Taxon characteristics that promote survivorship through the Permian–Triassic interval: transition from the Paleozoic to the Mesozoic brachiopod fauna

  author={Lindsey R. Leighton and Chris L. Schneider},
Abstract Examination of organismal characteristics which promote survivorship through both background and mass extinctions may reveal general ecological principles potentially critical to modern conservation efforts. This study explores survivorship of brachiopods, a highly diverse and abundant Paleozoic clade, through the mid-Permian to mid-Triassic interval, which includes the greatest mass extinction in the history of metazoan life. This interval of time separates two of the major… 
Abundance and extinction in Ordovician–Silurian brachiopods, Cincinnati Arch, Ohio and Kentucky
Test the relationship between abundance and extinction among brachiopod genera within seven third-order depositional sequences spanning the Late Ordovician to Early Silurian (Katian–Aeronian) of the Cincinnati Arch and finds that abundance is not positively correlated with duration, further evidence that the Ordvician/Silurian extinction was not accompanied by a shift in the macroevolutionary selectivity regime.
Local and global abundance associated with extinction risk in late Paleozoic and early Mesozoic gastropods
It is found that global genus occurrence frequency is inversely associated with extinction risk in 15 of 16 stages examined, and survivorship patterns in late Paleozoic and early Mesozoic gastropods suggest that abundance has been a more important influence on extinction risk through the Phanerozoic than previously appreciated.
End-Permian Mass Extinction in the Oceans: An Ancient Analog for the Twenty-First Century?
The greatest loss of biodiversity in the history of animal life occurred at the end of the Permian Period (∼252 million years ago). This biotic catastrophe coincided with an interval of widespread
Precocious sexual dimorphism and the Lilliput effect in Neo‐Tethyan Ostracoda (Crustacea) through the Permian–Triassic boundary
Rare long‐time span Palaeocopida species, known throughout the entire Permian, document relatively long‐term evolution, including the size and growth rate modifications associated with the earlier appearance of carapace sexual dimorphism through time.
Marine Refugia Past, Present, and Future: Lessons from Ancient Geologic Crises for Modern Marine Ecosystem Conservation
Refugia are one means of species survivorship during a global crisis. As the Earth is facing a major crisis in the marine biosphere, the study of refugia through past extinctions and other global
Abstract: Although empirical testing of Cope's rule, the tendency for size to increase over time, has received significant attention in the last few decades, there is no consensus about the
A framework for the integrated analysis of the magnitude, selectivity, and biotic effects of extinction and origination
Abstract. The taxonomic and ecologic composition of Earth's biota has shifted dramatically through geologic time, with some clades going extinct while others diversified. Here, we derive a metric
Evidence for extinction selectivity throughout the marine invertebrate fossil record
A method for detecting random extinction is used to demonstrate that during both background and mass extinction times, extinction of marine invertebrate genera has been nonrandom with respect to species richness categories of genera.


Palaeozoic brachiopod extinctions, survival and recovery: patterns within the rhynchonelliformeans
The brachiopod‐dominated seabeds of the Palaeozoic were modified by a series of biotic extinctions and recoveries. The ecologic and taxonomic dynamics of the Cambrian and Paleozoic Evolutionary

Abstract A global database of gastropod sizes from the Permian through the Middle Triassic documents trends in gastropod shell size and permits tests of the suggestion that Early Triassic gastropods
Background and Mass Extinctions: The Alternation of Macroevolutionary Regimes
Comparison of evolutionary patterns among Late Cretaceous marine bivalves and gastropods during times of normal, background levels of extinction and during the end-Cretaceous mass extinction
Measuring Recurrence of Marine Biotic Gradients: A Case Study from the Pennsylvanian-Permian Midcontinent
Abstract The aim of this study was to determine whether biotic associations of Pennsylvanian-Permian brachiopods and bivalves from the northern Midcontinent differ in their degree of recurrence
Non‐selectivity in extinction of bivalves in the Late Cretaceous of the Atlantic and Gulf Coastal Plain of North America
Non‐parametric analysis revealed that there were no significant associations between any of these characteristics and survival across the Cretaceous‐Tertiary boundary and this lack of selectivity may be indicative of the severity of this extinction on bivalves.
Competitive displacement among post-Paleozoic cyclostome and cheilostome bryozoans
The microecological record of preserved competitive interactions between cyclostome and cheilostome bryozoans and the macroevolutionary record of global diversity are consistent in regard to competition as a significant influence on diversity histories of post-Paleozoic brysozoans.
Diversity and extinction patterns of permian brachiopoda of South China
The stratigraphical and geographical distribution of 851 brachiopod species from 216 genera and 65 families in the Permian of South China are analysed. It is revealed that the brachiopod diversity

Predictive purposes will involve factors such as differential extinction intensities among regions, clades, and functional groups, rules governing postextinction biotic interchanges and evolutionary dynamics, and analyses of the factors that cause taxa and evolutionary trends to continue unabated.
