''Michiganites'' is a member of the ammonoid order Prolecanitida, named by Ruzhencev in 1962, which comes from the Meramacian stage of Mississippian Period (early Carboniferous Visian). The shell of ''Michiganites'' is discoidal and smooth, as for the family. The ventral lobe of the suture is expanded; three lobes are formed on either side. ''Michiganites'' is placed in the suborder Prolecanitinae (the Prolecanitaceae of Hyatt 1884) and in the family Prolecanitidae along with related genera, ''Becanites'', ''Dombarocanites'', ''Eocanites'', ''Katacanites'', ''Metacanites'', and ''Prolecanites'' ==References==
