Summary

[edit]
Description

Turritella terebralis Lamarck, 1799 - fossil snail shell with predatory drill hole from the Miocene of France. (the boring is a little under 4 millimeters in diameter)

The circular hole in the photo is a predatory boring in a Turritella fossil snail shell. Borings are examples of trace fossils - any indirect evidence of ancient life. Other categories of trace fossils include burrows, tracks, trails, footprints, and bitemarks. Traces (also called ichnofossils) record the behavior of ancient organisms. Trace fossils are given scientific names in a similar style as living organisms or body fossils.

Predatory drill holes in shells are known from the latest Precambrian to the Holocene. The beveled boring shown here was made by a naticid gastropod (moon snail).

Classification of host shell: Animalia, Mollusca, Gastropoda, Turritellidae

Stratigraphy: unrecorded/undisclosed unit in the Burdigalian, Lower Miocene

Locality: unrecorded/undisclosed site in France (probably near Bordeaux in southwestern France)
