Taxon description

Lima & Netto, 2012

Subcylindrical to flattened burrows of slightly curved trajectory, whose extremities plunge into the substrate. Burrow margins lined and ornamented by longitudinal parallel grooves, whose degree of preservation varies among the specimens. Burrow fill is composed of sediment identical to that of the surrounding matrix. Average burrow diameter is 4.79 mm, with a minimum diameter of 1.71 mm and a maximum diameter of 6.28 mm. Preservation in positive hyporelief.

Mikuláš et al., 2002a

Straight, horizontal, secondarily flattened, unbranched tunnel with wall lining, 11–12 mm wide and 35 mm long. Wall surface is covered with straight, regular rounded ridges (6 ridges in trace width). The tunnel is preserved as full relief in calcareous siltstone.

Very thinly lined, longitudianally striated burrows, continuous parallel striae.
