Other cephalopods
Research
- A study on the distribution and diversity of cephalopods during the Cambrian–Ordovician transition will be published by Fang et al. (2019).[2]
- Ascocerid fossils will be described from the Hirnantian?–Llandovery strata of the Eusebio Ayala and Vargas Peña formations (southeastern Paraguay) by Cichowolski et al. (2019), representing the first ascocerid record from high paleolatitudes of Gondwana.[3]
- Mironenko (2019) proposes a new hypothesis about the habits and feeding strategies of endocerids, interpreting them as planktotrophic cephalopods, and arguing that the largest of endocerids were suspension feeders.[4]
- Antarcticeras nordenskjoeldi Doguzhaeva in Doguzhaeva et al. (2017), originally assigned to a new cephalopod subclass Paracoleoidea and the new order Antarcticerida, is reinterpreted as a possible member of Oegopsida by Fuchs, Keupp & Klug (2019);[5] this reinterpretation is subsequently criticized and rejected by Doguzhaeva (2019).[6]

Fuchs |
Kimmeridge Clay Formation |
A member of Coleoidea belonging to the family Muensterellidae. Genus includes new species E. martilli. |
Gastropods
Research
- A probable cyclophoroidean gastropod, possibly a member of the family Cyclophoridae, will be described from the Cretaceous amber from Myanmar by Xing et al. (2019), constituting the first confirmed and oldest record of soft-bodied preservation of a snail in Cretaceous amber.[8]
