Recent discoveries show that metriorhynchids evolved a wide range of craniodental morphotypes and inferred feeding strategies. One genus, <jats:italic>Dakosaurus<\/jats:italic>, is arguably the most aberrant marine crocodylomorph due to its large, robust, ziphodont teeth; very low tooth count; and brevirostrine\/oreinirostral snout. We here report an additional unusual feature of <jats:italic>Dakosaurus<\/jats:italic> that is unique among marine crocodylomorphs: tightly fitting tooth\u2010to\u2010tooth occlusion, whose inference is supported by reception pits along the upper and lower tooth rows, indicative of vertically orientated crowns that were in close contact during occlusion, and three distinct types of dental wear. These include irregular spalled surfaces near the apex (probably caused by tooth\u2010food contact), semi\u2010circular wear near the base, and elongate surfaces extending along the mesial and distal margins of the teeth, obliterating the carinae (including the denticles). Scanning electron micrographs show that these latter surfaces are marked by parallel apicobasal striations, which in extant mammals reflect tooth\u2013tooth contact. As such, we interpret the carinal wear facets in <jats:italic>Dakosaurus<\/jats:italic> as being formed by repeated tooth\u2013tooth contact between the mesial and distal margins of the teeth of the upper and lower jaw. We posit that this increased the available shearing surface on their high crowns. Together, these wear patterns suggest that occlusion in <jats:italic>Dakosaurus<\/jats:italic> was specialized for cutting large and abrasive prey items into portions small enough to swallow, making it a prime example of an aquatic reptile with macrophagous feeding habits.
