There were fewer crab predation traces on modern gastropods than their Pleistocene counterparts, revealing reductions in crab abundances today compared to the Pleistocene. We compared crab predation traces on living individuals of the crab prey gastropod, Tegula funebralis, to Pleistocene individuals from the same regions in southern California. Here, we provide the first use of predation traces to assess the status of fisheries (crab). Fossil data provide pre-anthropogenic baselines for data-poor fisheries, yet are underutilized in fisheries management. 2Department of Earth and Atmospheric Sciences, University of Alberta, Edmonton, AB, Canadaĭespite growing concerns over global fisheries, the stock status of most commercially exploited species are poorly understood.1Departments of Biology and Anthropology, University of Victoria, Victoria, BC, Canada.
