Latest Cryogenian Stories
In a study published in the journal Geology, scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that the large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as 'Snowball Earth,' are unrelated to worldwide glacial events.
Researchers in Britain and Australia have discovered evidence that parts of the open ocean may have experienced a catastrophic global freeze some 700 million years ago, which nearly wiped out life on Earth.
Scientists have found fossils which suggest that animal life appeared on Earth millions of years earlier than previously thought.
For insight into what can happen when the Earth's carbon cycle is altered -- a cause and consequence of climate change -- scientists can look to an event that occurred some 720 million years ago.
Scientists find signs of 'snowball Earth' amidst early animal evolution.
Scientists announced on Wednesday the discovery of the earliest evidence of animal life to date.
The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
