Taxon description

Fan, R. et al., 2021

Horizontal, straight to winding, cylindrical burrows with numerous relatively small pellets 0.3–0.5 mm in diameter. The burrow is 2–3 mm wide. Cross-cutting relationship between individuals is common, locally showing dense overlapping. Preserved as full relief in thin-bedded limestone of the Sandbian.
