It is well known that the diversity of life appears to fluctuate during the course of the Phanerozoic, the eon during which hard shells and skeletons left abundant fossils (0–542 million years ago). Here we show, using Sepkoski's compendium of the first and last stratigraphic appearances of 36,380 marine genera, a strong 62 ± 3-million-year cycle, which is particularly evident in the shorter-lived genera. The five great extinctions enumerated by Raup and Sepkoski may be an aspect of this cycle… Expand

Topics from this paper

A contribution to knowledge of the development of marine life during the Permian and Triassic through the analysis of life histories of genera
TLDR
The analysis of the development of abundant genera (using classes and orders) in 13 marine animal taxa reveals that all the taxa studied suffered the biggest change in their generic composition during these two periods precisely at the Permo-Triassic boundary. Expand
Biodiversity: Fossils make waves
TLDR
A 62-million-year cycle in biodiversity emerges from scrutiny of a marine-fossil database, but its causes remain mysterious and various models involving climate, environment, geological and astrophysical factors should provide testable predictions to help solve the mystery. Expand
Cyclicity in the fossil record mirrors rock outcrop area
TLDR
A significant correlation between observed genus-level diversity and the amount of marine sedimentary rock measured at a surface outcrop in Western Europe is demonstrated, suggesting that cyclicity originates from long-term changes in sedimentary depositional and erosional regimes. Expand
Phanerozoic Marine Biodiversity: A Fresh Look at Data, Methods, Patterns and Processes
Patterns of Phanerozoic global biodiversity continue to be a major focus of palaeobiological research. Recent advances have been fuelled by the establishment of the Paleobiology Database. This newExpand
THE SHAPE OF THE PHANEROZOIC MARINE PALAEODIVERSITY CURVE: HOW MUCH CAN BE PREDICTED FROM THE SEDIMENTARY ROCK RECORD OF WESTERN EUROPE?
Abstract:  Palaeodiversity curves are constructed from counts of fossils collected at outcrop and thus potentially biased by variation in the rock record, specifically by the amount of sedimentaryExpand
16 Patterns of Diversification and Extinction
The history of life on Earth, from the earliest microscopic cells to the modern world populated by the rich variety of animals, plants, fungi, and microbes, is more than 3,500 Myr long. DocumentingExpand
PHANEROZOIC BIODIVERSITY MASS EXTINCTIONS
TLDR
A review of different methods of tabulating data from the Sepkoski database reveals 18 intervals during the Phanerozoic have peaks of both magnitude and rate of extinction that appear in each tabulating scheme, demonstrating that mass extinctions are not a homogeneous group of events. Expand
Causes and prime causes of mass biotic extinctions in the phanerozoic
925 Changes of various scales in biotic communities determined by environmental reorganizations provide grounds for defining geological periods. Transitions between geological periods are marked byExpand
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. Expand
Evolution of the Mesozoic oceanic biota: Response to abiotic factors
An analysis of the biota evolution during the Mesozoic in response to abiotic factors shows that the most important among them are the climate, sea-level position, dynamics and structure of the waterExpand

The nature of the fossil record
The fossil record, like the stratigraphical record, is thought to be episodic with long periods of quiescence separated by short periods of explosive evolution, expropriations and extinctions.Expand
The Impact of the Pull of the Recent on the History of Marine Diversity
TLDR
The Pull of the Recent accounts for only 5% of the Cenozoic increase in bivalve diversity, a major component of the marine record, suggesting that the diversity increase is likely to be a genuine biological pattern. Expand
Mass Extinctions in the Marine Fossil Record
A new compilation of fossil data on invertebrate and vertebrate families indicates that four mass extinctions in the marine realm are statistically distinct from background extinction levels. TheseExpand

TLDR
A growing body of evidence suggests that macroevolutionary processes effecting biotic transitions during background times were not fundamentally different from those operating during mass extinctions. Expand

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.
