The Cambrian Explosion was a key event in the evolution of life on Earth. This event took place at a time when sea surface temperatures have been proposed to reach about 60 °C. Such high temperatures are clearly above the upper thermal limit of 38 °C for modern marine invertebrates ...
But the trends shown by brachiopods suggests a differing physiological response. Together, these dynamics created both the distinct evolutionary record of metazoan groups during the Cambrian Explosion and determined the nature of its termination.
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 established as a result of the CE, taxonomic increases during the GOBE were manifested at lower taxonomic levels. Assessing ...
Significantly, evidence from this interval infers an oxygenation event in the backdrop of the most rapid radiation stage (ca. 520 to 510 Ma) during the Cambrian explosion, confirming that oxygen availability was a crucial factor in accelerating the radiation of marine animals....
The Cambrian Explosion was a pivotal event in the history of life half a billion years ago with the sudden appearance of dozens of distinctive animal body plans. After this initial burst of innovation, the appearance of new body plans slowed to a halt. This pattern has puzzled and intrigued ...

The Ediacaran–Cambrian (E-C) transition witnessed dramatic tectonic, climatic, oceanic, and biological co-evolutions at the dawn of the 'Cambrian explosion'. Although glaciations were reported in some mid-high-latitude continents during this interval, large uncertainties remain concerning timing and ...
