Cambrian Period | Definition, Plants, & Animals | Britannica
2025年1月11日 · Climate studies suggest that Cambrian temperatures were the norm for most of the Phanerozoic Eon (the last 538.8 million years), and these were exceeded only by a brief increase during the Permian Period (298.9 million to 251.9 million years ago) near the …
Cambrian - Wikipedia
The Cambrian was a time of greenhouse climate conditions, with high levels of atmospheric carbon dioxide and low levels of oxygen in the atmosphere and seas. Upwellings of anoxic deep ocean waters into shallow marine environments led to extinction events, whilst periods of raised oxygenation led to increased biodiversity .

2012年10月28日 · Globally, the Cambrian was a time of warm climate, while exhibiting strong provincialism among its fauna. Tectonically the Cambrian saw the opening of the Iapetus Ocean and the separation of the Launtentia, Baltica and Siberia plates (see …
Global climate, sea level cycles, and biotic events in the Cambrian Period
2015年3月1日 · A number of interrelated, cyclic, physical, chemical, and biotic effects during the Cambrian Period produced distinctive, time-specific global patterns of facies. These changes include abrupt episodes of sea level rise and incursion of cooler water onto the shelves of Cambrian continents.

The environment also became more hospitable, with a warming climate and rising sea levels flooding low-lying landmasses to create shallow, marine habitats ideal for spawning new life-forms.
An early Cambrian greenhouse climate | Science Advances - AAAS
Our results support an early Cambrian greenhouse climate comparable to those of the late Mesozoic and early Cenozoic, offering a framework for exploring the interplay between biotic and environmental controls on Cambrian animal diversification.
