This study provides a comprehensive and quantitative estimate of how global temperatures
have changed during the last 540 million years. It combines paleotemperature …

Abstract The Ediacaran-Cambrian transition, which incorporates the radiation of animals,
lacks a robust global temporal and spatial framework, resulting in major uncertainty in the …

Abstract Distinctive uppermost Ediacaran–Ordovician rocks (Avalonian overstep sequence)
were key in definition of Avalonia, which comprises large areas of the NE Appalachians and …

The transition from the terminal Ediacaran to early Cambrian (ca. 550–530 Ma) witnessed
both the decline of Ediacaran-type soft-bodied and skeletal biota and the rapid …

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

While it remains uncertain whether excursions in the stable carbon isotopic composition of
Ediacaran marine carbonate (δ 13 C carb) represent globally synchronous events (or a …

Marine ecosystems with a diverse range of animal groups became established during the
early Cambrian (~ 541 to~ 509 Ma). However, Earth's environmental parameters and …

Hadimopanella knappologica, Archaeopetasus typicus, and first descriptions of
Hadimopanella foveata Kouchinsky sp. nov. and Archaeopetasus pachybasalis Kouchinsky …

Whether metazoan diversification during the Cambrian Radiation was driven by increased
marine oxygenation remains highly debated. Repeated global oceanic oxygenation events …

The Avalonia microcontinent has diagnostic terminal Ediacaran–Ordovician
lithostratigraphy, depositional sequence architecture, and igneous activity that extends for …
