Global diversity curves reflect more than just the number of taxa that have existed through time: they also mirror variation in the nature of the fossil record and the way the record is reported. These sampling effects are best quantified by assembling and analyzing large numbers of locality-specific biotic inventories. Here, we introduce a new database of this kind for the Phanerozoic fossil record of marine invertebrates. We apply four substantially distinct analytical methods that estimate… 
Phanerozoic Marine Biodiversity: A Fresh Look at Data, Methods, Patterns and Processes
Patterns of Phanerozoic global biodiversity continue to be a major focus of palaeobiological research. Recent advances have been fuelled by the establishment of the Paleobiology Database. This new
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
Dinosaur diversity and the rock record
TLDR
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.
Marine diversity through the Phanerozoic: problems and prospects

The fossil record provides direct evidence of how diversity has changed over time, but cannot be taken at face value. Diversity curves constructed from counting taxa in the rock record are seriously
Taxonomic structure of the fossil record is shaped by sampling bias.
TLDR
There is a two-stepped change in the ratio of species to genera over the last 150 myr, which argues against using raw species-to-genus ratios to infer biological processes without taking sampling into account and suggests that higher taxa cannot be taken as unbiased proxies for species diversity.
GEOGRAPHICAL, ENVIRONMENTAL AND INTRINSIC BIOTIC CONTROLS ON PHANEROZOIC MARINE DIVERSIFICATION
Abstract:  The Paleobiology Database now includes enough data on fossil collections to produce useful time series of geographical and environmental variables in addition to a robust global
The early evolution of synapsids, and the influence of sampling on their fossil record
TLDR
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.
Are global Phanerozoic marine diversity curves truly global? A study of the relationship between regional rock records and global Phanerozoic marine diversity
Abstract The consensus view that the amount of rock available for sampling does not significantly and systematically bias Phanerozoic marine diversity patterns has broken down. How changes in rock
The effects of taxonomic standardization on sampling-standardized estimates of historical diversity
TLDR
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.
Controlling for the species-area effect supports constrained long-term Mesozoic terrestrial vertebrate diversification
TLDR
It is shown that controlling for variance in geographic spread in the fossil record significantly impacts inferred patterns of diversity through time, and that an abrupt tripling of richness in the earliest Palaeogene suggests that this diversity equilibrium was reset following the K/Pg extinction.

Calibrating the Ordovician Radiation of marine life: implications for Phanerozoic diversity trends.
TLDR
A global-scale sample of fossil occurrences is analyzed that allows us to determine directly the effects of sample size on the calibration of what is generally thought to be among the most significant global biodiversity increases in the history of life: the Ordovician Radiation.

A kinetic model of Phanerozoic taxonomic diversity I. Analysis of marine orders
TLDR
This model appears to describe adequately the “explosive” diversification of known metazoan orders across the Precambrian-Cambrian Boundary, suggesting that no special event, other than the initial appearance of Metazoa, is necessary to explain this phenomenon.
New methods for quantifying macroevolutionary patterns and processes
TLDR
Data are presented showing that even diverse individual fossil collections merely yield a noisy version of the same pattern seen in the overall continental data set, suggesting that environmental perturbations do not have simple effects on the biota.
Constant extinction, constrained diversification, and uncoordinated stasis in North American mammals
TLDR
Tests for niche incumbency show that incumbency is widespread and mediated by the suppression of origination at high diversity levels in all groups, and against Vrba's turnover pulse hypothesis, mammalian diversity seems to be integrated at the highest possible taxonomic level, in opposition to the coordinated stasis concept of static guilds.
Marine Benthic Diversity: A Comparative Study
TLDR
A within-habitat analysis was made of the bivalve and polychaete components of soft-bottom marine faunas which differed in latitude, depth, temperature, and salinity, and it was indicated that species number is the more valid diversity measurement.
