The vast majority of species that have ever lived went extinct sometime other than during
one of the great mass extinction events. In spite of this, mass extinctions are thought to have …

Extinction of species, and even clades, is a normal part of the macroevolutionary process.
However, several times in Earth history the rate of species and clade extinctions increased …

The history of Earth's biodiversity is punctuated episodically by mass extinctions. These are
characterized by major declines of taxon richness, but the accompanying ecological …

The fossil record provides striking case studies of biodiversity loss and global ecosystem
upheaval. Because of this, many studies have sought to assess the magnitude of the current …

Enigmatic catastrophic events, involving mass extinction of life forms, have been recorded
several times in the Earth history. In many cases, the causes and mechanisms of these …

A review of the literature shows that understanding of biotic restructuring following the
Permo-Triassic mass extinction (PTME) is typically based on only a few components of the …

Trace fossils have proven useful for studying the timing and process of biotic recovery after
the Permian–Triassic Mass Extinction (PTME). Recovery stages are defined by comparing …

Mass extinctions disrupt ecological communities. Although climate changes produce stress
in ecological communities, few paleobiological studies have systematically addressed the …

Ecologists and paleontologists alike are increasingly using the fossil record as a spatial data
set, in particular to study the dynamics and distribution of geographic range sizes among …

Despite several, sometimes prominent propagators, meteorite impact research had a long
period of peripheral status until the 1980s. Since then there has been an intensive search for …
