2016 in paleomalacology

This list, 2016 in molluscan paleontology, is a list of new taxa of ammonites and other fossil cephalopods, as well as fossil gastropods, bivalves and other molluscs that have been described during the year 2016.

Ammonites

Research A study on the phylogenetic relationships of the Middle Jurassic ammonites from India is published by Dutta & Bardhan (2016), who name a new perisphinctid subfamily Sivajiceratinae. Ammonite embryonic shell clusters preserved within the body chambers of mature macroconch shells of the Early Cretaceous (Aptian) ammonite Sinzovia sazonovae are described by Mironenko & Rogov (2016), who interpret the finding as indicative of ovoviviparity in at least some ammonites.
