Taxon description

Wisshak et al., 2019a

Predation; substrate calcareous; tracemaker invertebrate

Diagnosis. – Serrated Mandibulichnus. Breakages consist of straight segments of variable length which join at variable angles, depicting somewhat variable morphologies tending to a V-shaped or asymmetrical W-shaped pattern (serrated pattern). The first order path of the trace is more or less straight, yet sometimes is slightly arcuate.

Description. – Mandibulichnus present on our material shows a marked, serrated outline with a high variable segment length (approximately 0.7 mm to 2.8 mm on the short side and 0.8 mm to 8 mm on the long side of the V-segments) and angle (between 55° and 127°). The largest and most complex specimen is approximately 18 mm in overall length and 4.3 mm “deep”.
