Tide-dominated beaches are widespread in today's world, and coastal researchers have recently begun to address their sedimentary character, finding that they differ notably from the more familiar, purely wave-dominated beaches. Nonetheless, ancient tide-dominated beaches are infrequently recognized, perhaps for want of suitable sedimentological criteria and facies models. Smosna and Bruner present the facies reconstruction of The Cambro-Ordovician Cabos Formation of northern Spain, a system interpreted to represent an ancient tide-dominated beach system. In describing sedimentologic observations and the criteria on which the interpretation is based, this analysis constitutes a beginning step in constructing the sedimentological framework for a virtually unknown (or at least poorly documented) paleoenvironment.
