Genera

Angustidontidae is an extinct family of eucarid crustaceans and the sole representatives of the order Angustidontida. They were predators ranging in size from about 4 to 9 cm (1.6 to 3.5 in) in length and lived during the Late Devonian and Early Carboniferous periods.[1]

They were some of the earliest Eucarids to develop maxillipeds, modified from the first or second thoracopods.[1] They were originally considered eurypterids, but later their possible relationship with decapods was established.[1][2]
