Abstract 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 size of the prey at which the predator will n...

Abstract One of the primary differences between paleoecological and modern ecological research is the added dimension of deep geological time. The temporal dimension of paleoecological research can create added difficulties when determining the appropriate spatiotemporal sampling procedures required for any particular study. Previous paleocommunity studies have found that the spatial extent of sampling can have a grave impact on the multivariate analytical results. Here, we expand spatially on t...
