Multi-storm events recorded on Panopea burrows (Pliocene, Spain): The importance of sequestered information inside burrows

These shell concentrations inside Scalichnus burrows constitute a potential sedimentological implement to understand the multi-storm events recorded on the taphonomic signature of the biofabric that otherwise may be unnoticed. The studied examples can be used as proxies for sequencing a series of amalgamated storm events inside bivalve burrows, assessing the magnitude and frequency of erosional events, and analysing the positive taphonomic effect of these equilibrium trace fossils.
