Pilichnus Uchman, 1999
Taxon description
Mikuláš et al., 2004
Pilichnus isp. Description: A system of horizontal, straight, curved to irregularly winding, branched strings without wall lining, preserved in full relief on parting surfaces. The strings are 0.3–0.6 mm wide. They are filled with a darker argillaceous substance. Their dichotomous, Y-shaped branches are characteristic. Remarks: Systems of these shapes have usually been interpreted as fragments of the essentially radial, regular trace fossil Chondrites. However, as these systems represent the deep tier, there is no reason to assume that the traces are incomplete. We therefore accept the systematic solution proposed by Uchman (1999), who established a new ichnogenus Pilichnus for irregular Chondrites-like traces.
