Index – Technology – Fragments of a meteorite that destroyed dinosaurs were found

Scientists have discovered the immediate effects of the 66-year-old doomsday that led to the extinction of the dinosaurs at a North Dakota site. Research led by Robert DiPalma from the University of Manchester in 2019 New Yorker Described by Tanis as a “paleontological wonderland,” he worked on a former riverside site.

The site is located 3,200 kilometers from the site of the previous impact. The meteorite that struck the Yucatan Peninsula was probably about ten kilometers in diameter, but we don’t know much about it. We don’t know if it’s a comet, a solid mineral steroid, or rather a rocky mound bound together by its own gravity.

At the site of the impact, a crater 150 km wide and 30 km deep was formed, covering the environment with droplets of molten rock, which, when cooled, fell as a powder of small balls, suffocating both land and aquatic animals. This powder has been completely transformed by contact with water over millions of years and is now out of reach.

However, the thing is not hopeless if nature’s own time capsule, pine resin that turns into amber, helps. It hasn’t been reported by any scientific paper yet, but de Palma and colleagues found exactly this amber.

It was as if they could go back to the day of the crash to collect a sample, the paleontologist said in a report at NASA’s Goddard headquarters.

Some of the stones in misty amber contained significant amounts of strontium and calcium from the limestone at the site of impact. A fully incorporated rock containing more iron, chromium, and nickel was also found.

Based on this, the so-called carbonaceous chondrite can be the impacting asteroid. These meteorites, also called type C chondrites, contain large amounts of water and organic compounds. This also supports the geochemical theory of Frank Kite, who in 1998 found a similar fragment in a well eight thousand kilometers from the impact site in Hawaii that was thought to be related to the formation of the Chickxulub crater.

The DePalma team’s discovery will soon be shown on British public service television with the novel by David Attenborough. Not only amber was found at the special site, but a chaotic mass of primate corpses mixed with plant remains, which, like Pompeii, retained the imprint of the day of the destruction.

According to paleontologists, Tanis preserves traces of the massive tsunami that followed the impact of the meteorite. A dinosaur leg that was not present was found from a sick and dead animal or from a predator attack, but was torn apart by the force of the tsunami. If everything is correct, this will be the first remains that come directly from a dinosaur that was destroyed by a meteorite impact. No such discovery is known so far, nor is it essentially the remains of a dinosaur that lived close to impact for a few thousand years.
