(Miller ''et al.'' 1960) The explanation for the Agathiceratidae is that for the Agathiceratoidea. Agathiceratidae may have its origin in ''Dombarites'' (Saunders ''et al.'' 1999) which has been removed to the Delepinoceratidae (Furnish ''et al.'' 2009). Delepinoceratidae is now one of two families that make up the Goniatitoidea. In current taxonomy (Furnish ''et al.'' 2009), Agathiceratidae contains '' Agathiceras'', '' Gaetanoceras'', '' Paragathiceras'', and '' Pericleites'' as compared to ''Dombarites'', '' Paracravenoceras'', ''Periclietes'', '' Proshumardites'', and ''Agathiceras'' in Saunders ''et al.'' (1999). ''Paracravenoceras'' is now ...
