Quantifying historical trends in the completeness of the fossil record and the contributing factors: an example using Aves

  title={Quantifying historical trends in the completeness of the fossil record and the contributing factors: an example using Aves},
  author={Daniel T. Ksepka and Clint A. Boyd},
Abstract Improvements in the perceived completeness of the fossil record may be driven both by new discoveries and by reinterpretation of known fossils, but disentangling the relative effects of these processes can be difficult. Here, we propose a new methodology for evaluating historical trends in the perceived completeness of the fossil record, demonstrate its implementation using the freely available software ASCC (version 4.0.0), and present an example using crown-group birds (Aves).

Ten more years of discovery: revisiting the quality of the sauropodomorph dinosaur fossil record
Spatiotemporal changes in fossil specimen completeness can bias our understanding of a group's evolutionary history. The quality of the sauropodomorph fossil record was assessed a decade ago, but the
Changes to the Fossil Record of Insects through Fifteen Years of Discovery
The first and last occurrences of hexapod families in the fossil record are compiled from publications up to end-2009, and changes suggest that some inferences about causal mechanisms in insect macroevolution are likely to differ as well.
Extant‐only comparative methods fail to recover the disparity preserved in the bird fossil record

By uniting morphological and phylogenetic data on 604 extant genera of birds with morphological data on 58 species of extinct birds from 50 million years ago, the “halfway point” of avian evolution, this work has been able to test how well extant‐only methods predict the diversity of fossil forms.
Preservation is predictable: quantifying the effect of taphonomic biases on ecological disparity in birds
Simulations are used to show how even weak taphonomic biases can distort estimates of richness, and render variance sensitive to sample size, and recommend that future large-scale studies include facies diversity along with metrics such as rock volume, or compare only sites with similar taphonomy histories.
The origins of crown group birds: molecules and fossils

It is shown how new sequence‐based phylogenies may shed light on the relationships of fossils with an unexpected character mosaic, and how such fossils can improve the understanding of character evolution in morphologically disparate avian taxa.
Taxonomic identification bias does not drive patterns of abundance and diversity in theropod dinosaurs
It is found that the patterns of differential species abundance and clade diversity are not a consequence of their relative diagnosability, and this suggests that patterns of relative abundance and diversity for theropods might be more representative of Mesozoic ecology than often considered.
A new time tree reveals Earth history’s imprint on the evolution of modern birds
P pervasive evidence is found that avian evolution has been influenced by plate tectonics and environmental change, two basic features of Earth’s dynamics.
Flying rocks and flying clocks: disparity in fossil and molecular dates for birds
Empirical patterns observed here suggest systemic overestimates for shallow nodes in existing molecular divergence dates for birds, and underlying biases that may drive these patterns are discussed.
Early Paleocene landbird supports rapid phylogenetic and morphological diversification of crown birds after the K–Pg mass extinction
The discovery of Tsidiiyazhi pushes the minimum divergence ages of as many as nine additional major neoavian lineages into the earliest Paleocene, compressing the duration of the proposed explosive post–K–Pg radiation of modern birds into a very narrow temporal window parallel to that suggested for placental mammals.
Low ecological disparity in Early Cretaceous birds
Comparisons of the Jehol functional diversity with modern and subfossil avian assemblages show that taphonomic bias alone cannot explain the ecomorphological impoverishment, and evolutionary simulations suggest that the constrained ecological diversity of the Early Cretaceous pygostylians is consistent with what is expected from a relatively young radiation.


Quality of the fossil record through time
It is shown that new assessment methods, in which the order of fossils in the rocks (stratigraphy) is compared with the order inherent in evolutionary trees (phylogeny), provide a more convincing analytical tool: stratigraphy and phylogeny offer independent data on history.
Absolute measures of the completeness of the fossil record
Quantitative, widely applicable absolute measures of completeness at two taxonomic levels for a broader sample of higher taxa of marine animals than has previously been available are presented and it is found that completeness is rather high for many animal groups.
The quality of the fossil record of Mesozoic birds
A dataset comprising all known fossil taxa is presented, suggesting that the broad outlines of early avian evolution are consistently represented: no stage in the Mesozoic is characterized by an overabundance of scrappy fossils compared with more complete specimens.
The completeness of the continental fossil record and its impact on patterns of diversification
It is found that, although continental fossil richness is correlated with the amount of terrestrial clastic sediment available for sampling, the exponential diversification curve of continental metazoans is unlikely to be an artifact of this rock bias.
Uncertainty in the age of fossils and the stratigraphic fit to phylogenies.
The effect of age uncertainty on measures of stratigraphic fit to phylogenies is explored here for two indices based on the extension of ghost lineages (MSM* and GER), with a solution based on randomization of the ages of terminal taxa resulting in a range of possible values.
The Fossil Record and Evolution: Comparing Cladistic and Paleontologic Evidence for Vertebrate History
A survey of a sample of taxa shows a tendency for positive correlation between age and clade rank and, hence, a degree of correspondence between phylogenetic pattern and the paleontologic record.
Testing the quality of the fossil record: Paleontological knowledge is improving
The value of the fossil record in giving a clear account of evolutionary history has been questioned because of its incompleteness. New evidence suggests, however, that this is not an overwhelming
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
The modified gap excess ratio (GER*) and the stratigraphic congruence of dinosaur phylogenies.
This work investigates congruence for 19 independent, published cladograms of major dinosaur groups and reports exceptional agreement between the phylogenetic and stratigraphic patterns, evidenced by sums of ghost ranges near the theoretical minima.
Fossil gap analysis supports early Tertiary origin of trophically diverse avian orders
The quality of the fossil record is consistent with the classical view that trophically diverse extant bird orders arose and diversified rapidly following the widespread extinction of other terrestrial groups at the K-T boundary.
