In an article recently published in the Journal of Archaeological Science, Peacock
and Seltzer discuss freshwater mussel remains from a Middle Archaic site on the Tombigbee
River in Mississippi, southeastern U.S.A. The article concerns conflicting paleoclimatic
information provided by different data sets (trace elements, stable isotopes, shell
size and sculpture). Unfortunately, errors exist in the discussion of stable isotopes.
Because members of the archaeomalacology working group might be interested in the
article, I though it would be useful to point out that the errors have been recognized
and are detailed in an upcoming corrigendum in the JAS, and that they do not affect
the overall conclusions of the article. These errors are the responsibility of the
Peacock, Evan, and Jennifer L. Seltzer 2008 A Comparison of Multiple Proxy Data Sets
for Paleoenvironmental Conditions as Derived from Freshwater Bivalve (Unionid) Shell.
