Latest Proterozoic Stories
Lee Rannals for redOrbit.com – Your Universe Online About 635 million years ago, our world was covered in ice during an event called "Snowball Earth," and new details written in the Proceedings of the National Academy of Sciences provide new insight on the duration of this event. According to the Snowball Earth hypothesis, an ice age brought on rapid changes in the atmospheric conditions on our planet, followed by a rapid greenhouse heat wave. This period may have given rise to...
redOrbit Staff & Wire Reports - Your Universe Online Mysterious multicellular fossils believed to be ancient sea creatures may actually be some of the earliest land-dwelling organisms, according to a paper published online on Wednesday in the journal Nature. The controversial hypothesis has been fiercely criticized, with some paleontologists flatly rejecting the idea, but if true, the finding would push back life's transition from sea to land by as much as 100 million years or more....

April Flowers for redOrbit.com - Your Universe Online Geochemists from the University of California, Riverside teamed up with an international team of scientists to uncover new evidence linking together extreme climate change, elevation of oxygen levels and early animal evolution. Scientists have long speculated that a dramatic rise in atmospheric oxygen levels was the trigger for early animal evolution. The direct cause-and-effect relationships between environmental and animal...

The April/May GSA Today science article is now online at www.geosociety.org/gsatoday/. In this issue, Simon Williams and colleagues from the Earthbyte Group of the School of Geosciences at the University of Sydney present GPlates, a powerful new method for analyzing geological and geophysical data sets within the context of tectonic reconstructions. GPlates is part of a new generation of plate reconstruction software that incorporates functionality familiar from GIS software with the added...
Paleontologists have discovered the oldest organism with a skeleton in Australia. The creature is called Coronacollina acula and is estimated to be between 550 and 560 million years old. Paleontologists estimate this animal is from the Ediacaran Period, before the diversification of organisms in the Cambrian Period. The study results appeared online February 14 in Geology. This important find could be the key to unlocking several questions about early life, evolution, and extinction....
All of Earth's continents, believed to have once been joined together as a supercontinent known as Pangaea, will be reunited as a single landmass near the North Pole within the next 50 million to 200 million years, researchers from Yale University claim in a new study. According to MSNBC Science Editor Alan Boyle, the Yale researchers, including geologist Ross Mitchell, used a computer model to determine the estimated location of the new supercontinent, which they have dubbed Amasia due to...

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...
The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...
The Archean (formerly Archaeozoic) is a geologic eon between the Hadean and Proterozoic eons. The Archean Eon begins at roughly 3.8 billion years ago (Ga) and ends at about 2.5 Ga. But unlike all other geological ages, which are based on stratigraphy, The Archean eon is defined chronometrically. The lower boundary of 3.8 Ga has also not been officially recognized by the International Commission on Stratigraphy. The name Archean is derived from the ancient Greek (Arkhe), meaning...
