Sinusichnus Gibert, 1996

Diagnosis (emended): Horizontal, branched galleries with sinusoidal elements and off-branches preferably occurring on their convex side, partly resulting in the development of a net-like pattern. Burrow cross-section varies from cylindrical to flat-elliptical and subangular, burrow margin is smooth or ornamented with scratches, and burrow fill may consist of vertical spreiten.
