Linckichnus Schlirf , 2006

Macroboring; substrate xylic; tracemaker invertebrate

Diagnosis: Smooth, test-tube shaped, unbranched, slightly kink-bent, cylindrical structures, with circular openings and hemispherical terminations, dominantly perpendicular to the grain of the woody substrate and parallel to each other. Fill massive.

Teredolites as described by Kelly & Bromley (1984) differs from the proposed new ichnogenus in having a clavate shape. Linckichnus n. ig., by contrast, is cylindrical and occurs in poorly lignified plant substrate. 

Category of architectural design: 2.59. Cylindrical vertical to oblique borings.

Unbranched, cylindrical.
