Researchers hypothesize that the asteroid that gave the world over to mammals and birds hit Earth at a 60 degree angle, kicking up far more atmospheric dirt than a direct hit. The resulting climate change would be deadly for massive fauna and the ecosystems that depended on them—as the fossil record shows.
Analysing the structure of the 200-kilometre-wide (125 mile) crater in southern Mexico where the asteroid hit, scientists ran a series of simulations. Lead author Gareth Collins of Imperial College London and colleagues at the University of Freiburg and the University of Texas at Austin looked at four possible impact angles - 90, 60, 45 and 30 degrees - and two impact speeds, 12 and 20 kilometres per second (7.5 and 12.4 miles per second). The best fit with the data from the crater was a 60 degree strike.
"Sixty degrees is a more lethal impact angle because it ejects a larger amount of material fast enough to engulf the planet," Collins told AFP.
Adds Collins: "a very bad day for the dinosaurs".
Every time I go back and watch an episode of Dinosaurs, I realize just how far ahead of its time it was (See: “What Sexual Harris Meant.” Also the series finale.) Also Tim Curry voiced a bunch of parts, which has nothing to do with the show’s cleverly subversive political nature, but is wonderful nonetheless. Here […]
Police in Murcia, Spain caught a Tyrannosaurus rex violating a coronavirus lockdown. The cops were kind enough to let the dinosaur off with a warning. From CBR: On the first released video, filmed by a neighbor, the T-Rex wannabe is clearly taking out the garbage. In the second video, however, it seems as if the […]
The tiny skull, about the size of a thumbnail, trapped in amber may belong to the smallest dinosaur scientists have ever discovered. Paleontologist Lida Xing of the China University of Geosciences spotted the skull in a 99-million-year-old chunk of amber from northern Myanmar. From the New York Times: [Xing, Chinese Academy of Sciences paleontologist Jingmai […]
Apple AirPods have become the default earbuds beloved by millions. Unfortunately, they also cost $159, so it’s no surprise that since they were first introduced in 2016, companies have battled to produce comparable headphones at a lower price. The UK-designed and engineered Veho STIX true wireless earphones may have cracked that particular problem, striking a […]
Instagram isn’t just for tweens and foodies. In fact, the image-heavy platform not only wants to mint new Instagram influencers — it also wants to make them rich. In the last few weeks, the company announced ad revenue sharing on IGTV videos, special badges you can buy from your favorite accounts through Instagram Live, merchandise […]
There’s a case to be made that animation might be the most labor-intensive storytelling method out there. For every second of finished film, animators have to create 12 different moving character images, each minutely adjusted to give the illusion of fluid motion. And that’s in addition to the background drawings and any other elements needed […]
