Falcatidae is a family of Paleozoic cartilaginous fish belonging to the order Symmoriiformes.[1] Members of this family include Falcatus, a small fish from the Bear Gulch Limestone of Montana.[2] The family first appeared around the start of the Carboniferous, and there is some evidence that they survived well into the early Cretaceous,[3] though its putative Cretaceous members were also argued to be more likely neoselachians.[4]
