This trilobite of the speices Elrathia kingi shows a very clear bite mark.
Bitemaks are relative common documented on Elrathia kingi. But the most fossil trilobite injury’s are more ore lees regenerated or are in the beginning of the healing progress. However the injury of this trilobite shows no traces of healing or wound sealing. It is most certain that this pathology caused the death of this specimen. Anyway the poor trilobite must managed to escape his predator before death. This also explains why healed trilobite injury's much more common than the deadly ones. A predetor would eat the trilobite in whole or in peaces and we would find in the best case a few disarticulated fragments of the carapace on the scene. In most cases of predatory pathology’s on Elrathia are suspect to be causes by Anomalocaris.
Anomalocaris and other Anomalocarididae are most likely feared predetors of the trilobites till the devonian age. Whenn the rising of the fishes beginnes and the slow extinction of the trilobites start.
