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… 

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.


Abstract Biotic Immigration Events (BIMEs) record the large-scale dispersal of taxa from one biogeographic area to another and have significantly impacted biodiversity throughout geologic time. BIMEs

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 toward modern conditions, and many flora and

Emergence of a sixth mass extinction

Evidence is found that human-caused extinctions have amounted to only about 1.5 species per year for the last 500 years and that these losses have probably been equalled or surpassed by species born (speciation) during that time.

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.

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.

Examining the latitudinal diversity gradient in Paleozoic terebratulide brachiopods: should singleton data be removed?

Methods that can accommodate singleton taxa should be used to study the diversity of Paleozoic terebratulides and possibly other well-skeletonized marine metazoans, as the taxon age metric considers origination and extinction simultaneously.

An empirical assessment of taxic paleobiology.

The authors' comprehensive database of trilobites is compared to the equivalent portion of J. Sepkoski Jr.'s widely used global genus database; more than 70% of entries in the global database are inaccurate; however, as predicted, the error is randomly distributed and does not introduce bias.

Geologic constraints on the macroevolutionary history of marine animals.

This work compares the rates of expansion and truncation of preserved marine sedimentary basins to rates of origination and extinction among Phanerozoic marine animal genera and suggests that the processes responsible for producing variability in the sedimentary rock record, such as plate tectonics and sea-level change, may have been dominant and consistent macroevolutionary forces throughout the Phanrozoic.
