Talpina lizardensis (Lees et Thomas, 1918)

Fine tubular burrows 0.1 to 0.25 mm. in diameter penetrating the shells of brachiopods, especially those of Spirifer pettaensis Weller. The burrows are circular to subcircular in cross section and they ramify the shell structure in all directions. In parts of some shells they are sufficiently numerous to cause partial disin tegration in much the same way that modern Cliona destroys the shells of oysters and other bivalves.
