Adamsoceras ✝
Description | Adamsoceras is a genus of actinocerids of the family Wutinoceratidae, with spheroidal siphuncle segments like Ormoceras, but having a reticular canal system like Wutinoceras. Adamsoceras has a slender, gently expanding, orthoconic shell that is slightly broader than high, i.e. depressed, with close spaced septa that form ventral lobes and a siphuncle that is near the ventral margin.
