A possible role for stochastic radiation events in the systematic disparity between molecular and fossil dates
Adrian L. Melott
Major discrepancies have been noted for some time between fossil ages and molecular divergence dates for a variety of taxa. Recently, systematic trends within avian clades have bee…
Analysis of periodicity of extinction using the 2012 geological time scale
Adrian L. Melott, Richard K. Bambach
Analysis of two independent data sets with increased taxonomic resolution (genera rather than families) using the revised 2012 time scale reveals that an extinction periodicity fir…
A ubiquitous ~62 Myr periodic fluctuation superimposed on general trends in fossil biodiversity: II, Evolutionary dynamics associated with periodic fluctuation in marine diversity
Adrian L. Melott, Richard K. Bambach
We investigate evolutionary dynamics related to periodicity fossil biodiversity. Coherent periodic fluctuation in origination/extinction of marine genera that survive <45 million y…
A ubiquitous ~62-Myr periodic fluctuation superimposed on general trends in fossil biodiversity. I. Documentation
Adrian L. Melott, Richard K. Bambach
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 cycles in the history of life: Periodic biodiversity in the Paleobiology Database
Adrian L. Melott
Time series analysis of fossil biodiversity of marine invertebrates in the Paleobiology Database (PBDB) shows a significant periodicity at approximately 63 My, in agreement with pr…
Considering the Case for Biodiversity Cycles: Reexamining the Evidence for Periodicity in the Fossil Record
Bruce S. Lieberman, Adrian L. Melott
Medvedev and Melott (2007) have suggested that periodicity in fossil biodiversity may be induced by cosmic rays which vary as the Solar System oscillates normal to the galactic dis…
Bone Cancer Rates in Dinosaurs Compared with Modern Vertebrates
L. C. Natarajan, A. L. Melott, B. M. Rothschild +1
Data on the prevalence of bone cancer in dinosaurs is available from past radiological examination of preserved bones. We statistically test this data for consistency with rates ex…
