Acrodus (from Greek: άκρος ákros, 'high' and Greek: ὀδούς odoús 'tooth')[1] is an extinct genus of hybodont spanning from the Early Triassic[2] to the Late Jurassic.[3] (The Early Cretaceous species "Acrodus" nitidus affinity to the genus is questionable.[4]) It was durophagous, with blunt, broad teeth designed for crushing and grinding.[5] Some Middle Triassic species have been suggested to have grown to lengths of 1.8–2.5 metres (5.9–8.2 ft).[6] Species are known from both marine and freshwater environments, with all Middle and Late Jurassic species only known from freshwater.[3]
