Flickiidae is a family of dwarf ammonites with little ornament and very simples sutures known from small pyritic specimens found in middle Cretaceous deposits. Inclusion in the Acanthoceratoidea is tentative. ==Taxonomy== Flickiidae has been divided into two subfamilies, the Flickiinae, which is equivalent to the Flickiidae of the Treatise on Invertebrate Paleontology, Part L, 1957 and the Salaziceratinae which contains ''Salaziceras'', moved from the Lyelliceratidae and ''Neosaynoceras'', moved from the Acanthoceratidae. Genera now in the Flickiinae: :''Flickia'', Pervenquiere 1907. Shell smooth, moderately evolute, rather compressed, venter narrowly arched, suture smooth, undulatory. U Alb -L Cenom. N Afr, Madag, Texas. :''Ficheuria'', Pervenquiere 1907. Shell very involute, globular, umbilical shoulder tending to be angular. Suture similar to that of Flickia. U Alb. -L Cenom. of North Africa. :''Adkinsia'', Boes 1928. Shell rather more involute and inflated than ''Flickia'' but less than ''Ficheuria''; first lateral lobe narrower than on either. L Cenom, Texas. Genera placed in the Salaziceratinae: :''Salaziceras'', Breistroffer, 1936. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Flickiidae」の詳細全文を読む スポンサード リンク
