''Lecanites'' is a ceratitid genus assigned to the Danubitaceae, with an essentially smooth, evolote, discoidal shell and a goniatitic suture with many elements. It is the type and now only genus of the Lecanitidae. Previously, according to the Treatise Part L, ''Lecanites'' and ''Badiotites'' were included together in the Lecanitidae which then was part of the Clydonitaceae. Since then (Tozer 1981) Badiotites was reassigned to the new family Badiotitidae which is included in the Ceratitaceae and Lecanites and Lecanitidae put to the Danubitaceae. ''Lecanites'' was named by Mojsisovics in 1882. It has been found in the middle and upper Triassic of California, Nevada, Idaho, China, and Italy. ==''References''== *Treatise on Invertebrate Paleontology, Part L, Ammonoidea. R. C. Moore (ed).
