Specimens are disorganized, sand-filled, exichnial burrow casts in mudstone. Gently curved and nearly horizontal to bedding, the burrows show ovoid to circular cross-sections. Both single and grouped burrows are present. Grouped burrows lie subparallel to each other, as many as three in a row, having a common entry point. Both burrow setsand single burrows may intersect others. Thin sections highlight the meniscate backfills.
