National Geographic grantee Federico Fanti and his research team have unearthed a sea-dwelling crocodylomorph (a teleosaurid) skeleton in southern Tunisia, in the Sahara desert: Machimosaurus rex. It is the world’s largest marine crocodyliform and was previously unknown to science. Its length is estimated at more than 30 feet (9.14 meters). The giant was probably weighed three tons.
The fossil dates back 130 million years ago. The head of the crocodile alone is over 5 feet long. The discovery proves that this animal lived 25 million years past the hypothesized global extinction at the end of the Jurassic period.
According to a study titled “The Anthropocene is functionally and stratigraphically distinct from the Holocene” and published on Science Magazine, we, humans, changed the world so much that now we can say the world entered a completely a new geological era, “Anthropocene”.
The astronauts aboard the International Space Station (ISS) occasionally take photos of Earth. Some of them are really cool. Here are the top ten most beautiful Earth images taken from the International Space Station in 2015 (well, IMHO, of course).
Aboard the International Space Station, Expedition 46 Commander Scott Kelly of NASA, Flight Engineer Tim Kopra of NASA and Flight Engineer Tim Peake of the European Space Agency wished the people of Earth a Happy New Year. Kelly is nearing the completion of the ninth month of a year-long mission on the orbital laboratory, while Kopra and Peake arrived on December 15, 2015, to begin a six-month mission on the orbiting laboratory.
In 2010, during an expedition of the Spanish research ship Miguel Oliver, the researchers from the Smithsonian Tropical Research Institute discovered a new type of shark in the Pacific Ocean near Central America, off the coasts of Nicaragua, Panama and Costa Rica. The shark was glowing in the dark. Now it is officially a new kind of shark: its scientific name is Etmopterus benchleyi (it features a tribute to the famous 1974 novel “Jaws” author Peter Benchley), but since it is pure black, it is called “Ninja lanternshark”.
Almost 10% of the world’s land surface is currently covered with glaciers, mostly in places like Greenland and Antarctica. The amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth (332,500,000 cubic miles, or 1,386,000,000 cubic kilometers), but the majority of total freshwater on Earth, about 68.7%, is held in ice caps and glaciers. And if all land ice melted the seas would rise about 70 meters (about 230 feet).
What if all these ice melted? What would Earth look like? Alex Kuzoian of Business Insider prepared a video showing the effects of the global melting, and if it happens, “this would dramatically reshape the continents and drown many of the world’s major cities.”
Earth has a mild climate, which enables the life on its surface. But there are some places that exist which probably you won’t want to be there, at least uncovered. Here are the hottest and coldest places on our planet.
Photographers and wild animals – the wildlife photographers wait for endless hours to get the perfect shot, and sometimes they are surprised by the animals causing adorable pictures of their unexpected encounters.
Standing at 379.7 feet (115.7 meters) tall, a redwood tree named “Hyperion” is officially the tallest tree in the world.
Redwoods (scientific name: Sequoia sempervirens) are the tallest trees in the world, they easily reach heights of 300 feet (91 meters) and even more. They are not the tallest only, also evergreen and very long-lived: their lifespan is more than 1000 years, and some have been documented at even more than 2,000 years old.
They can grow up to 29.2 feet (8.9 meters) in diameter at breast height/dbh. Redwoods live in California, United States; and before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,100,000 acres (8,500 km2) along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States.
Now, unfortunately, an estimated 70% or more of ancient old-growth redwood trees have been displaced by environmental changes or cut down.
The World’s tallest tree
Among the redwoods, Hyperion dwarfs them all. The tree was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor, and is 379.7 feet (115.7 meters) tall.
The tree is estimated to contain 530 m3 (18,600 cu ft) of wood and to be roughly 700-800 years old. Researchers stated that woodpecker damage at the top may have prevented the tree from growing taller. According to Michael Taylor, “It’s possible it could’ve topped out at 380 feet (116 meters)”.
When I was a child, one of my favorite books was (and still is) Jules Verne’s Around the World in Eighty Days. Published in 1873, the novel tells the story of Phileas Fogg, an English gentleman, and his newly employed French valet Passepartout.
