Modelling has been underdeveloped with respect to constructing palaeobiodiversity curves, but it offers an additional tool for removing sampling from their estimation. Here, an alternative to subsampling approaches, which often require large sample sizes, is explored by the extension and refinement of a pre-existing modelling technique that uses a geological proxy for sampling. Application of the model to the three main clades of dinosaurs suggests that much of their diversity fluctuations…

Dinosaur diversification rates were not in decline prior to the K-Pg boundary
Bayesian phylogenetic generalized linear mixed models are used to assess the fit of 12 dinosaur phylogenies to three speciation models, which suggest that dinosaur speciation rates were not in terminal decline prior to the K-Pg boundary and that the clade was still capable of generating new taxa.
Early tetrapod diversification under neutral theory
Estimates of deep-time biodiversity typically rely on statistical methods to mitigate the impacts of sampling biases in the fossil record. However, these methods are limited by the spatial and
The early evolution of synapsids, and the influence of sampling on their fossil record
Assessment of synapsid diversity, at both the species and genus levels, between the Carboniferous (Moscovian) and the Middle Permian (Capitanian) calls into question previous diversity studies that have not employed sampling correction.
Phanerozoic marine diversity: rock record modelling provides an independent test of large-scale trends
Using the fossil records of North America and Western Europe, it is demonstrated that a modelling approach applied to the combined data produces results that are significantly correlated with those derived from subsampling.
Palaeontology meets metacommunity ecology: the Maastrichtian dinosaur fossil record of North America as a case study
Documenting the patterns and potential associated processes of ancient biotas has always been a central challenge in palaeontology. Over recent decades, intense debate has focused on the organization
Assessing sampling of the fossil record in a geographically and stratigraphically constrained dataset: the Chalk Group of Hampshire, southern UK
Taphonomic, geological and sampling processes have been cited as biasing richness measurements in the fossil record, and sampling proxies have been widely used to assess this. However, the link
How has our knowledge of dinosaur diversity through geologic time changed through research history?
This work investigates the influence of publication history between 1991 and 2015 on the understanding of dinosaur evolution using raw diversity estimates and shareholder quorum subsampling for the three major subgroups: Ornithischia, Sauropodomorpha, and Theropoda.


Dinosaur diversity and the rock record
Strong statistically robust correlations demonstrate that almost all aspects of ornithischian and theropod diversity curves can be explained by geological megabiases, whereas the sauropodomorph record diverges from modelled predictions and may be a stronger contender for identifying evolutionary signals.

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.
Testing the effect of the rock record on diversity: a multidisciplinary approach to elucidating the generic richness of sauropodomorph dinosaurs through time
Despite its distortion by sampling biases, much of sauropodomorph palaeobiodiversity can be interpreted as a reflection of genuine biological signals, and fluctuations in sea level may account for some of these diversity patterns.
Abstract:  Palaeodiversity curves are constructed from counts of fossils collected at outcrop and thus potentially biased by variation in the rock record, specifically by the amount of sedimentary
Sea level, dinosaur diversity and sampling biases: investigating the ‘common cause’ hypothesis in the terrestrial realm
The fossil record is our primary window onto the diversification of ancient life, but there are widespread concerns that sampling biases may distort observed palaeodiversity counts. Such concerns

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.
Mesozoic marine tetrapod diversity: mass extinctions and temporal heterogeneity in geological megabiases affecting vertebrates
Some evidence supports an extinction event near the Jurassic/Cretaceous boundary, but the proposed end-Cenomanian extinction is probably an artefact of poor sampling, and consideration of sampling biases allows re-evaluation of proposed mass extinction events.

Future assemblies of animals following mass extinction cannot be predicted by analyses of Phanerozoic fossils, and the current global crisis may permanently alter the biosphere’s taxonomic composition by changing the rules of evolution.
Climate, Critters, and Cetaceans: Cenozoic Drivers of the Evolution of Modern Whales
Based on a comprehensive diversity data set, much of observed cetacean paleodiversity can indeed be explained by diatom diversity in conjunction with variations in climate as indicated by oxygen stable isotope records (δ18O).
