) are morphologically similar to octopod drill holes, but their small size, the fact that extant octopods are not known to drill ostracods and the absence of such holes in co-occurring gastropods, preclude ascription to a predator clade. Drill holes are located preferentially in the median and dorsal regions, where most soft tissue, including the adductor muscle, is located. Drilled specimens are statistically taller than non-drilled specimens for T. argentinensis and larger predators selected larger ostracods. The drilling percentage does not significantly differ in ornamented ostracods.
