General research

  • A study aiming to determine the drag force experienced by a wide range of ammonite shell shapes is published by Hebdon, Ritterbush & Choi (2020).[36]
  • A study evaluating how different parameters affected the ammonite shell's response to water pressure, aiming to determine whether the ammonite septa strengthened the shell against pressure at increasing water depths, is published by Lemanis (2020).[37][38][39]
  • A study on global patterns of ammonite diversification and extinction from the Early Devonian (Emsian) to the Early Triassic (Induan) is published by Whalen, Hull & Briggs (2020).[40]
  • A study on the abundance and size distribution of small specimens of Baculites and Hoploscaphites at eight cold methane seep sites in the Upper Cretaceous Pierre Shale (South Dakota, United States) is published by Rowe et al. (2020), who interpret their findings as indicating that newly hatched ammonites lived in close proximity to seep fluids emerging at the sediment-water interface and the associated microbial food web.[41]
  • A study on changes of hydrostatic properties of three species of Didymoceras during their ontogeny is published by Peterman et al. (2020).[42]

Research

  • New specimens of Pelagiella exigua with associated impressions of two clusters of chaetae, providing new information on the anatomy of this taxon, are described from the Cambrian Kinzers Formation (Pennsylvania, United States) by Thomas, Runnegar & Matt (2020), who infer the occurrence of a pair of chaeta-bearing appendages extending from the anterior body wall or foot of the animal (unique among living and extinct molluscs), and interpret Pelagiella as the earliest known stem gastropod.[152]
