Psammodontidae is an extinct family of holocephalans (sometimes referred to as bradyodonts) ^[1] known from the Carboniferous and Permian periods. ^[2] It is the only family of the order Psammodontiformes. ^[2] The order and family are named for the type genus, Psammodus , and all members are believed to have been durophagous nektobenthic carnivores. ^[3] The only described remains assigned to Psammodontidae are isolated tooth plates. ^[1]
