Mercanaria Clams are extinct marine bivalve mollusks from the family Mercanariidae, living during the Miocene epoch, around 20 million years ago. Known for their distinctive shell shape and three to four cardinal teeth on each valve, these fossil clams are highly prized by collectors and paleontology enthusiasts.

What sets Mercanaria apart is the rare preservation of soft body impressions, including the mantle and siphon, offering unique insights into the anatomy and behavior of this ancient species. Fossils are commonly found in the Florida Keys, within limestone and dolostone formations, often alongside other Miocene marine life such as sharks, rays, and sea turtles, revealing the richness of their ancient marine ecosystem.

These fossils combine scientific significance and visual appeal, making them ideal for fossil collections, museum displays, and educational exhibits. Their well-preserved shells and rare soft tissue impressions make Mercanaria Clams a standout among Miocene bivalves.
