The beginning of the Phanerozoic saw two biological events that set the stage for all life that
was to come:(a) the Cambrian Explosion (the appearance of most marine invertebrate …

Astronomical insolation forcing is well established as the underlying metronome of
Quaternary ice ages and Cenozoic climate changes. Yet its effects on earlier eras …

Early Palaeozoic sites with soft-tissue preservation are predominantly found in Cambrian
rocks and tend to capture past tropical and temperate ecosystems. In this study, we describe …

ABSTRACT The Late Ordovician Mass Extinction was the earliest of the 'big'five extinction
events and the earliest to affect the trajectory of metazoan life. Two phases have been …

Abstract The Darriwilian (Middle Ordovician) is marked by a striking peak of the Great
Ordovician Biodiversification Event (GOBE) followed by an abrupt∼ 50% decline in …

Abstract The Early Cambrian Late Stage 2 to Stage 3 (526–514 Ma) was characterized by
the peak of the Cambrian Explosion and a large-scale global transgression that resulted in …

In the last decade, the Fossilized Birth–Death (FBD) process has yielded interesting clues
about the evolution of biodiversity through time. To facilitate such studies, we extend our …

The genus Calyxdendrum is here revised to include planktic dendroid graptolites from the
Ordovician (Tremadocian to Sandbian). The mass occurrence of Calyxdendrum amicabilis …

The Fezouata Shale Formation has dramatically impacted our understanding of Early
Ordovician marine ecosystems before the great Ordovician biodiversification event (GOBE) …

Abstract Computational Fluid Dynamic simulations (CFD) show that the Ordovician trilobite
Microparia speciosa had a high stability in the horizontal plane (parallel to the flow currents) …
