Virginia Clams

Chesapecten Jeffersonius is the state fossil of the U.S. state of Virginia. It is the fossilized form of an extinct scallop, which lived in the early Pliocene epoch between four and five million years ago on Virginia's coastal plain. In 1687, Martin Lister published a drawing of the fossil and then it became the first fossil to be described from North America.

In 1824, geologist John Finch gathered a large collection of mollusk fossils, including Chesapecten jeffersonius, from the vicinity of Yorktown, Virginia, and gave them to scientists at the Academy of Natural Sciences of Philadelphia (ANSP).

In 1993, the General Assembly adopted the Chesapecten jeffersonius as the state fossil. This fossil was the first discovered in North America. It was named for Thomas Jefferson because of his interest in natural history. The fossil also celebrates the Chesapeake Bay, the largest estuary in the world.
