Teredina is an extinct genus of fossil bivalve mollusks that lived from the Late Cretaceous to the late Pliocene in Asia, Europe, and North America.[1]

Teredina shells consist of 2 short, hooked valves with a pair of furrows and each valve with transverse ridges.[2] The overall body was long and clud-shaped. Teredina used the ridges on each valve to bore into drift wood 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.[2]Petrified drift wood with Teridina burrows can be found in the Cretaceous rocks of Vancouver Island.[2]
