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 placed in the gastroceratoidea, "proshunardites" combined with "dombarites" in the delepinoceratidae. the two added genera, "gaetanoceras" and "paragathiceras", were considered as equivalent to "agathiceras" in miller "et al." (1960).
