Mercanaria Clams are an extinct genus of marine bivalve mollusks that lived during the Miocene epoch, approximately 20 million years ago. They belong to the family Mercanariidae, a group of fossil clams primarily found in the Middle to Late Miocene sediments of the Florida platform. These fossil clams are easily recognized by their distinctive shell shape and the presence of three to four cardinal teeth on each valve.
What makes Mercanaria fossil clams particularly remarkable is their exceptional preservation. Many specimens display impressions of the animal’s soft body parts, including the mantle and siphon, providing scientists with rare insights into the anatomy and behavior of this ancient species.
These fossil clams are abundant in the Florida Keys, where they occur in a variety of fossil-bearing formations such as limestone and dolostone. Mercanaria fossils are often found alongside other marine organisms, including sharks, rays, and sea turtles, offering valuable information about the Miocene marine ecosystems and the environmental conditions in which these bivalves thrived.
