Descriptions and remarks
Unbranched, cylindrical.
Category of architectural design: 2.76. Single circular to tear-shaped attachment bioerosion traces.
Diagnosis: Surface marks with oval to slightly ellipsoidal margin terminating on sharp end, with overall teardrop-shape. The margin clearly distinguished by colour of surrounding substrate, which is usually more heavily weathered or eroded, or by fairly deep, wide boring. Marks are smooth or exhibit light ornamentation consisting of discrete, shallow series of eccentric borings on interior.
