Likelihood analyses of 1176 fossil assemblages of marine organisms from Phanerozoic (i.e., Cambrian to Recent) assemblages indicate a shift in typical relative-abundance distributions after the Paleozoic. Ecological theory associated with these abundance distributions implies that complex ecosystems are far more common among Meso-Cenozoic assemblages than among the Paleozoic assemblages that preceded them. This transition coincides not with any major change in the way fossils are preserved or… Expand
Assessing the role of abundance in marine bivalve extinction over the post-Paleozoic
TLDR
It is shown that abundance was an important factor in the extinction dynamics of marine bivalve genera over the post-Paleozoic, with rare and abundant genera exhibiting rates elevated over those of genera of moderate abundance. Expand
Differential responses of marine communities to natural and anthropogenic changes
TLDR
The recent ecosystem shift stands in contrast to the long-term endurance of interglacial communities in face of climate-driven environmental changes. Expand
Trophic network models explain instability of Early Triassic terrestrial communities
TLDR
A trophic network model is used that combines topological and dynamic approaches to simulate disruptions of primary productivity in palaeocommunities of the Karoo Basin, South Africa, and shows that while Permian communities bear no evidence of being especially susceptible to extinction, Early Triassic communities appear to have been inherently less stable.

Phanerozoic Trends in the Global Diversity of Marine Invertebrates
It has previously been thought that there was a steep Cretaceous and Cenozoic radiation of marine invertebrates. This pattern can be replicated with a new data set of fossil occurrences representingExpand
Evolutionary models in the Early Triassic marine realm
Abstract The relative influences of extrinsic compared to intrinsic drivers of evolutionary change have long been theorized and debated in the fossil record. Ecological recoveries from massExpand
Graptolite community responses to global climate change and the Late Ordovician mass extinction
TLDR
The results indicate that the species abundance structure of planktic communities may be a leading indicator of the effects of climate change on biodiversity and a more sensitive gauge of those effects than taxonomic diversity change alone. Expand
Escargots through time: an energetic comparison of marine gastropod assemblages before and after the Mesozoic Marine Revolution
TLDR
Estimates of mean per capita metabolic rates of tropical to subtropical assemblages of shallow-marine gastropods both before and after the Mesozoic Marine Revolution support the hypothesis that benthic energy budgets increased during the MMR, possibly in response to rising primary productivity. Expand
Holocene shifts in the assembly of plant and animal communities implicate human impacts
TLDR
Evaluating changes in plant and animal community organization over geological time by quantifying the co-occurrence structure of 359,896 unique taxon pairs in 80 assemblages spanning the past 300 million years suggests that the rules governing the assembly of communities have been changed by human activity.

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
Diversity and palaeoecology of a highly diverse Late Triassic marine biota from the Cassian Formation of north Italy
A sample of marine invertebrates from the Late Triassic Cassian Formation (north Italy) yielded one of the most diverse Early Mesozoic fossil assemblages ever reported (c. 170 species). TheExpand

Substrate affinity and diversity dynamics of Paleozoic marine animals
Abstract Short-term fluctuations in the diversification rate of Paleozoic marine animal genera are more strongly correlated with extinction-rate variation than with origination-rate variation.Expand
Dynamic response of Permian brachiopod communities to long-term environmental change
TLDR
This work uses a maximum-likelihood approach to show that brachiopod abundance distributions from four temporally distinct ecological landscapes from the Glass Mountains, Texas (of the Permian period), exhibit significant differences, and suggests that sea level fluctuations spanning about 10 Myr altered the degrees of isolation and exchange among local communities within these ecological landscapes.

Increase in evenness and sampled alpha diversity through the Phanerozoic: Comparison of early Paleozoic and Cenozoic marine fossil assemblages
TLDR
Trends in the relative abundance of taxa are examined and the results indicate that the evenness of fossil samples increased through the Phanerozoic, largely owing to a decrease in the Relative abundance of the most common taxa. Expand
Restructuring in benthic level-bottom shallow marine communities due to prolonged environmental stress following the end-Permian mass extinction
Abstract Because the end-Permian mass extinction was the largest mass extinction since the Cambrian, numerous studies have focused on taxonomic changes and patterns immediately before and after theExpand
ASSESSING THE ECOLOGICAL DOMINANCE OF PHANEROZOIC MARINE INVERTEBRATES
TLDR
Large-scale dominance patterns often approximately matched those inferred from diversity trends; however, there are also times when dominance was decoupled from diversity, indicating that further investigation of ecological dominance will provide additional insights into ecological influences on the Phanerozoic history of life. Expand
Ecological, taxonomic, and taphonomic components of the post-Paleozoic increase in sample-level species diversity of marine benthos
TLDR
The study demonstrates that the post-Paleozoic trends in the sample-level diversity, ecology, and taxonomic structure of common taxa can be replicated across multiple studies, and suggests that the diversity increase estimated here is much less prominent than suggested by many previous analyses.

Anatomical and ecological constraints on Phanerozoic animal diversity in the marine realm
We grouped the fossil records of marine animal genera into suites defined by function and physiology. The stratigraphic coherence of the resulting diversity history indicates the importance ofExpand
Preservation of Species Abundance in Marine Death Assemblages
TLDR
Statistical meta-analysis of 85 marine molluscan data sets indicates that, although sensitive to sieve mesh-size and environment, time-averaged death assemblages retain a strong signal of species' original rank orders. Expand
