TitleFossil predation: did some clavilithine fasciolariid gastropods employ valve-wedging to feed on bivalves?

AbstractSeveral gastropods, including members of the
Busyconinae, wedge or chip bivalve prey by inserting the
outer lip between the valves. This habit, which is associated
with an abapically downwardly convex outer lip, often results
in breakage and subsequent repair of the lip. I tested the
hypothesis that convex-lipped clavilithines from the Eocene
of France and the Neogene of Indonesia had higher frequencies
of repair than their straight-lipped counterparts. Although
this prediction was verified, frequencies of repair are low (0
to 0.19) compared to those of busyconines, indicating either
that prey bivalves were small or that the predators are smaller
than most busyconines.
