Teredina is an extinct genus of fossil bivalve mollusc that lived from the Late Cretaceous to the late Pliocene in Asia, Europe, and North America.^[2]

Teredina shells consist of 2 short, hooked valves with a pair of furrows and each valve with transverse ridges.^[3] The overall body was long and clud-shaped. Teredina used the ridges on each valve to bore into driftwood by rocking back and forth; its long body shape allowed for large intestines for it to carry bacteria capable of breaking down the cellulose in the wood.^[3] Petrified drift wood with Teridina burrows can be found in the Cretaceous rocks of Vancouver Island.^[3]
