Explore how mollusk shells reveal Florida Bay’s past and present environments.

This scholarly overview examines how shell fossils in bay sediments tell a story of changing water depth, salinity, and landward movement. Through field observations and core samples, the work reconstructs shifts between Everglades influence and marine intrusions, using taxa such as Parastarte, Hydrobia, Cerithidea, and Anomalocardia to read the history written in the sediment.

The book combines detailed descriptions of sediment cores with faunal analyses to explain how environments evolved over time. It discusses how storms move shells, the concept of various biofacies, and how sorting of shells after death affects the fossils we find today. It also touches on mollusk biology, including precocious maturity in several species and what shell remains can say about living communities long gone.

How shell assemblages map ecological zones, from Everglades-influenced to Playa-like conditions
What core samples reveal about past sea levels, salinity, and inundation
How postmortem shell movement and storms shape the fossil record
Biological notes on mollusk development and its relevance to taxonomy

Ideal for readers of paleoecology, marine geology, and Florida Bay studies seeking a clear, evidence-based look at how shells bear witness to environmental change.
