Recognizing biotic breakage of the hard clam, Mercenaria mercenaria caused by the stone crab, Menippe mercenaria: An experimental taphonomic approach

►This paper investigates whether durophagous predators produce distinct traces. ►Biotic breakage patterns were assessed using predation experiments. ►Abiotic breakage was assessed using taphonomic experiments. ►Biotically produced macro- and microstructural fracture patterns are distinctive.
