Size refugia from predation through time: A case-study of two Middle Devonian brachiopod genera

Predation scars offer insight into ancient predator–prey relationships and evolutionary processes. One approach to studying predation in fossils is through repair scars, which indicate a failed attempt at predation as the prey survives the attack and repairs its shell. A change in repair frequency is ambiguous as it may indicate either a change in the number of attacks on the prey or a change in the success of the predator. Size refugia, the...
