Description(s)
Taylor & Wilson, 2003:
Remark: Cylindrical, unbranched boring; length up to 50 times width. Some Ordovician examples described by Kobluk and Nemcsok (1982) contain scolecodonts suggesting that the borings were made by polychaete worms.
Blissett & Pickerill, 2007:
Diagnosis– (Modified after Bromley & D’Alessandro, 1987, p. 403.) Single entrance, cylindrical or sub-cylindrical, unbranched boring in lithic or biogenic substrates having circular cross-section throughout length. The axes of the boring may be straight, curved or irregular.
Bhattacharaya & Banerjee, 2014:
Diagnosis.—Included in Trypanites are simple unbranched vertical to sinuous borings with a single opening to the surface; with or without a flared entrance. Circular in cross section; generally isodiametric throughout the entire length but may terminate in a small cupulate chamber.
