Research[]

  • A study on the diversity of gastropod larval conch fossil assemblages of ages ranging from the Ordovician to Carboniferous is published online by Dzik (2019).[89]
  • A study on the recovery of gastropods in the aftermath of the Cretaceous–Paleogene extinction event, based on data from fossils from the former Ankerpoort‐Curfs quarry (Geulhem, the Netherlands), is published online by Vellekoop et al. (2019).[90]
  • A probable cyclophoroidean gastropod, possibly a member of the family Cyclophoridae, is 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.[91]
  • A study on the nature of the size dimorphism in the Miocene gastropod , and on the causes of its evolution, is published by Halder & Paira (2019).[92]
  • New specimens of are described from the Miocene Gram Clay of Denmark by Schnetler (2019), who also provides an emended description of this species.[93]
  • A revision of extant and Neogene members of the genus from the southwestern Atlantic Ocean is published by Pastorino & Griffin (2019).[94]
