Mercanaria Clams are extinct marine bivalve mollusks from the family Mercanariidae, dating back approximately 20 million years to the Miocene epoch. These fossil clams are well-known for their distinctive shell shape and three to four cardinal teeth on each valve, making them easily identifiable and highly prized among fossil collectors and paleontology enthusiasts.

What sets Mercanaria apart is the exceptional preservation found in some specimens. In rare cases, the fossils display impressions of soft body parts, including the mantle and siphon, providing a unique glimpse into the anatomy, behavior, and lifestyle of this ancient species. Such preservation is incredibly valuable for scientific research and adds significant display appeal for collections.

These fossils are abundant in the Florida Keys, occurring in a variety of fossil-bearing formations, including limestone and dolostone. Mercanaria Clams are often found alongside other Miocene marine organisms, such as sharks, rays, and sea turtles, offering insights into the diverse marine ecosystems of the Miocene.

Whether for museum displays, educational exhibits, or private collections, Mercanaria Clams combine scientific significance, rarity, and aesthetic appeal. Their well-preserved shells and occasional soft tissue impressions make them a standout example of Miocene marine life, providing both educational value and visual beauty.
