This Lituites leei from China offers a fine and detailed preservation that goes nearly completely down to the inner parts of the coil.
The species Lituites leei shows the some affinity to Baltic Lituites perfectus WAHLENBERG ,1818. Lituites leei is characteristic for the limestone facies of the der Datianba Formation that corallites principally with the Nemagraptus gracilis Biozone.
About the higher systematic relation of the Lituites Cephalopod group* is to say that it is not at all the ancestor group of the Ammonites.
