Abstract

The Grammysiidae are an important but little understood family of Paleozoic bivalves. Specimens of Grammysia obliqua (McCoy) from the Stonehouse Formation (Uppermost Silurian), Nova Scotia, permit interpretation of their functional morphology and autecology. Grammysia obliqua was an immobile, semi‐infaunal, filter‐feeding bivalve. It lived fixed by a byssus, with the shell inclined about 40° to the sediment‐water interface. Though incapable of opening the shell, the animal maintained contact with the environment through byssal and dorsal‐posterior gapes. This latter gape was in a peculiar position for a bivalve and required some anatomical adaptation, but it was functionally efficient for the animal's life attitude.
