Phylogenetic analyses may suffer from multiple sources of error leading to conflict between genes and methods of inference. The evolutionary history of the mollusc clade Vetigastropoda makes them susceptible to these conflicts, their higher level phylogeny remaining largely unresolved. Originating over 350 Ma, vetigastropods were the dominant marine snails in the Paleozoic.

Past phylogenetic efforts to resolve gastropod relationships resulted in a range of conflicting hypotheses. Here, we use phylogenomics to address deep relationships between the five major gastropod lineages-Caenogastropoda, Heterobranchia, Neritimorpha, Patellogastropoda and Vetigastropoda-and provide one congruent and well-supported topology.

- - Fissurellidae are a diverse group of marine snails, and this research uses molecular, geographical, and fossil evidence to clarify their evolutionary relationships and dispersal patterns.
- - The study finds that many current genera classifications are incorrect and suggests a need for systematic revisions, particularly in the Emarginulinae group, while also estimating that these snails originated around 175 million years ago.
- - Biogeographic analysis indicates that fissurellids likely originated in the Indo-West Pacific region and spread westward after Pangea's breakup, with established new synonyms and a new subfamily designation for Rimula in the process.
