A NEW SPECIES OF BROTIA H. ADAMS, 1866 (CAENOGASTROPODA: CERITHIOIDEA: PACHYCHILIDAE) [PDF]
Journal of Molluscan Studies, 2002 A new species, Brotia praetermissa, is described from Borneo. The type material was found unidentified in the spirit collection of the Natural History Museum, London. It was collected by A. Everett in the nineteenth century. Using morphological characters, the new species is affiliated with the Brotia pago-dula species group.

Evolutionary systematics of the viviparous gastropod Sermyla (Gastropoda: Cerithioidea: Thiaridae), with the description of a new species [PDF]
Zoological Journal of the Linnean Society, 2020 Abstract While most Cerithioidea are marine, some occur in brackish and freshwater habitats. Many members are systematically problematic due to variability or homoplasy in conchological characters, which has led to taxonomic redundancy, but also because of discrepancies between phylogenetic trees and morphologically distinguishable units

Papers in Palaeontology, Volume 10, Issue 4, July/August 2024.Abstract We describe a high‐diversity silicified assemblage of marine molluscs (Pelsa‐Vazzoler Lagerstätte) from the upper Ladinian of the Agordo Dolomites (northeastern Italy). New data on the Triassic rebound, after the end‐Permian mass extinction, constrain it to an interval of relatively stable climatic conditions.

The fossil record of freshwater Gastropoda – a global review
Biological Reviews, Volume 99, Issue 1, Page 177-199, February 2024.ABSTRACT Gastropoda are an exceptionally successful group with a rich and diverse fossil record. They have conquered land and freshwater habitats multiple times independently and have dispersed across the entire globe. Since they are important constituents of fossil assemblages, they are often used for palaeoecological reconstruction, biostratigraphic ...

Detection of intact polyene pigments in Miocene gastropod shells
Palaeontology, Volume 67, Issue 1, January/February 2024.Abstract Polyene pigments represent a major class of pigments in present‐day organisms. Their occurrence in fossils has been frequently discussed, but to date no spectroscopic evidence has been found. Here, we use in situ Raman spectroscopy to examine the chemistry of exceptionally well‐preserved gastropod shells with colour preservation from the ...

Morphological and Genetic Variation Between the Japanese Populations of the Amphidromous Snail Stenomelania crenulata (Cerithioidea: Thiaridae) [PDF]
Zoological Science, 2014 Freshwater gastropods often have limited dispersal capability and small geographic ranges, and face severe threats from habitat loss and degradation. However, in addition to the scarcity of knowledge on their life history traits, species taxonomy has not been adequately resolved and boundaries between intra- and interspecific variation remain unclear ...
