Buatois et al., 2017:
Umbichnus Martinell et al., 1999 is an unusual pouch-shaped boring cut into the hinge plates of both valves of bivalves. The authors, though, cannot dismiss the possibility that it is a dissolution feature and not a boring (Martinell et al., 1999).
Martinell et al, 1999:
Diagnosis: Sack-shaped boring having a single aperture, etched into both valves of bivalves in the hinge plates beneath the umbones.
