""'Fagesia " "'is a small, subglobular ammonite ( suborder Ammonitina ) belonging to the vascoceratid family of the Acanthocerataceae that lived during the Turonian stage of the late Cretaceous, 92-88 Ma ago.

"Posttornoceras ", type genus of the Posttornoceratinae was named by Wedekind in 1910 . " Posttornoceras " has a subglobular to discoidal shell with a small, closed umbilicus and biconvex growth lines ( Miller et al . 1964 ).

"' Thalassoceratoidea "', formerly "'Thalassocerataceae "', is a superfamily of Late Paleozoic ammonites characterized by their thick-discoidal to subglobular, involute shells with narrow or closed umbilici and biconvex growth striae with ventral sinuses.
24.
"Texoceras ", named and described by Miller & Furnish in 1937, has an involute, subglobular shell, like " Adrianites ", with a narrow, deep umbilucus in the middle, but with a reticulate surface and a suture that forms 14 rounded lobes.
25.
""'Liroceras " "'is the type genus of the clydonautiliacean family, Liroceratidae, and is characterized by a rapidly expanding, subglobular, nautiliconic shell with a reniform whorl section, small umbilicus, essentially straight sutures, and a siphuncle with a variable but not marginal position.
26.
"Asklepioceras ", named by Renz, 1910, is characterized by evolute to involute, discoidal to subglobular shells with a median ( ventral ) furrow not borndered by keels ( in contrast to Dittmarites in which it is ) and simple ceratitic sutures . ( Arkell et al . 1962, L162 ) The genotype " Asklepioceras segmentatus"
27.
Discoclymenia has a subglobular to discoidal shell with a small, closed umbilicus, like " Sporadoceras " but with additional adventitious lobes in the 1st lateral saddles . " Discoclymenia " and " Sporadoceras " are included in the subfamily Sporadoceratinae of Miller and Furnish ( 1964 ) along with " Praeglyphioceras " according to Miller et at ( 1964 ) . " Discoclymenia " comes from the Upper Devonian of Europe and North Africa.
