Abstract. This study uses a comprehensive, revised, and updated global bivalve dataset combining information from two major databases available to study temporal trends in Phanerozoic bivalve richness: the Sepkoski Compendium and the Paleobiology Database. This compilation results in greater taxonomic and stratigraphic coverage than possible with either of the two databases alone. However, there are challenges in directly comparing these two sources due to differences in their taxonomic… 
Phanerozoic trends in ecospace utilization: The bivalve perspective
This Phanerozoic-level study on the Class Bivalvia, a group with a very robust and virtually unparalleled fossil record, the clade's ecologic diversity is reconstructed based on a set of newly compiled taxonomic and ecologic databases that were initially derived from a combination of the Sepkoski Compendium and the Paleobiology Database.
Were bivalves ecologically dominant over brachiopods in the late Paleozoic? A test using exceptionally preserved fossil assemblages
Abstract. Interpreting changes in ecosystem structure from the fossil record can be challenging. In a prominent example, the traditional view that brachiopods were ecologically dominant over
Burrowers from the Past: Mitochondrial Signatures of Ordovician Bivalve Infaunalization
Selective signatures on bivalve and gastropod mitochondrial genomes with respect to a time calibrated mitochondrial phylogeny are investigated by means of dN/dS ratios, detecting a major signal of directional selection between the Ordovician and the Lower Devonian for bivalves mitochondrial Complex I and an overall higher directional selective pressure onbivalve Complex V withrespect to gastropods.
Trophic and tectonic limits to the global increase of marine invertebrate diversity
It is suggested that the time elapsed between the formation and destruction of ocean basins influences the diversity dynamics of marine invertebrates and may have contributed to constrain their diversification.
When fossil clades ‘compete’: local dominance, global diversification dynamics and causation
Comparison of time-series models using linear stochastic differential equations suggests that inter-clade genus origination and extinction rates are causally linked to each other in a complex feedback relationship rather than by simple correlations or unidirectional relationships.
Biotic immigration events, speciation, and the accumulation of biodiversity in the fossil record
A conceptual model for biodiversity accumulation that links BIMEs and geographic isolation with local (α) diversity, regional (β) Diversity, and global (γ) diversity metrics is developed and tested using a series of case studies from the paleontological record.
Are local dominance and inter-clade dynamics causally linked when one fossil clade displaces another?
A fortified and vetted compilation of 40190 fossil species occurrences of cyclostome and cheilostome bryozoans provides a canonical example of one taxonomically dominant clade being displaced by another, suggesting that global fossil diversification rates and local taxonomic dominance are not causally linked.
Calibrating phylogenies assuming bifurcation or budding alters inferred macroevolutionary dynamics in a densely sampled phylogeny of bivalve families
This work uses the extensive fossil record of bivalve molluscs for a large-scale evaluation of how branching models affect macroevolutionary analyses, and time-calibrated 91% of nodes, ranging in age from 2.59 to 485 Ma, in a phylogeny of 97 extant bivalves.
Comparative Large-Scale Mitogenomics Evidences Clade-Specific Evolutionary Trends in Mitochondrial DNAs of Bivalvia
This work constructed a dataset of one hundred mitochondrial genomes of bivalves to perform the first systematic comparative mitogenomic analysis, developing a phylogenetic background to scaffold the evolutionary history of the class' mitochondrial genomes.
The Miocene: The Future of the Past
The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned towards modern conditions, and many flora

A new database of this kind for the Phanerozoic fossil record of marine invertebrates is introduced and four substantially distinct analytical methods that estimate taxonomic diversity by quantifying and correcting for variation through time in the number and nature of inventories are applied.
Biodiversity in the Phanerozoic: a reinterpretation
Abstract Many features of global diversity compilations have proven robust to continued sampling and taxonomic revision. Inherent biases in the stratigraphic record may nevertheless substantially
A revised macroevolutionary history for Ordovician–Early Silurian crinoids
Removing taxonomic and stratigraphic errors in Sepkoski's compendium substantially changes the understanding of the nature of large-scale biotic change for an important Paleozoic taxon during the end-Ordovician.
Permian marine paleoecology and its implications for large-scale decoupling of brachiopod and bivalve abundance and diversity during the Lopingian (Late Permian)
Abstract The transition during the Permian–Triassic interval from brachiopod-rich benthic marine assemblages to communities with diverse molluscs has been well constrained by measures of global
Preservation biases, rates of evolution and coherence of databases: Bivalvia as a study case
Abstract. Several hypotheses about the influence of preservation on Bivalvia rates of evolution estimates (marine and freshwater families) were tested in a previous paper. However, the database used
Evolutionary Patterns in the Paleozoic Bivalvia: Documentation and Some Theoretical Considerations
The fossil record of the Paleozoic Bivalvia can be described in terms of directional and repetitive evolutionary trends. The directional aspect is reflected in long-term generic diversification, and
Biogeography of recent marine bivalve molluscs and its implications for paleobiogeography and the geography of extinction: A progress report
The geographic distribution of Recent taxa is important in interpreting paleobiogeography and the fossil record of extinction. We examine the latitudinal diversity gradient in Recent marine bivalve
Evolution of taxonomic diversity gradients in the marine realm: evidence from the composition of Recent bivalve faunas
A taxonomic and stratigraphic analysis reveals that the steepest latitudinal gradients are associated with the youngest bivalve clades, providing further evidence that the Tropics have served as a major center of evolutionary innovation.
The effects of taxonomic standardization on sampling-standardized estimates of historical diversity
This work contrasts diversity patterns and diversity dynamics between raw data and taxonomically vetted data in the PBDB to evaluate the effects of taxonomic errors and finds that taxonomic standardization can elevate diversity dynamics in some cases, but it will not greatly change inferred richness over time.
