The MDICE is a globally recognized positive carbon isotope excursion event in the Ordovician. Historically, it has been primarily documented in δ 13 C carb data, with only scattered, incomplete ...
Back when the Earth was crawling with trilobites and other strange shelled creatures, our planet may have had a ring just like Saturn's. This ancient ring system is thought to have formed about 466 ...
The Earth has gone through many major events over the course of hundreds of millions of years. Some of the most significant are the six mass extinction events that have occurred. These are times when ...
A recent study claims that Earth may have once had a ring. The theory would explain the presence of an odd density of impact craters around the equator dating back to the Ordovician period. A ring ...
One of Earth's most consequential bursts of biodiversity—a 30-million-year period of explosive evolutionary changes spawning innumerable new species—may have the most modest of creatures to thank for ...
The Ordovician period offers a detailed window into early marine ecosystems and climatic transitions, with palynology and microfossil biostratigraphy serving as key tools in reconstructing these ...
The End-Ordovician Extinction was the first of the so-called ‘Big Five’ mass extinctions in the history of life on Earth - more than 80% of species in the oceans died out. But could you survive its ...
Today, only the largest planets in the solar system have rings, but a new study suggests Earth may have been a ringed planet in the distant past. Scientists studying the geology of the Ordovician ...
