in the Paleobiology Database ''Teredina'' shells consist of 2 short, hooked valves with a pair of furrows and each valve with transverse ridges.Ludvigsen, Rolf & Beard, Graham. 1997. West Coast Fossils: A Guide to the Ancient Life of Vancouver Island. pg. 107 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. Petrified drift wood with ''Teridina'' burrows can be found in the Cretaceous rocks of Vancouver Island.
