Genus
Trypanites Mägdefrau, 1932
Taxon description
Wisshak et al., 2019a
Macroboring; substrate calcareous; tracemaker invertebrate
Knaust et al., 2023a
Diagnosis. Single-entrance, cylindrical, unbranched borings in hard substrates, having a circular cross-section throughout length. The axes of the borings may be straight, curved or irregular (after Bromley & D’Alessandro 1987; modified by Neumann et al. 2008).
Buatois et al., 2017
Category of architectural design: 2.59. Cylindrical vertical to oblique borings.
Knaust, 2012a
Unbranched, cylindrical
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.
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.
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.
