Eryonidae is a family of fossil decapod crustaceans which lived from the Upper Triassic to the Lower Cretaceous.^[1] It contains four genera:^[2] An aggregation of three unidentified eryonids was reported in 2012 inside a Late Jurassic ammonoid of the species Harpoceras falciferum; they represent the earliest evidence of gregarious behaviour in decapods.^[3]
