Spatial Variation in Predation in the Plio-Pleistocene Pinecrest Beds, Florida, USA

We examined six temporally equivalent assemblages distributed across 700 m in the Plio- Pleistocene Pinecrest beds (Tamiami Formation, southern Florida) and found significant spatial vari- ability in predation trace frequencies (drillholes and repair scars) among marine mollusks (ranging from 0.03 to 0.11 for all mollusks combined). We then explored potential causes for the variability we observed. Overall, there was little inter-sample...
