Diagnosis. Rod-shaped coprolite, rounded to slightly oval in transverse sections (sometimes with a small concave dorsal depression), displaying a bilateral symmetric pattern of rounded shaped canals. In the symmetry plane, a comparably thick longitudinally furrow (or median canal), cylindrical to claviform in section, is present. Interconnecting lines or fissural spaces between canals or connections between the latter and the median furrow are absent.
