Paleontological research on predation has been expanding rapidly in scope, methods, and goals. The growing assortment of research strategies and goals has led to increasing differences in sampling…
Quantifying the Timing and Rate of Crustal Evolution: Global Compilation of Radiometrically Dated Detrital Zircon Grains
Multiple models (steady state, episodic, and early growth followed by crustal reworking) have been postulated to explain the evolution of Earth’s continental crust. An independent assessment of these…
A fossil record full of holes: The Phanerozoic history of drilling predation
The evolutionary history of drilling predation, despite a long and rich fossil record (Precambrian–Holocene), contains a 120 m.y. gap (Late Triassic–Early Cretaceous). Drilled bivalve and brachiopod…
Strong coupling of predation intensity and diversity in the Phanerozoic fossil record

A species-level database of predation intensity, as measured by the frequency of common predation traces, suggests that macroevolutionary and macroecological patterns share common causative mechanisms that may reflect either historical processes or sampling artifacts.
The Avalon Explosion: Evolution of Ediacara Morphospace
A comprehensive quantitative analysis of these fossils indicates that the oldest Ediacara assemblage—the Avalonassemblage (575 to 565 Ma)—already encompassed the full range of Ediacar morphospace.
Time-Averaging, Overcompleteness, and the Geological Record
- M. Kowalewski

Time-averaging makes events that happened at different times appear to be synchronous in the geological record. It can generate overcompleteness by concentrating objects (e.g., fossils, clasts) from…
High-resolution estimates of temporal mixing within shell beds: the evils and virtues of time-averaging
This study quantifies the fine structure of time-averaging by using large samples of dated shells collected from within individual strata, finding that shell beds can provide a complete, high-resolution record, and thus offer exceptional insights into the environmental and climatic changes of the last 40 thousand years.
Two-phase increase in the maximum size of life over 3.5 billion years reflects biological innovation and environmental opportunity

This period-level compilation of the largest known fossil organisms demonstrates that maximum size increased by 16 orders of magnitude since life first appeared in the fossil record.
Stable isotope (δ18O, δ13C, and δD) signatures of recent terrestrial communities from a low-latitude, oceanic setting: Endemic land snails, plants, rain, and carbonate sediments from the eastern…
Spatial and Environmental Variation in the Fossil Record of Drilling Predation: A Case Study from the Miocene of Central Europe
Abstract Drilling predation presents a rare opportunity to quantify ecological interactions in the fossil record. Most large-scale studies have focused on temporal rather than spatial patterns.…
