Descriptions and remarks
Diagnosis: Predominantly horizontal, unbranched, unlined, elongated tubes, circular or subcircular in cross-section, straight or tortuous, located at the interface of bone and sediment, but penetrating the bone cortical tissue; fill consists of both unconsolidated sediment and bone chips; rough texture of the exposed surface.
Macroboring; substrate osteic; tracemaker invertebrate
Emended diagnosis.—Predominantly horizontal, unbranched, unlined, elongated tubes, circular or subcircular in cross-section, straight or tortuous, located at the interface between bone and sediment, but penetrating the cortical bone tissue and occasionally the trabecular bone tissue; fill consists of both unconsolidated sediment and bone chips; rough texture of the exposed surface (modified from Pirrone and Buatois 2016).
