Lecanites
Encyclopedia
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 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.
Ceratitida
The Ceratitida is an order that contains almost all ammonoid cephalopod genera from the Triassic as well as ancestral forms from the Upper Permian, the exception being the phylloceratids which gave rise to the great diversity of post Triassic ammonites....
