ABSTRACT
We discuss a previously undescribed shell morphology in unionid mussels from three archaeological sites in western Mississippi. Similar shell features are observed across multiple genera, indicating a possible phenotypic response to an as-of-yet unidentified environmental factor. Targeted research of this phenomenon may lead to applications in paleohydrology and environmental archaeology.
