A fundamental contribution of paleobiology to macroevolutionary theory has been the illumination of deep time patterns of diversification. However, recent work has suggested that taxonomic diversity counts taken from the fossil record may be strongly biased by uneven spatiotemporal sampling. Although morphological diversity (disparity) is also frequently used to examine evolutionary radiations, no empirical work has yet addressed how disparity might be affected by uneven fossil record sampling… 
Do different disparity proxies converge on a common signal? Insights from the cranial morphometrics and evolutionary history of Pterosauria (Diapsida: Archosauria)
TLDR
Pterosaurs provide an exemplar case demonstrating that different proxies for morphological form can converge on the same disparity signal, which is encouraging because often only one such proxy is available for extinct clades represented by fossils.
Does exceptional preservation distort our view of disparity in the fossil record?
TLDR
It is shown here that lagerstätten impact the disparity of ichthyosaurs, Mesozoic marine reptiles, by preserving higher diversity and more complete specimens, and suggests that uneven sampling presents issues for the view of disparity in the fossil record, but that this is also dependent on the methodology used.
An analysis of pterosaurian biogeography: implications for the evolutionary history and fossil record quality of the first flying vertebrates
TLDR
A novel model is proposed to explain pterosaurian distributions: pterosaurs underwent a series of ‘sweep-stakes’ dispersal events (across oceanic barriers in most cases), resulting in the founding of sympatric clusters of taxa.
Still slow, but even steadier: an update on the evolution of turtle cranial disparity interpolating shapes along branches
TLDR
The impact of topological and temporal uncertainty is explored, demonstrating that the Miocene dip, indeed, is a sampling artefact and all remaining conclusions could be more or less supported, including an apparent correlation with global biogeographic events, a minor correlation between cranial disparity and global temperature, and resilience across the K/T extinction event.
Journeys through discrete‐character morphospace: synthesizing phylogeny, tempo, and disparity
Palaeontologists have long employed discrete categorical data to capture morphological variation in fossil species, using the resulting character–taxon matrices to measure evolutionary tempo, infer
Discrete and continuous character-based disparity analyses converge to the same macroevolutionary signal: a case study from captorhinids
TLDR
The first comprehensive comparison of diversity and disparity of captorhinids, a group of basal amniotes that is important for understanding the early evolution of high-fiber herbivory, is presented.
Morphospaces and Databases: Diatom Diversification through Time
The diversity of diatom form inspired Art Nouveau designers, an interest renewed by recent advances in biomimetic design. The fossil record provides two windows on the diversification history of
Morphospaces and Databases: Diatom Diversification through Time
TLDR
An early exploration of diatom morphospace suggests that fossil forms should be considered alongside extant diatoms, and whether a literal reading of the fossil record or the use of subsampling algorithms is preferred is preferred.
Phylogeny, Macroevolutionary Trends and Historical Biogeography of Sloths: Insights From a Bayesian Morphological Clock Analysis.
TLDR
The phylogeny obtained supports the existence of the commonly recognized clades for the group and includes several recently described genera of sloths into an assembled morphological data supermatrix and applies Bayesian inference to 64 sloth genera.

Testing the effect of the rock record on diversity: a multidisciplinary approach to elucidating the generic richness of sauropodomorph dinosaurs through time
TLDR
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.
Mesozoic marine tetrapod diversity: mass extinctions and temporal heterogeneity in geological megabiases affecting vertebrates
TLDR
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.

TLDR
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.

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.
The shape of pterosaur evolution: evidence from the fossil record
TLDR
Pterosaur morphological diversification is, however, strongly age biased: rarefaction analysis shows that peaks of diversity occur in the Late Jurassic and Early Cretaceous correlated with periods of increased limb disparity.

TLDR
A detailed examination of pterosaur diversity through time is presented, including both taxic and phylogenetically corrected diversity estimates and comparison of these estimates with a model describing temporal variation in the number of pTerosaur-bearing formations (a proxy for rock availability).
Paleoenvironmental patterns in the evolution of post-Paleozoic benthic marine invertebrates
TLDR
A paleoenvironmental framework for constructing time-environment histories for higher taxa that should be of general comparative utility, based on five environmental categories recognized by physical sedimentary and biostratinomic criteria is developed and is consistent with a broad array of intrinsic biological mechanisms.
