Abstract The Ordovician Period records an extraordinary biodiversity increase known as the
Great Ordovician Biodiversification Event (GOBE), which coincided with a series of …

Ichnodisparity has been recently introduced as a concept to assess the variability of
morphologic plans in biogenic structures, revealing major innovations in body plan …

Abstract The Cambrian 'Explosion', located by many authors between 540 and 520 million
years ago (Ma), is considered to be an abrupt appearance in the fossil record of most animal …

The Ordovician Period (~ 485-444 Ma) was an interval of major, causally interconnected 15
changes in the Earth's biotic, climatic, and environmental systems. The diversity of marine …

The trace-fossil record provides a wealth of information to track the rise and early evolution
of animals. It comprises the activity of both hard-and soft-bodied organisms, is continuous …

A review of biodiversity curves of marine organisms indicates that, despite fluctuations in
amplitude (some large), a large-scale, long-term radiation of life took place during the early …

Contrasts between the Cambrian Explosion (CE) and the Great Ordovician Biodiversification
Event (GOBE) have long been recognized. Whereas the vast majority of body plans were …

Coral reef maintenance depends on the balance between constructive and destructive
forces. Constructive forces are mainly calcification and growth of corals and encrusting …

Trypanites is the most common macroboring with a global occurrence throughout the
Phanerozoic and is the eponym of the Trypanites ichnofacies. It has great value for the …

Tracking biodiversity changes based on body fossils through geologic time became one of
the main objectives of paleontology in the 1980s. Trace fossils represent an alternative …
