Mass extinctions are often followed by intervals in which taxa disappear from the fossil record only to reappear again later. This ‘Lazarus effect’ is often attributed to a poor-quality fossil record or migration to refuges. Testing these alternatives, with examples from the end Permian and late Triassic extinctions, reveals that there is no link with the abundance of fossiliferous sites and the proportion of Lazarus taxa nor are missing taxa encountered in potential refuges. Therefore, the… Expand

Discussion on Lazarus taxa and fossil abundance at times of biotic crisis Journal, Vol. 156, 1999, pp. 453–456
R. J. Twitchett writes: Palaeontologists grudgingly accept that the fossil record of most taxa is very patchy and incomplete. A particular taxon will appear in the fossil record, and then disappearExpand
Lazarus taxa, refugia and relict faunas: evidence from graptolites
Mass extinctions are survived by a small number of evolutionary lineages, which give rise to the increase in biodiversity during the recovery phase; and by asmall number of species which survived in geographically small, isolated refugia, perhaps marginal to the main environment in crisis. Expand
Incompleteness of the Permian–Triassic fossil record: a consequence of productivity decline?
Analysis of published data shows that, for most animal groups, the fossil record in the immediate aftermath of the end-Permian biotic crisis is less complete than during the Late Permian or MiddleExpand
Life in the end-Permian dead zone
The significant time lag between terrestrial ecosystem collapse and selective extinction among characteristic Late Permian plants is documented, and the time-delayed, end-Permian plant extinctions resemble modeled “extinction debt” responses of multispecies metapopulations to progressive habitat destruction.

Permian–Triassic evolution of the Bivalvia: Extinction-recovery patterns linked to ecologic and taxonomic selectivity
There was no significant difference in proportional extinction/origination rates between infaunal and epifaunal taxa at the genus and family levels through the entire P–Tr transition, implying the absence of ecological selectivity, a conclusion that differs from some previous studies. Expand
Mesozoic marine fossil diversity and mass extinctions : an experience with the middle XIX century paleontological data
The recalculation of the paleontological data of A. dʼORBIGNY on the marine fossils distribution within the Mesozoic stages found that fossils diversity changes constrained with the 150 years old data seem to be enough similar to ones calculated with the recent data. Expand
Chapter 11 fossil preservation during the aftermath of the end-permian mass extinction: taphonomic processes and palaeoecological signals
Abstract A high number of Lazarus taxa and an alleged rarity of silicified faunas during the Early Triassic have been interpretedpreviously as indication that the fossil record following theExpand
Mass Extinctions and Changing Taphonomic Processes
The biotic crisis of the Middle Permian through Early Triassic is unmatched in the Phanerozoic in terms of taxonomic diversity losses and paleoecological reorganization. However, the potentialExpand
The Sixth Extinction Crisis Loss of Animal Populations and Species
There is an explosion of descriptions of new species even in previously "well-known" groups such as mammals, suggesting that previous estimates of the magnitude of biodiversity may be too low. Expand
The Lilliput effect in the aftermath of the end-Permian extinction event
Early Triassic animal body fossils and trace fossils are small relative to those in older and younger intervals. Size decreases sharply through the end-Permian extinction event and Permian/TriassicExpand


Mass Extinctions and Their Aftermath
In this text the demise of the dinosaurs is put into the proper context of other extinction events and all proposed extinction mechanisms - climate change, meteorite impact, volcanisms - are critically assessed. Expand
Why was there a delayed radiation after the end‐Palaeozoic extinctions?
Data from widespread dysaerobic facies, carbon/sulphur ratios and cerium anomalies suggest that the early Triassic was a time when anoxic conditions spread widely over epicontinental seas. TheseExpand
The effect of random range truncations on patterns of evolution in the fossil record
Recent advances in biostratigraphic-gap analysis provide models for the distribution of gap lengths between fossil occurrence horizons and provide methods to place confidence intervals on local taxon ranges and remove the biases caused by artificial range truncations. Expand
The importance of crisis progenitors in recovery from mass extinction
Abstract Progenitor taxa are defined as species or lineages which arise, commonly through punctuated or macroevolutionary processes, during the main phases of a mass extinction interval, and whichExpand

The time range and proportional distributions of Permian brachiopod families are summarized for the Permian Period. The ‘imperfection’ of the record is calculated from the apparent absences ofExpand
More than one event in the late Triassic mass extinction
The recent hypothesis that mass extinctions are discrete phenomena that have occurred with great regularity during the history of life1,2 is testable in several ways. Two essential elements of theExpand

  • The Quarterly Review of Biology

There is no evidence that either thecodontians or dinosaur demonstrated their superiority over mammal-like reptiles in massive competitive take-overs in the latest Triassic, and explanations of dinosaur success based on the competitive superiority of their thermoregulation or locomotory capability are unnecessary.
