Acrodus(fromGreek:άκροςákros,'high' andGreek:ὀδούςodoús'tooth')[2]is an extinct genus ofhybodontspanning from the EarlyTriassic[3]to theLate Jurassic.[4](The Early Cretaceous species"Acrodus" nitidusaffinity to the genus is questionable.[5]) It wasdurophagous,with blunt, broad teeth designed for crushing and grinding.[6]Some Middle Triassic species have been suggested to have grown to lengths of 1.8–2.5 metres (5.9–8.2 ft).[7]Species are known from both marine and freshwater environments, with all Middle and Late Jurassic species only known from freshwater.[4]
