<span>MOBS</span> 1.0: A Database of Interspecific Variation in Marine Organismal Body Sizes Open
Motivation Body size is a fundamental trait influencing an organism's life history, ecology, physiology and evolutionary dynamics. While extensive body‐size databases exist for terrestrial vertebrates, equivalent datasets for marine animal…

Physiology and climate change explain unusually high similarity across marine communities after end-Permian mass extinction Open
Fossil assemblages exhibit a global depletion in taxonomic distinctiveness in the aftermath of the end-Permian mass extinction (~252 million years ago), but little is known about why. Here, we examine whether biotic homogenization can be e…

Navigating uncertainty in maximum body size in marine metazoans Open
Body size is a fundamental biological trait shaping ecological interactions, evolutionary processes, and our understanding of the structure and dynamics of marine communities on a global scale. Accurately defining a species' body size, des…

Reduced strength and increased variability of extinction selectivity during mass extinctions Open
Two of the traits most often observed to correlate with extinction risk in marine animals are geographical range and body size. However, the relative effects of these two traits on extinction risk have not been investigated systematically …

Hyperthermal events have a greater effect on body size origination selectivity than extinction Open
Ancient hyperthermal events in Earth’s history are ideal to isolate the evolutionary consequences of climate change and other environmental factors from other anthropogenic influences. A key biological trait hypothesized to be sensit…

History of Native American land and natural resource policy in the United States: impacts on the field of paleontology Open
We highlight the historical and contemporary policies that govern paleontological research on federally recognized Native American lands. The United States has a long history of fossil dispossession from Indigenous Peoples, and federal pol…

Selectivity of mass extinctions: Patterns, processes, and future directions Open
A central question in the study of mass extinction is whether these events simply intensify background extinction processes and patterns versus change the driving mechanisms and associated patterns of selectivity. Over the past two decades…

Comparing the Latitudinal Ranges of Genera of Mollusca and Arthropoda Before and After the End-Permian Extinction Open
The end-Permian mass extinction event resulted in the loss of approximately 80% to 90% of marine animal species due to drastic changes in climate. Because warming was a major factor in the extinction, it has been theorized the organisms th…

Using Machine Learning Models and Logistic Regression Analyses to Develop a Comprehensive Understanding of Extinction Risk For Marine Animal Phyla Across the Paleozoic Open
Extinction within the Paleozoic era has been studied in the past, but there still lacks a comprehensive understanding of how extinction risk changed throughout it. Our research project aims to bridge this gap by exploring extinction risk i…

Mass extinctions alter extinction and origination dynamics with respect to body size Open
Whether mass extinctions and their associated recoveries represent an intensification of background extinction and origination dynamics versus a separate macroevolutionary regime remains a central debate in evolutionary biology. The previo…

Peer Review #1 of "Substrate type and palaeodepth do not affect the Middle Jurassic taxonomic diversity of crinoids (v0.1)" Open
Crinoids are largely considered as good indicators for determining environmental conditions.They are robust proxies for inferring changes in salinity and sedimentation rate and for inferring substrate type.Some crinoid groups (e.g., certai…

Our past creates our present: a brief overview of racism and colonialism in Western paleontology Open
As practitioners of a historical science, paleontologists and geoscientists are well versed in the idea that the ability to understand and to anticipate the future relies upon our collective knowledge of the past. Despite this understandin…
