We find that the marine 87Sr/86Sr record shows a significant periodicity of m.yr. The 87Sr/86Sr record is out of phase with a 62 (±3)-m.yr. periodicity previously reported in the record of marine animal diversity. These periodicities are close to 58 (±4)-m.yr. cycles found for the number of gap-bounded sedimentary carbonate packages of North America. We propose that these periodicities reflect the operation of a periodic “pulse of the earth” in large-scale earth processes. These may be linked… 
Periodicities in the emplacement of large igneous provinces through the Phanerozoic: Relations to ocean chemistry and marine biodiversity evolution
Abstract Large igneous provinces (LIPs) are considered a relevant cause for mass extinctions of marine life throughout Earth’s history. Their flood basalts and associated intrusions can cause
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
Ultra-high resolution multivariate record and multiscale causal analysis of Pridoli (late Silurian): Implications for global stratigraphy, turnover events, and climate-biota interactions
Abstract The upper Silurian, and especially Pridoli epoch is a critical interval for the understanding the evolution of Earth’s biota, since it witnessed series of powerful extinction events, global
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.
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.
Assessing the Influence of the Solar Orbit on Terrestrial Biodiversity
TLDR
It is difficult to give convincing positive conclusions of such a connection between solar motion and biodiversity variations on the Earth using current data, and various versions of the orbital model are not favored beyond simpler reference models.
Evidence of synchronous, decadal to billion year cycles in geological, genetic, and astronomical events
Studies on continuously improving records of geological, biological, and astronomical events and processes led to increased awareness of common cycles in the records. Here we enhance the analytical
Marine diversity in the geological record and its relationship to surviving bedrock area, lithofacies diversity, and original marine shelf area
Biological principles suggest that recorded species diversity should increase as sampled area and habitat diversity increase. However, the interactions between Earth system drivers of these physical
Is the Solar System's Galactic Motion Imprinted in the Phanerozoic Climate?
TLDR
It is proposed that the galactic motion left an imprint on the terrestrial climate record because of the effective average galactic density encountered by the solar system, which suggests the presence of a disk dark matter component.
Period-Tripling and Fractal Features in Multi-Billion Year Geological Records
Period-tripling is a common but rarely studied feature of natural processes. Its detection in long-term geological events is often restricted by poor preservation, inadequate time-resolution, and

A ubiquitous ~62-Myr periodic fluctuation superimposed on general trends in fossil biodiversity. I. Documentation
TLDR
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, but it is found that the signal strength decreases with time because of the accumulation of apparently “resistant” long-lived genera.

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.

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.
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.
