How do you extract tiny shark dermal denticles from marine sediments and how can they be used to reconstruct shark communities? In this new paper, Erin Dillon, Dick Norris and myself explore the technique and discuss the potentials, pitfalls and limitations of the approach with the aim of building a better understanding of shark communities today and in the past.
This study will help us interpret fossil and modern assemblages of dermal denticles when we consider how shark communities have changed over historical time in response to fishing (of sharks themselves and their prey), pollution and habitat change.
