Meanders irregular and variable in shape, mostly deep, but also shallow, with bell-shaped and, or, horseshoe-shaped segments, but no straight segments or loops. The axes of the meanders are not parallel. Diameter is variable and generally constant within a single specimen (modified from Książkiewicz, 1977).

Buatois et al., 1996

Description: Irregularly meandering, unbranched, smoothsurfaced, horizontal burrows. Meander dimensions are variable. Amplitude of the meanders ranges from 1 to 6 mm.
