Squamichnus Leszczyński, 2003

Diagnosis: Bedding-parallel to slightly oblique, elongate, rarely branched, unlined burrows showing a segmented, scale-like (squamate) to homogeneous fill in planar view, marked in the vertical section as bedding parallel to oblique dark-coloured streaks or as a structure resembling cross-section of a rolled cake.

However, the ‘scales’ in Squamichnus differ in outline and less regular arrangement from the meniscate segments in all these trace fossils
