Meet the Largest Dinosaur Ever Discovered

Argentinosaurus and Dreadnoughtus have got nothing on the Patagotitan mayorum. This newly named species of titanosaur is being called the world's largest dinosaur (and animal) to ever walk on land.

The long-necked herbivore, which weighed an estimated 69 tons—the equivalent of 12 African elephants—and measured 120 feet long, was discovered by an Argentinian rancher back in 2014. It made waves again last year when a model of its skeleton was added to the American Museum of Natural History, alongside its original fossilized femur.

Now, with a newly minted scientific name, the Patagotitan mayorum is on full display in National Geographic's recent video. You can take a gander at this stunningly complete specimen below:

The New Apple Watch SE Is Now Available on Amazon

Apple products are notorious for their high price tags. From AirPods to iPads to MacBooks, it can be difficult to find the perfect piece of tech on sale when you are ready to buy. Luckily, for those who have had their eye on a new Apple Watch, the Apple Watch SE is designed with all the features users want but at a lower starting price of $279— and they're available on Amazon right now.

The SE exists as a more affordable option when compared to Apple's new Series 6 line of watches. This less expensive version has many of the same functions of its pricier brethren, except for certain features like the blood oxygen sensor and electrical heart sensor. To make up for the truncated bells and whistles, the SE comes in at least $120 cheaper than the Series 6, which starts at $400 and goes up to $800. The SE comes with technical improvements on previous models as well, such as the fall detection, a faster processor, a larger screen, water resistance, and more.

Now available in 40mm ($279) and 44mm ($309), both SE models offer a variety of colors to choose from, such as sliver, space gray, and pink. If you want cellular connection, you’ll have to pay a bit more for the 40mm ($329) and the 44mm ($359).

100 Fascinating Facts About Earth

Did you know that there’s a place in the South Pacific Ocean called Point Nemo that’s farther from land than any other point on Earth? So far, in fact, that the closest humans are usually astronauts aboard the International Space Station. (And by the way: The map you’re about to look for Point Nemo on might not be entirely accurate; a certain amount of distortion occurs when trying to depict a 3D planet on a 2D surface.)

In this all-new episode of The List Show, Mental Floss editor-in-chief Erin McCarthy is journeying to the center of the Earth, and visiting its oceans, its atmosphere, and even space, in search of 100 facts about our endlessly fascinating planet.

The subjects that fall under the umbrella of “facts about Earth” are nearly as expansive as Earth itself. Geology, biology, astronomy, and cartography, are all fair game—and those are just a few of the many -ologies, -onomies, and -ographies you’ll learn about below.
