To re-evaluate the relationships of major bivalve lineages, we amassed detailed morpho-anatomical, ultrastructural and molecular sequence data for a targeted selection exemplar bivalves spanning phylogenetic diversity class. We included 103 species (up to five markers) also analysed subset taxa with four additional nuclear protein-encoding genes. Novel as well historically employed morphological characters were explored, systematically disassembled widely used descriptors such gill stomach...
Cultural artefacts, like genes and languages, reflect their history. The methodology of inference that history, however, has been a contentious question. Recent applications biological phylogenetic to infer historical patterns material culture are often explicitly justified on the grounds essentially similar processes underlie evolution in both cultural realms. Conventional techniques, while helpful some cases, do not provide general theoretical operational framewok for reconstructing...
The superfamily Pterioidea is a morphologically and ecologically diverse lineage of epifaunal marine bivalves distributed throughout the tropical subtropical continental shelf regions. This group includes commercially important pearl culture species model organisms used for medical studies biomineralization. Recent morphological treatment selected pterioideans molecular phylogenetic analyses higher-level relationships in Bivalvia have challenged traditional view that pterioidean families are...
The evolutionary relationships of the Recent Pterioidea are inferred from a phylogenetic analysis representatives all pterioidean genera based on original observations anatomy and shell morphology, an extensive survey bivalve literature. well-resolved cladogram supports monophyly for superfamily, but renders one family (the monotypic Pulvinitidae) polyphyletic. In addition, these results reveal considerable level convergence parallelisms through Pterioidea. branching order pterioid in...
Abstract The theory of punctuated equilibria, introduced in paleobiology, postulates enduring morphological stability species interrupted by rapid phenotypic change at speciation events. It played a pivotal role evolutionary biology, reshaping perspectives and triggering conceptual shift redefining as discrete entities, paving the way for hierarchical model organic world. This approach initially faced limited attention but experienced resurgence new millennium. revived interest models,...

Carnivory is unusual among bivalve molluscs and limited to a few families in the distantly related orders Pectinida, Mytilida Anomalodesmata. Despite significance of dietary shifts evolution bivalves, anatomy alimentary system, gastric chamber particular, has been described detail for only carnivorous species. Here we describe pectinid, Propeamussium jeffreysii, an anomalodesmatan, Bathyneaera demistriata, expanding known morphological disparity system both groups. We found stomachs be...
Isognomon spathulatus (Reeve, 1858) is redescribed based on type material and original collections from Kungkrabaen Bay, Thailand. The species agrees with previously described isognomonids in most conchological anatomical features, but possesses a suite of diagnostic characters, including comma-shaped outline the nacreous border, an uncoiled ventral diverticulum stomach, thickened mantle lobes granulated cells. This study comprehensive morphological analysis to date for any Isognomonidae...
Pulvinites exempla is the only living species of marine bivalve family Pulvinitidae. Previously, has been known exclusively from cursory analyses gross shell morphology. The present study first description soft anatomy, microstructure, and early ontogeny ligament in this species. Many aspects morphology described herein are unique to P. exempla, considerably expanding degree morphological disparity within superfamily Pterioidea. features body plan affected by extensive torsion pedobyssal...
Mantellina translucens n. sp. inhabits the deep reefs (215–310 m) off southeastern Curaçao, occurring singly or in pairs, attached to vertical rock walls and boulders by thin byssal threads. This species differs from all living Limidae having an exceptionally thin, comarginally corrugated shell that is longer than tall lacks radial sculpture. new possesses a unique suite of characters associated with adaptations epibyssate mode life bathyal habitats, including simplification digestive tract,...
An exceptionally well-preserved silicified bivalve from the Upper Permian of Texas is described and assigned to a new genus species, Cassiavellia galtarae , placed in family Bakevelliidae. The species represents one earliest best characterized unequivocal occurrences multivincular ligament superfamily Pterioidea. material provides wealth information on morphology inadequately known Paleozoic pterioideans, including hitherto undescribed aspects larval shell, auricular sulcus, muscle scars,...
Wilhelm Dunker was the foremost expert on systematics of bivalve family Pteriidae (referred to as genus Avicula in his time) nineteenth century. His work group culminated monograph Die Gattung Avicula, a part significant conchological iconography, Systematisches Conchylien-Cabinet (Küster et al., 1837–1920). Dunker's volume remains unsurpassed taxonomic scope and quality illustrations. However, despite fact that readily available widely cited, few specialists consulted actual type material...
The application of conventional phylogenetic techniques for inferring cultural history is problematic due to differences in the nature information transmission biological and realms. In culture, units are not just measurable attributes, but communicable concepts. Therefore, relatedness amongst elements often resides at conceptual level captured by traditional methods. This paper takes a cognitively inspired approach analyzing material history. We show that combining data physical attributes...
