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