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

Biotic activities are involved in almost all sedimentation processes throughout the
evolutionary history of life on our planet. However, deep-time organism-induced …

Earth's persistent habitability since the Archean remains poorly understood. Using an
oxygen isotope ensemble approach—comprising shale, iron oxide, carbonate, silica, and …

Paleotemperature proxy data form the cornerstone of paleoclimate research and are integral
to understanding the evolution of the Earth system across the Phanerozoic Eon. Here, we …

Abstract The Ordovician of Scandinavia (ie Denmark, Norway and Sweden) has been
investigated for over two centuries and, through time, various chronostratigraphic schemes …

Abstract During the Middle Ordovician, the Great Ordovician Biodiversification Event (GOBE)
saw an accelerated diversification pulse in the marine metazoan richness, which has 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 …

Oceanic upwelling is an important process in ocean cycling and has implications for climate
change and ocean productivity. During the Late Ordovician to early Silurian (O/S) transition …

Middle Ordovician iron ooids in the Upper Yangtze region of South China are composed
mainly of hematite and/or chamosite, found in mixed siliciclastic and carbonate successions …

The end Ordovician mass extinction (EOME) was the second most severe biotic crisis in
Phanerozoic, and has been widely linked to a major glaciation. However, robust …
