A comparison is made between compilations of times of origination and extinction of fossil marine animal families published in 1982 and 1992. As a result of ten years of library research, half of the information in the compendia has changed: families have been added and deleted, low-resolution stratigraphic data have been improved, and intervals of origination and extinction have been altered. Despite these changes, apparent macroevolutionary patterns for the entire marine fauna have remained…

Extinctions in the fossil record

Approaches to extinction analysis and prediction based on morphological variety or biodisparity should be explored as an adjunct or alternative to taxon inventories or phylogenetic metrics.

Data on rock outcrop area compiled for post-Palaeozoic sediments from Western Europe at stage level are presented and show a strongly cyclical pattern corresponding to first- and second-order sequence stratigraphical depositional cycles.

Abstract Short-term variations in rates of taxonomic extinction and origination in the fossil record may be the result of true changes in rates of turnover, variable rates of fossil preservation, or

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 new

The Fossil Record of Early Tetrapods: Worker Effort and the End-Permian Mass Extinction

It is important to understand the quality of the fossil record of early tetrapods (Tetrapoda, minus Lissamphibia and Amniota) because of their key role in the transition of vertebrates from water to

Successive approximations of diversity curves: Ten more years in the library

Traditional paleontological diversity curves are based on tallies of all taxa appearing in formally defined time units. These tallies are thought to be robust to further data collection. Thus, they

The ark was full! Constant to declining Cenozoic shallow marine biodiversity on an isolated midlatitude continent

Abstract In recent years several authors have questioned the reality of a widely accepted and apparently large increase in marine biodiversity through the Cenozoic. Here we use collection-level

A factor analytic description of the Phanerozoic marine fossil record

  • J. Sepkoski
  • Geography, Environmental Science
  • 1981
Data on numbers of marine families within 91 metazoan classes known from the Phanerozoic fossil record are analyzed. The distribution of the 2800 fossil families among the classes is very uneven,

Asymmetrical patterns of origination and extinction in higher taxa.

Analysis of Sepkoski's compendium of fossil marine families shows that declining pace of origination is an important controlling factor in long term taxic evolution, and confirms Van Valen's (1985a) suggestion that extinction behaves largely as a stationary process.

Periodicity in Extinction: The Role of Systematics

The case for periodicity in extinction, with a mass extinction every 26 x 106 yr since the mid—Permian, rests on analyses of the fossil record of marine families and genera, and the proportion of the data reflecting plausible extinctions is much lower among genera than among families.

This compendium is a new edition of the 1982 publication, correcting errors and presenting greater stratigraphic resolution and more current ideas about acceptable families and their classification.

The Geologic History of Diversity

A spirited debate occurred amongst the founders of geology over the geologic history of diversity (44, 104). Lyell (79) and Agassiz (1), among other adherents to strict uniformitarianism, maintained

Is the periodicity of extinctions a taxonomic artefact?

The evidence that extinctions since the mid-Permian show periodicity of ˜26 million years rests primarily on the stratigraphic ranges of marine families. We have checked the echinoderm and fish

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. These

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.

Confidence intervals on stratigraphic ranges

Observed stratigraphic ranges almost always underestimate true longevities. Strauss and Sadler (1987, 1989) provide a method for calculating confidence intervals on the endpoints of local

Phanerozoic trends in background extinction: Consequence of an aging fauna

If the probability of extinction for a family decreases through its own history, then overall changes in background-extinction rate are a function of a changing familial age distribution, and in geologic stages where there is a preponderance of young families, extinction rates can be predicted to be higher than in times where there are a plethora of older families.
