An escallop is the shell of a bivalve mollusc; it is also called a “scallop”, “cockle” or “cockleshell”. The escallop is an ancient charge, found in the arms of Dacre c.1282 [ANA2 351]; it was used as a pilgrim’s badge in medieval times, as it was the symbol of St. James, patron of pilgrims. The escallop has its hinge to chief by default.
