Reduced Competition and Altered Feeding Behavior Among Marine Snails After a Mass Extinction
TLDR
Analysis of predation traces produced by shell-drilling muricid snails on bivalve prey reveals that species interactions were substantially different before and after a Plio-Pleistocene mass extinction in the western Atlantic.

Reconstructing early 17th century estuarine drought conditions from Jamestown oysters
TLDR
Comparing oxygen isotope data from these 17th century oyster shells with modern shells is compared to quantify and contrast estuarine salinity, season of oyster collection, and shell provenance during Jamestown colonization (1609–1616) and the 21st century.

Shell Bead Sourcing: A Comparison of Two Techniques on Olivella biplicata Shells and Beads from Western North America
We compare two methods for tracking the geographic source of Olivella biplicata shell beads along the California and Oregon Pacific coast; bulk element composition by inductively coupled plasma-mass…

Systematic Revision of the Genus Eupleura H. and A. Adams, 1853 (Gastropoda: Muricidae) in the Neogene to Recent of Tropical America
TLDR
The systematics of the Neogene to Recent genus Eupleura of tropical America are revised, with descriptions of four new species and two recent taxa resurrected, increasing the standing diversity of EupleURA in the eastern Pacific to seven species.
Measuring relative abundance in fossil and living assemblages
TLDR
The purpose here is to identify a previously unrecognized problem that could lead to incorrect interpretation of observed patterns of abundance and to evaluate biases related to preservation and sampling.

Reconstructing Carbon Sources in a Dynamic Estuarine Ecosystem using Oyster Amino Acid &dgr;13C Values from Shell and Tissue
TLDR
The results presented here demonstrate that compound-specific amino acid analysis of carbon isotopes is a useful tool in the analysis and interpretation of biomineral organic materials.

Influence of alternative shell‐drilling behaviours on attack duration of the predatory snail, Chicoreus dilectus
TLDR
It is suggested that owing to the shorter length of time required to kill prey, the edge-drilling behaviour may be selectively advantageous in environments where enemies are abundant, especially competitors that might attempt to steal prey.

A note on edge drilling predation by naticid gastropods
TLDR
The first laboratory studies of the predatory behaviours of Polinices lacteus are reported, which include the first direct observation of edge drilling by an Atlantic naticid.
