An elusive ancestry of Neogastropoda: a potential of Maturifusidae, Pseudotritoniidae, and Purpurinidae as the stem groups

This dataset contains the digitized treatments in Plazi based on the original journal article Bakayeva, Sofia, Nützel, Alexander, Kaim, Andrzej (2024): An elusive ancestry of Neogastropoda: a potential of Maturifusidae, Pseudotritoniidae, and Purpurinidae as the stem groups. Comptes Rendus Palevol 23 (31): 481-509, DOI: 10.5852/cr-palevol2024v23a31, URL: doi.org/10.5852/cr-palevol2024v23a31 ABSTRACT Notwithstanding considerable efforts and new data on gastropod evolution collected in the recent decades, the origin of Neogastropoda remains still elusive.

In this contribution we compare and discuss members of three extinct families previously proposed as possible neogastropod stem groups, i.e., Maturifusidae Gründel, 2001, Pseudotritoniidae Golikov & Starobogatov, 1987, and Purpurinidae Zittel, 1895. Their morphological characteristics, especially the differences in protoconch morphology, strongly suggest that they should all be considered as separate clades. The taxonomic status and the composition of each family is here reviewed and accordingly revised.
