In the geological sciences it has only recently been recognized how important the process of
impact cratering is on a planetary scale, where it is commonly the most important surface …

This paper provides an overview of the contentious issue of global megafaunal extinctions in
the Late Quaternary. The main proposed causes are 'overkill', environmental change or a …

This volume is a major revision and expansion of Taylor's seminal book Radiocarbon
Dating: An Archaeological Perspective. It covers the major advances and accomplishments …

We review and synthesize the geologic record that constrains the sources of sea level rise
and freshwater discharge to the global oceans associated with retreat of ice sheets during …

A series of publications purport to provide evidence that the Earth was subjected to an
extraterrestrial event or events at∼ 12.9 ka creating an environmental cataclysm and the …

More than 50 years of space and planetary exploration and concomitant studies of terrestrial
impact structures have demonstrated that impact cratering has been a fundamental process …

This accessible and engaging text explores the relationship between philosophy, science
and physical geography. It addresses an imbalance that exists in opinion, teaching and to a …

Airbursts/impacts by a fragmented comet or asteroid have been proposed at the Younger
Dryas onset (12.80±0.15 ka) based on identification of an assemblage of impact-related …

It has been proposed that fragments of an asteroid or comet impacted Earth, deposited silica-
and iron-rich microspherules and other proxies across several continents, and triggered the …

Abstract The Younger Dryas (YD) impact hypothesis posits that fragments of a large,
disintegrating asteroid/comet struck North America, South America, Europe, and western …
