Abstract We use Fourier analysis and related techniques to investigate the question of periodicities in fossil biodiversity. These techniques are able to identify cycles superimposed on the long-term trends of the Phanerozoic. We review prior results and analyze data previously reduced and published. Joint time-series analysis of various reductions of the Sepkoski Data, Paleobiology Database, and Fossil Record 2 indicate the same periodicity in biodiversity of marine animals at 62 Myr. We have… 
An ubiquitous ~62 Myr periodic fluctuation superimposed on general trends in fossil biodiversity
TLDR
A 62 Myr periodicity is superimposed on other longer-term trends in fossil biodiversity and a significant excess of 19 previously identified Phanerozoic mass extinctions occur on the declining phase of the 62 Myr cycle.
A ubiquitous ∼62-Myr periodic fluctuation superimposed on general trends in fossil biodiversity. II. Evolutionary dynamics associated with periodic fluctuation in marine diversity
TLDR
The presence of a periodic pattern in evolutionary dynamics of the more vulnerable “short-lived” component of the marine fauna demonstrates that a long-term periodic fluctuation in environmental conditions capable of affecting evolution in the marine realm characterizes the authors' planet's history.
Analysis of periodicity of extinction using the 2012 geological timescale
TLDR
Analysis of two independent data sets with increased taxonomic resolution using the revised 2012 timescale reveals that an extinction periodicity first detected by Raup and Sepkoski (1984) for only the post-Paleozoic actually runs through the entire Phanerozoic.
A ~60 Myr periodicity is common to marine-87Sr/86Sr, fossil biodiversity, and large-scale sedimentation: what does the periodicity reflect?
We find that the marine 87Sr/86Sr record shows a significant periodicity of 59.3 \pm 3 Myr. The 87Sr/86Sr record is 171{\deg} \pm 12{\deg}out of phase with a 62 (\pm 3) Myr periodicity previously
An ∼60-Million-Year Periodicity Is Common to Marine 87Sr/86Sr, Fossil Biodiversity, and Large-Scale Sedimentation: What Does the Periodicity Reflect?
TLDR
It is found that the marine 87Sr/86Sr record shows a significant periodicity that reflects the operation of a periodic “pulse of the earth” in large-scale earth processes, which may be linked to mantle or plate-tectonic events, possibly uplift, which affects the earth's climate and oceans and, thus, the geochemistry, sedimentation and biodiversity of the marine realm.
Timing and periodicity of Phanerozoic marine biodiversity and environmental change
TLDR
The results suggest that long timescale processes (e.g. plate kinematics) are the primary drivers of biodiversity, whilst processes with significant variability at shorter periods play a moderating role.
Limits to biodiversity cycles from a unified model of mass-extinction events

TLDR
It is shown that if there is a periodic extinction signal at all, it is much more likely to result from a combination of a comparatively weak periodic cause and various random factors.
Do Periodicities in Extinction—with Possible Astronomical Connections—Survive a Revision of the Geological Timescale?
TLDR
It is found that the spectral power in this period is somewhat increased, and persists at a narrow bandwidth, which supports the previous contention that the Nemesis hypothesis is untenable as an explanation for the periodicity of marine extinction rates.
Sea level regulated tetrapod diversity dynamics through the Jurassic/Cretaceous interval
TLDR
A rigorous subsampling approach is applied to a comprehensive tetrapod fossil occurrence data set to assess the group's macroevolutionary dynamics through the J/K transition, culminating in the extinction of several important clades and the ecological release and radiation of numerous modern tetrapOD groups.
Does the planetary dynamo go cycling on? Re-examining the evidence for cycles in magnetic reversal rate
Abstract The record of reversals of the geomagnetic field has played an integral role in the development of plate tectonic theory. Statistical analyses of the reversal record are aimed at detailing

Long-Term Cycles in the History of Life: Periodic Biodiversity in the Paleobiology Database
TLDR
Cross-spectral analysis of the two datasets finds that a 62 My periodicity coincides in phase by 1.6 My, equivalent to better than the errors in either measurement, which strongly argues for consideration of its reality in the fossil record.
Considering the Case for Biodiversity Cycles: Re-Examining the Evidence for Periodicity in the Fossil Record
TLDR
The signal is robust against variations in methods of analysis, and is based on fluctuations in the Paleozoic and a substantial part of the Mesozoic.
Self-similarity of extinction statistics in the fossil record
The dynamical processes underlying evolution over geological timescales remain unclear,. Analyses of time series of the fossil record have highlighted the possible signature of periodicity in mass

TLDR
The temporal distribution of the major extinctions over the past 250 million years has been investigated statistically using various forms of time series analysis and contains 12 extinction events that show a statistically significant periodicity.
Periodic extinction of families and genera.
TLDR
Time-series analysis of eight major episodes of biological extinction of marine families over the past 250 million years strongly suggests a 26-million-year periodicity, robust even when adjusted for simultaneous testing of many trial periods.
Cycles in fossil diversity
TLDR
A strong 62 ± 3-million-year cycle is shown, using Sepkoski's compendium of the first and last stratigraphic appearances of 36,380 marine genera, which is particularly evident in the shorter-lived genera.
Whilst This Planet Has Gone Cycling On: What Role for Periodic Astronomical Phenomena in Large-Scale Patterns in the History of Life?
TLDR
There is indeed some evidence that periodicity may be real, though of course more work is needed, and the significance of this for the understanding of evolution and the history of life is considered.
The completeness of the continental fossil record and its impact on patterns of diversification
TLDR
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.
Phanerozoic Trends in the Global Diversity of Marine Invertebrates
It has previously been thought that there was a steep Cretaceous and Cenozoic radiation of marine invertebrates. This pattern can be replicated with a new data set of fossil occurrences representing
