Abstract

The clavate boring Teredolites Leymerie is produced in wood by teredinid bivalves and occurs at various sites in the Cenozoic of the Antillean region. Most commonly, the enclosing lignic substrate rots away and preservation relies on the calcareous lining, an organic mold of the bioerosive structure. Teredolites longissimus Kelly and Bromley from the (probably Middle) Eocene of the Ceru di Cueba Formation of Curaçao is unusually well preserved and intertwined tubes occur in life associations in a calcareous sandstone matrix. The waterlogged, enclosing wood presumably sank to the seafloor and was buried. As it rotted away, sand slipped into the void and held the T. longissimus tubes in place.
