Then 252 million years ago, something happened to cause the greatest mass extinction in Earth’s history. Over a few hundreds of thousands of years, the catastrophe killed off more than 95 percent of life on Earth. Scientists call it the Great Dying. It cleared the way for the rise of the age of dinosaurs. Scientists have debated the Great Dying’s cause, although, in recent years, many have begun to settle on the idea that volcanic eruptions were the primary cause. And now a new study – based on the discovery of mercury buried in ancient rocks – provides the strongest evidence yet that volcanoes did cause the Great Dying. Paleontologists with the University of Cincinnati and the China University of Geosciences said they found a spike in mercury in the geologic record at nearly a dozen sites around the world, providing what they called “persuasive evidence” that volcanic eruptions were to blame for this global cataclysm.
The idea is that volcanic eruptions ignited vast deposits of coal, releasing mercury vapor high into the atmosphere. Eventually, these scientists say, the mercury rained down into the marine sediments, and it’s the analysis of those ancient sediments today, now trapped in rock, that provides the basis for this new study.

Arctica or Arctida[1] was an ancient continent which formed approximately 2.565 billion years ago in the Neoarchean era. It was made of Archaean cratons, including the Siberian Craton, with its Anabar/Aldan shields in Siberia,[2] and the Slave, Wyoming, Superior, and North Atlantic cratons in North America.[3] Arctica was named by Rogers 1996 because the Arctic Ocean formed by the separation of the North American and Siberian cratons.[4] Russian geologists writing in English call the continent “Arctida” since it was given that name in 1987,[1] alternatively the Hyperborean craton,[5] in reference to the hyperboreans in Greek mythology.

Angaraland was named in the 1880s by Austrian geologist Eduard Suess who erroneously believed that in the Paleozoic there were two large continents in the Northern Hemisphere: “Atlantis”, North America connected to Europe by a peninsula (=Greenland and Iceland); and “Angara-land”, eastern Asia, named after the Angara River in Siberia.[3]

Except for the Virginia opossum, from North America, which is a metatherian, all post-Miocene mammals indigenous to Europe, Africa, Asia, and North America north of Mexico are eutherians.
The Wood between the Worlds is a pond-filled forest in The Magician’s Nephew (1955), the sixth book in The Chronicles of Narnia by C. S. Lewis. Each pond is a portal that provides instant transportation to a different world, such as Earth, Narnia or Charn. […]
The salient feature of the wood, other than the trees, is the presence of many pools of water. Initially, the pools appear to be just shallow puddles. However, when someone jumps into one of the pools while wearing another magic ring, the pool of water transports the wearer to a different world. When a world is destroyed by having all life removed (like what happened to Charn in The Magician’s Nephew), the pool dries up.
“This legend or myth or dim memory of some ancient history has always troubled me. In sleep I had the dreadful dream of the ineluctable Wave, either coming out of the quiet sea, or coming in towering over the green inlands. It still occurs occasionally, though now exorcized by writing about it. It always ends by surrender, and I awake gasping out of deep water. I used to draw it or write bad poems about it.” ― J.R.R. Tolkien, Letter 257

A networked narrative, also known as a network narrative or distributed narrative, is a narrative partitioned across a network of interconnected authors, access points, and/or discrete threads. It is not driven by the specificity of details; rather, details emerge through a co-construction of the ultimate story by the various participants or elements. […]
Networked narratives can be seen as being defined by their rejection of narrative unity.[1] As a consequence, such narratives escape the constraints of centralized authorship, distribution, and storytelling.

The Permian–Triassic extinction event, also known as the P–Tr extinction,[2] the P–T extinction,[3] the End-Permian Extinction,[4] and colloquially as the Great Dying,[5] formed the boundary between the Permian and Triassic geologic periods, as well as between the Paleozoic and Mesozoic eras, approximately 252 million years ago. It is the Earth’s most severe known extinction event, with up to 96% of all marine species[6][7] and 70% of terrestrial vertebrate species becoming extinct.[8] It was the largest known mass extinction of insects. Some 57% of all biological families and 83% of all genera became extinct.
According to Frank and Schmidt, since fossilization is relatively rare and little of Earth’s exposed surface is from before the quaternary time period, the chances of finding direct evidence of such a civilization, such as technological artifacts, is small. After a great time span, the researchers concluded, we would be more likely to find indirect evidence such as anomalies in the chemical composition or isotope ratios of sediments.[3] Objects that could indicate possible evidence of past civilizations inc

Meropis is situated beyond the world-ocean (Oceanus). Its inhabitants, the Méropes, are twice as tall as other human beings and live twice as long. Theopompos describes three cities in Meropis: Anostos (Ἄνοστος, “Place of No Return”), Eusebes (Εὐσεβής, “Pious-Town”) and Machimos (Μάχιμος, “Fighting-Town”). While the inhabitants of Eusebes are living in opulence getting neither hungry nor sick, the inhabitants of Machimos are in fact born with weapons and carry on wars steadily. The third city, Anostos, is situated on the outermost border of Meropis. It resembles a yawning abyss, does not have day or night, and is covered by cloudy, red fumes.
