* History of science portal
This list, 2017 in paleomalacology, is a list of new taxa of ammonites and other fossil cephalopods, as well as fossil gastropods, bivalves and other molluscs that are scheduled to be described during the year 2017, as well as other significant discoveries and events related to molluscan paleontology that are scheduled to occur in the year 2017.

## Ammonites
### Research

* A study on the relationship between hatchling size and geographical ranges in ammonites, as well as on the relationship between geological duration and geographical ranges of ammonites, is published by Wani (2017).
* A study on the holotype specimen of the Devonian species Ivoites opitzi, aiming to establish whether sclerobionts settled on the specimen during its life and whether they were responsible for the coiling observed in this specimen, is published by Stilkerich, Smrecak & De Baets (2017).
* Goolaerts, Denayer & Mottequin (2017) interpret the fossils of Ellipsocaris dewalquei and Spathiocaris chagrinensis from the Devonian (Frasnian) of Belgium, originally thought to be crustacean shields, as ammonoid anaptychi, and consider the genus Ellipsocaris to be a junior synonym of the genus Sidetes.
* A study on the inner shell structure in several ammonite taxa from the Triassic (Olenekian) of southern Primorye (Russia) and its implications for the phylogenetic relationships of Early Triassic ammonites is published by Smyshlyaeva & Zakharov (2017).
* An 8.5 m long ammonite drag mark with the preserved shell of Subplanites rueppellianus at its end is described from the Solnhofen limestone (Germany) by Lomax et al. (2017).
* A study on the taxonomic status of the perisphinctid genus Hubertoceras from the Middle Jurassic of India is published by Dutta et al. (2017), who interpret Hubertoceras as a junior synonym and microconch of the genus Obtusicostites.
* A study on the occurrences of Albian ammonite fossils and their implications for the biogeography of Albian ammonites is published by Rojas et al. (2017).
